  1. Introduction A little over a month ago, I reviewed the Acebeam E70-AL 6500K and was impressed by its quality and performance. Being quite fond both of Titanium and of high CRI emitters, I could not resist testing the CRI95+ variant of the E70 in a Titanium host. Acebeam offers two finishes for their Acebeam E70-TI, a stonewashed finish and a PVD coated finish in rainbow colours. Titanium is a fantastic metal, being very strong and hard for its weight, but it is far from optimal for torches because of its poor thermal conductivity. That, coupled with the high CRI emitter, which by default has low efficiency and produces much more heat than the Cree XHP70.2, means that if you are after performance you would be much better off sticking to the Acebeam E70-AL 6500K. The Acebeam E70-TI CRI95+ is not about performance, it is about eye candy! The high CRI emitter offers a pleasant tint and excellent colour rendition that compliments the luxurious look and feeling of the Titanium host perfectly. So, Lumen hunters, that's your cue to exit. Tint snobs, high CRI lovers, Titanium devotees, follow me! Unboxing The Acebeam E70-TI CRI95+ comes in a white box with a clear window that allows a view of the light. The box emphasizes the 5 year warranty and the high efficiency, constant current boost circuit, both attesting to the high quality of the Acebeam E70-TI CRI95+. The back side of the box does not offer any more information on specifications, but rather the company address, a few QR coded links and the usual certification logos. My Acebeam E70-TI CRI95+ sample is neither the stonewashed nor the PVD coated version. It is a unique sample I procured from Acebeam at a reviewer's discount and it is Chromium Electroplated Titanium. And it is gorgeous! The top and bottom of the box have nothing printed on them, so nothing to show. One of the longer sides lists the possible applications of the torch while the other shows if the battery is included, the emitter type and a warning regarding safe usage. Regarding the emitter choice, there is 6500K, 5000K and the 95+ CRI 4500K LED that is featured in today's sample. The 6500K and 5000K are 6V Cree XHP 70.2 LEDs while the 95+ CRI 4500K is the GT-FC40 which is a 12V LED and comes with a different driver. The maximum output of the CRI95+ emitter is rated at 2500 Lumen, the 6500K at 4600 Lumen and the 5000K 10% less (according to a company representative). The box features magnetic closure and opens like a book to reveal its contents. The accessories include a charging cable, 2 spare O-rings, a storage bag and a lanyard, not pictured here as it came attached to the light. The leaflets include the manual, a warranty card, safety instructions and a note explaining the battery is in the light and the insulation sheet needs to be removed before use. The Acebeam E70-TI CRI95+ comes with the lanyard pre-attached. I removed the lanyard to better show the torch, which features a unique design that is very harmonious and pleasing to the eye. The bezel is crenulated and the head features alternating circular and oblong designs, which work well together. The 8 oblong grooves are meant to house 12x2mm tritium vials according to Acebeam, but are not deep enough to completely cover them, measuring only 1.60mm in depth. As the glass tritium vials are very fragile, protruding equals a 100% chance of breaking. I would suggest to Acebeam to either make the grooves deeper by 0.5mm or, if not possible, to not advertise them as fit to house 12x2mm tritium vials. The body of the torch features a helix design, with cut outs revealing the inner tube and creating a beautiful visual effect. It also features 6 oblong grooves where it connects to the head that are meant to house 6x1.5mm tritium vials and are perfectly sized for it. The tail part of the tube features tapped holes where the milled clip comes pre-attached. The clip features an oblong groove that fits a 12x2mm tritium vial perfectly and is deep enough for it. There are 3 sections at the back end of the body. One with the clip installed, one with tapped holes, where the clip could be moved to - no idea why though - and one with bigger holes, where the lanyard came pre-installed. Removing the lanyard is very easy but re-installing it requires thin tweezers, which is probably why the company opted to ship the light with the lanyard already installed. In total, the Acebeam E70-TI CRI95+ features an intricate design which looks quite busy but still harmonious and pleasing to the eye. The machining of such a design is not an easy feat, especially in Titanium and with the level of detail and quality we see here. The business end of the torch comes with a protective plastic film, which must be removed before use. Under the protective film, we can see the shallow orange peel reflector and the GT-FC40 CRI95+ 4500K emitter. The combination of such a large LED with the shallow OP reflector guarantee a very floody beam. The back end of the torch is quite simple. It is where the switch for the operation of the torch is located. I like the simple, recessed design of the switch which allows the torch to tail stand and helps to protect from accidental activation. Clicking the switch is both easy and satisfying, without too much resistance but with adequate feedback. The web address of the company is printed around the switch, which I find unnecessary and deducting from the aesthetics of the light. I do not mind the name of the light and the hot warning symbol printed at the front, but I would also prefer it if the CE and crossed out bin symbols were omitted. The head and body unscrew to reveal that the battery ships inside the light, with the positive terminal insulated for safety. The threads are thick and square cut and, on my sample, rather gritty. The battery is an Acebeam branded 21700 Li-Ion battery, rated at 5100mAh and it features a USB C port near the positive terminal. Both battery contacts feature thick, good quality springs. These are probably adequate, but I would have still liked to see double springs or spring bypass wires in such a powerful light, to reduce the resistance even further. This would not have changed the brightness, as the Acebeam E70-TI CRI95+ features a boost driver, but could have helped a little with efficiency and run times. As mentioned before, there is an inner tube, as the light features an electronic switch at the back and both the negative terminal of the battery and the switch need to be connected to the driver. On the driver end, the body contacts the outer tube and connects to the battery negative and the two gold plated contacts near the perimeter connect to the inner tube and transfer the switch presses. The spring in the middle of the driver makes direct contact with the positive terminal of the battery. Having springs on both ends makes the torch resilient to bumps and drops, as the battery is suspended between two springs under pressure and is not likely to momentarily disconnect and turn the light off. Quality The machining quality of the Acebeam E70-TI CRI95+ is very high. Even at close inspection, there are no flaws. No edge is sharp, not a single spot less than perfectly milled. This is indeed a top quality light. On very close inspection, the Chrome Electroplating is not as perfect as the milling, with some hairline marks present and the Chrome Electroplating not quite reaching inside the grooves, but as the production torches are either stonewashed or PVD coated, that will not be an issue there. Specifications The specifications of the Acebeam E70-TI CRI95+ are not clearly listed on the company's website but I was able to gather them and they can be seen in the following table: Of course, the Chrome Electroplating finish is just for my sample. The commercially available finishes are, as mentioned before, stonewashed and PVD coated. I weighed the Acebeam E70-TI CRI95+ at 138g without the battery and 218g with it. The GT-FC40 emitter has a CCT of 4500K and a CRI of 95+ while it also features high R9 (rendition of the colour red, which is rare even among high CRI emitters). Acebeam claims the Acebeam E70-TI CRI95+ can achieve a maximum brightness of 2500 Lumen. User Interface The user interface of the Acebeam E70-TI CRI95+ is simple and intuitive. Despite featuring a recessed button, and a lock mode, a double click is required to turn the light on. This prevents accidental activation of unlocked lights and protects even the most careless of users from accidental activations, which would be disastrous with such a powerful light. The user interface of the Acebeam E70-TI CRI95+ is as follows: From Off Double click to turn on (with memory for the 4 main modes), click again to turn off. Click and hold from off to turn on at Moonlight mode. Keep holding until if flashes three times to lock the light. Click and hold again to unlock into Moonlight mode. Triple click for Strobe. Click to turn off or double click for Turbo. From On Click to turn off. Hold to cycle through the main modes (Low, Mid1 ,Mid2, High). Double click for Turbo. Double click again to return to previous mode. Triple click for Strobe. Click to turn off or double click for Turbo. From Turbo, click to return to previous (before Strobe) mode. There is no way to go directly from Strobe to a previous, non Turbo mode. Acebeam does not provide the output ratings of each mode, but I measured them for you and you can see the actual numbers in the table below. Notice that the Turbo output slightly exceeds the specifications. Unfortunately, my equipment is unable to measure the brightness of the Strobe mode. Beam-shots The beam pattern of the Acebeam E70-TI CRI95+ is exactly what can be expected from a large emitter combined with a shallow, orange peel reflector. The light is very floody, with a large hot spot and a lot of spill. Compared to the Acebeam E70-AL 6500K with the domed Cree XHP70.2 emitter, the Acebeam E70-TI CRI95+ with the flat GT-FC40, has a bit more throw per Lumen and a tighter hot spot. I tested the Acebeam E70-TI CRI95+ outside, over a distance of 70m. The following video shows a comparison of the Acebeam E70-TI CRI95+ with the Acebeam E70-AL 6500K and the Fireflies E07 (with 7 Nichia 219b sw45k emitters). Driver The driver of the Acebeam E70-TI CRI95+ is a digitally regulated, constant current boost driver, which should be able to maintain constant brightness regardless of the battery voltage and also features smart temperature control, reverse polarity protection and low voltage protection. Very refreshing to see such a high quality driver. There is no PWM in any of the modes. Tint and Size Comparison The tint of the Acebeam E70-TI CRI95+ is a neutral - warm 4500K and seems to be slightly below BBL. This light is a joy to behold, provides excellent colour rendition (including red) and is very pleasing to the eye. In the comparison photo below, you can see the neutral - pink tint of the Acebeam E70-TI CRI95+ in the middle, compared to the green tint of the Acebeam E70-AL 6500K on the left and the rosier tint of the Fireflies E07 (with Nichia 219b sw45k emitters) on the right. The above photo also offers a size comparison between the lights. The Acebeam E70-TI CRI95+ is not a light that can be easily carried in your trousers pocket, but it fits fine in a winter jacket or a backpack. Battery and Charging The battery included with the Acebeam E70-TI CRI95+ is a 21700, rated at 5100mAh and features onboard USB C charging. The specifications of the Acebeam IMR21700NP-510A with Built-in USB C Port, as shown on the company's website, are listed in the following table: I measured the capacity of the battery at exactly 4716mAh which is rather low compared to its 5100mAh rated capacity. The battery's internal resistance was measured at 26mΩ. The light has Low Voltage Protection and turns off when the battery voltage drops to 2.8V. Charging the Acebeam IMR21700NP-510A with Built-in USB C Port is very easy. Just connect the provided cable or any other USB C cable to the charging port and its other end to a charger. Both USB A to USB C and USB C to USB C cables can be used as well as any charger, including the ones that support PD. This is very convenient as you can charge the Acebeam IMR21700NP-510A with Built-in USB C Port with any USB C cable and charger you have at hand. The LED on the battery lights up red to indicate that it is charging and turns green when the charging is completed, at 4.14V. The Acebeam IMR21700NP-510A with Built-in USB C Port took 6 hours, 22 minutes and 27 seconds to charge from 2.8V to 4.14V. The maximum current drawn was 0.899A, which is low for a 21700 battery and explains the very long charging time. A charging circuit which can support 2A charging would have been much better. As the specifications indicate that the standard charging current is 1A, I can't help but wonder if it would be OK to charge the battery at 2A through a charger with large enough cradles to fit a protected button top 21700. A very nice feature of the Acebeam IMR21700NP-510A with Built-in USB C Port is its ability to function as a power bank. This is facilitated by the USB A port on the included charging cable, but a USB C to USB C cable can also be used, even for devices that do not support power delivery. When the Acebeam IMR21700NP-510A with Built-in USB C Port is functioning as a power bank, its indicative LED turns blue. There is no information available regarding the current the battery can provide through its USB C port so I had to investigate. Anything above 2.7A and the circuit would immediately reset. I gradually reduced the current until I found it to be initially stable at 2A, which is a good output. Unfortunately, this only worked with a fully charged battery and after 40 minutes of drawing 2A, the circuit started resetting. At the end of the test, and after countless resets, the battery voltage was 3.14V. I tempered my expectations and tried drawing 1A from the battery and this seems to be the maximum supported current for the power bank function, as the battery was able to maintain it with stability for 3 hours, before the circuit reset a few times and then turned off. I would have much preferred it if it had turned off without the resets, as I am not sure if they could damage any sensitive equipment being charged. The battery voltage at the end of the test was 2.99V. The Acebeam IMR21700NP-510A with Built-in USB C Port is a battery packed with nice features such as onboard USB C charging and power bank functionality, along with a large 5100mAh capacity. Nevertheless, the actual capacity of 4716mAh and the slow charging speed leave something to be desired, especially considering the $23.90 price tag. EDC Bulb Acebeam offers an accessory which adds a lot of value to the Acebeam IMR21700NP-510A with Built-in USB C Port. It is the Acebeam EDC Bulb. The Acebeam EDC Bulb attaches to the top of the Acebeam IMR21700NP-510A with Built-in USB C Port and connects to the battery's USB C port to draw power. The installation and operation are explained in the animation below. The specifications of the Acebeam EDC Bulb as found on the company's website, are in the following table: This tiny plastic attachment adds a lot of functionality to the Acebeam E70-TI CRI95+ and is a must buy, especially since it normally costs only $3.99 and is currently on offer for a mere $0.10. Unfortunately, it is also out of stock. The modes that the Acebeam EDC Bulb supports, along with their respective run times, are listed in the table below: The Acebeam EDC Bulb is so simple and at the same time so useful and nicely implemented! It really adds value to the Acebeam IMR21700NP-510A with Built-in USB C Port. Current Draw The Acebeam E70-TI CRI95+ has a low parasitic drain that is below the ability of my clamp meter to measure. The Moonlight mode draws 129mA. The Low, Mid1, Mid2 and High modes need 302mA, 565mA, 1.295A and 2.167A respectively and Turbo requires 10.64A. If we compare those values to the ones we got from the Acebeam E70-AL 6500K we can clearly see how much efficiency is lost. This translates to less light and more heat. It is the price we pay for high quality light. Here is a comparative table showing the measured light output versus the current draw. This allows us to calculate the efficiency of each mode in both torches. As we can see the efficiency of the Acebeam E70-TI CRI95+ is much lower. Output & Runtimes The Acebeam E70-TI CRI95+ with the 4500K GT-FC40 CRI95+ emitter is rated at a maximum of 2500 Lumen. Acebeam does not declare its maximum throw. I do not own a multi thousand dollar worth integrating sphere, just a logging Lumen meter and a home made integrating tube. The array is calibrated with 3 separate, professionally measured lights and gives me consistent results, but there is definitely room for error and deviations are to be expected. According to my measurements, the maximum output (at turn on) was 2564 Lumen, which slightly exceeds the declared 2500 Lumen. ANSI output (at 30 seconds) was 2288 Lumen and the rapid output decline continued down to 896 Lumen at 1 minute and 12 seconds. It then declined gradually as the temperatures rose, to 840 Lumen over the next 1 hour, 29 minutes and 28 seconds. After that, it stepped down to Mid1 level for 2 minutes and 39 seconds and then dropped to Low level for a further 19 minutes and 2 seconds, before it turned off. While the output of the Acebeam E70-TI CRI95+ is good for its size and taking into account that it is using a very high CRI emitter, the low efficiency of that emitter along with the Titanium construction cause some extremely high temperatures to develop. The head of the torch exceeded 90°C! The body is somewhat protected because Titanium does not conduct heat well, but still reached over 60°C during the test. This is definitely not a light to hold in bare hands on Turbo for extended periods of time. The following graph shows the first 10 minutes of the Runtime Graph in greater detail. I also ran the test on High output. Thermals were more manageable this time as output was reduced. The body stayed below 55°C and the light output was stable and lasted for 2 hours, 10 minutes and 37 seconds on High, before it turned off. The following graph shows the first 10 minutes of the High Runtime Graph in greater detail. The light quality of the Acebeam E70-TI CRI95+ is really impressive and so is the premium feeling of the Titanium body, but efficiency suffers for it and thermals are a definite consideration. The torch is very usable, despite the low efficiency and high temperatures and I actually prefer it and use it much more than the Acebeam E70-AL 6500K because of the significantly better quality of the light it produces Acebeam does not specify the maximum intensity and throw of the Acebeam E70-TI CRI95+. I measured the maximum intensity to be 8932cd and the maximum throw at 183m. Acebeam E70-TI CRI95+ vs. Acebeam E70-AL 6500K The following graph compares the output and thermal performance of the Acebeam E70-TI CRI95+ to those of the Acebeam E70-AL 6500K. As expected, the Acebeam E70-TI CRI95+ has both lower output and less run time, while the temperatures are much higher. Notice the higher difference between head and body temperatures in the Titanium host versus the Aluminium host, which is indicative of the bad thermal conductivity of Titanium. The following graph shows the first 10 minutes of the comparison, in greater detail. For the first 10 minutes, the Titanium body is even more comfortable to hold than the Aluminium. It goes without saying that an Aluminium host and a high efficiency emitter win in performance. The high CRI emitter and Titanium host win in light quality and premium feeling. The choice is yours to make. Conclusion The Acebeam E70-TI CRI95+ is a light that emphasizes quality. The machining of the Titanium host is intricate with no imperfections or sharp edges. The driver is fully regulated and provides constant current output without any PWM on any of the modes. The GT-FW40 CRI95+ 4500K emitter is below the BBL and produces a very pleasant beam with fantastic colour rendition. The User Interface is simple and functional and extra care has been taken to prevent accidental activations. The size is normal for a 21700 light and not too easy to fit into trousers pockets, although not impossible. I would prefer to carry the Acebeam E70-TI CRI95+ in my backpack or in the pocket of a winter jacket. Or a holster, which should have been included. The optional Acebeam IMR21700NP-510A with Built-in USB C Port battery features USB C onboard charging and Power Bank functionality while the Acebeam EDC Bulb optional accessory adds a lot of usability and value. If you are looking for a premium quality torch that feels luxurious to hold and produces light equally as luxurious to look at, then the Acebeam E70-TI CRI95+ is a light you should consider. If you prefer efficiency and high output, then look at the Acebeam E70-AL 6500K instead. The Acebeam E70-TI CRI95+ can be purchased directly from the company's website and the cost at the moment this review is written is $208.80, including the battery and shipping, worldwide. The light without the battery costs $188.90, but keep in mind that only button top protected 21700 batteries that can provide at least 10.64A of current will work. Let's list the Pros and Cons of the Acebeam E70-TI CRI95+: Pros + Below BBL CRI95+ 4500K emitter produces excellent light quality. + Digitally regulated constant current boost driver which provides stable output and high efficiency with no PWM. + Luxurious Titanium Body construction. + Long runtimes. + Impeccable and intricate machining. + USB type C charging integrated in the battery. + Low Voltage Protection. + Quality springs on both sides of the battery. + Smart ITS Temperature Control. + Simple and intuitive UI. + 6 slots for 6x1.5mm tritium vials. + IP68. + The battery provides Power Bank functionality. + The Acebeam EDC Bulb optional accessory is very useful. Cons - Bad thermal performance. - Low efficiency. - The 8 slots on the head meant to house 12x2mm tritium vials are only 1.60mm deep and cannot protect the fragile glass vials so are not fit for purpose. - The battery is expensive. - The battery takes a long time to charge. - Actual battery capacity is 4716mAh instead of 5100mAh. - A holster should be included.  TheLAB.GR Thanks to Acebeam for providing a reviewer's discount for the light for review Polymeros Achaniotis 28/09/2021

    Acebeam E70-AL

    Introduction This review is brought to you by a stroke of good luck. I was looking at the Acebeam E70-AL as the design and specifications had caught my eye, when I stumbled upon a giveaway the company was doing on BLF. Tyche ruled in my favour and upon receiving my prize, I decided that a review was in order. Acebeam is well known amongst torch enthusiasts as a higher end company and both their products and their price tags reflect that. The Acebeam E70-AL may not be the most value for money option available but the specifications and quality are way beyond what you will find in budget friendly lights. Are you interested to see what the Acebeam E70-AL has to offer? Let's start at the beginning. Unboxing The Acebeam E70-AL comes in a white box with a clear window that allows a view of the light. The box emphasizes the 5 year warranty and the high efficiency, constant current boost circuit, both attesting to the high quality of the Acebeam E70-AL. The back side of the box does not offer any more information on specifications, but rather the company address, a few QR coded links and the usual certification logos. The top and bottom have no print, so nothing to show. One of the longer sides lists the possible applications of the light while the other shows if the battery is included, the LED colour temperature and a warning regarding safe usage. Regarding the LED choice, there is 6500K which is what my prize came with, 5000K and another option not depicted on the box, which has recently been added to the company's website, a 95+ CRI 4500K LED. The 6500K and 5000K are 6V LEDs while the 95+ CRI 4500K is a 12V LED and comes with a different driver. The output of the 6500K emitter is rated at 4600 Lumen, the 5000K 10% less (according to an company representative) and the 95+ CRI 4500K emitter at 2500 Lumen. The box features magnetic closure and opens like a book to reveal its contents and a thank you note from the company. The accessories include a charging cable, 2 spare O-rings, a storage bag and a lanyard not pictured here as it came attached to the light (as seen in the photos above). The leaflets include the manual, a warranty card, safety instructions and a note explaining the battery is in the light and the insulation sheet needs to be removed before use. I removed the lanyard to better show the light, which features a unique design. The Acebeam E70-AL is made of aluminium and has flawless machining and anodization. The anodization of the main body is black and there is an inner tube which is anodized blue. The design is very harmonious and pleasing to the eye. The bezel is crenulated and the head features alternating circular and oblong designs which work well together. The 8 oblong grooves are meant to house 12x2mm tritium vials according to Acebeam, but are not deep enough to completely cover them, measuring only 1.60mm in depth. As the glass tritium vials are very fragile, protruding equals 100% chance of breaking. There are some hard to obtain 11.5x1.4mm and 10x1.5mm tritium vials that would fit nicely but even if you can find them, the colour choice is quite limited. I would suggest to Acebeam to either make the grooves deeper by 0.5mm or, if not possible, to not advertise them as fit to house 12x2mm tritium vials. The body of the light features a helix design, with cut outs revealing the blue anodized inner tube and creating a beautiful visual effect. It also features 6 oblong grooves where it connects to the head that are meant to house 6x1.5mm tritium vials and are perfectly sized for it. The tail part of the tube features tapped holes where the simple and functional clip comes pre-attached. There are 3 sections at the back end of the body. One with the clip installed, one with tapped holes, where the clip could be moved to - no idea why though - and one with bigger holes, where the lanyard came pre-installed. Removing the lanyard is very easy but re-installing it requires thin tweezers, hence why the company probably opted to ship the light with the lanyard already installed. In total, the Acebeam E70-AL features an intricate design which looks quite busy but still harmonious and pleasing to the eye. The machining of such a design is not an easy feat, especially with the level of detail and quality we see here. The business end of the light comes with a protective plastic film, which must be removed before use. Under the protective film, we can see the shallow orange peel reflector and the Cree XHP70.2 emitter. The combination of such a large LED with the shallow OP reflector guarantee a very floody beam. The back end of the light is quite simple. It is where the switch for the operation of the light is located. I like the simple, recessed design of the switch which allows the light to tail stand and helps to protect from accidental activation. The web address of the company is printed in white, which I find unnecessary and deducting from the aesthetics of the light. I do not mind the name of the light and the hot warning symbol printed at the front, but I would also prefer it if the CE and crossed out bin symbols were omitted. The head and body unscrew to reveal that the battery ships inside the light, with the positive terminal insulated for safety. The threads are square cut, smooth and come nicely greased. The battery is an Acebeam branded 21700 Li-Ion battery, rated at 5100mAh and it features a USB C port near the positive terminal. Both battery contacts feature thick, good quality springs. These are probably adequate, but I would have still liked to see double springs or spring bypass wires in such a powerful light, to reduce the resistance even further. This would not have changed the brightness, as the Acebeam E70-AL features a boost driver, but could have helped a little with efficiency and run times. As mentioned before, there is an inner tube, as the light features an electronic switch at the back and both the negative terminal of the battery and the switch need to be connected to the driver. On the driver end, the silver ring seen on the perimeter contacts the outer tube and connects to the battery negative and the two gold plated contacts near the perimeter connect to the inner tube and transfer the switch presses. The spring in the middle of the driver makes direct contact with the positive terminal of the battery. Having springs on both ends makes the light resilient to bumps and drops, as the battery is suspended between two springs under pressure and is not likely to momentarily disconnect and turn the light off. Quality We have already seen the extraordinary quality the Acebeam E70-AL has, for a production light. Even at close inspection, both the machining and the anodization are perfect. No edge is sharp, not a single spot less than perfectly anodized. This is indeed a top quality light. Specifications The specifications of the Acebeam E70-AL, as mentioned on the company's website, can be seen in the following table: The Acebeam E70-AL is made of aerospace grade aluminium which has premium type 3 hard anodization. It features the very powerful Cree XHP70.2 LED which allows it to achieve an impressive maximum brightness of 4600 Lumen. The maximum throw distance is 240m, which means that the light is very floody, as expected from the configuration of the LED and the reflector. The Acebeam E70-AL is quite resilient and sturdy, with an IP68 water proof rating and a 1m impact resistance User Interface The user interface of the Acebeam E70-AL is simple and intuitive. Despite featuring a recessed button, a lock mode and the ability to hard lock the light by unscrewing the head 1/4 of a turn, a double click is required to turn the light on. This prevents accidental activation of unlocked lights and protects even the most careless of users from accidental activations, which would be disastrous with such a powerful light. The user interface of the Acebeam E70-AL is as follows: From Off Double click to turn on (with memory for the 4 main modes), click again to turn off. Click and hold from off to turn on at Moonlight mode. Keep holding until if flashes three times to lock the light. Click and hold again to unlock into Moonlight mode. Triple click for Strobe. Click to turn off or double click for Turbo. From On Click to turn off. Hold to cycle through the main modes (Low, Mid1 ,Mid2, High). Double click for Turbo. Double click again to return to previous mode. Triple click for Strobe. Click to turn off or double click for Turbo. From Turbo, click to return to previous (before Strobe) mode. There is no way to go directly from Strobe to a previous, non Turbo mode. The rated output and runtimes of all the modes can be seen in the table below. Beam-shots The beam pattern of the Acebeam E70-AL is exactly what can be expected from a large emitter combined with a shallow, orange peel reflector. The light is very floody, with a large hot spot and a lot of spill. I tested the Acebeam E70-AL outside, over a distance of 70m. The following video shows a comparison of the Acebeam E70-AL with the Emisar D4V2 Ti (with 4 Cree XP-L HI 5000K emitters) and the Fireflies E07 (with 7 Nichia 219b sw45k emitters). Driver The driver of the Acebeam E70-AL is a digitally regulated, constant current boost driver, which should be able to maintain constant brightness regardless of the battery voltage and also features smart temperature control, reverse polarity protection and low voltage protection. Very refreshing to see such a high quality driver. There is no PWM in any of the modes. Tint and Size Comparison The tint of the Acebeam E70-AL is cool white at 6500K (5000K and 4500K with high CRI options are also available) and it is definitely above BBL and distinctly green. This is by no means a pleasing tint nor is the light high CRI. The intend was to maximize output and efficiency. In the comparison photo below, you can see the Acebeam E70-AL in the middle, compared to the more neutral tint of the Emisar D4V2 Ti (with Cree XP-L HI 5000K emitters) on the left and the much rosier tint of the Fireflies E07 (with Nichia 219b sw45k emitters) on the right. The above photo also offers a size comparison between the lights. The Acebeam E70-AL is not a light that can be easily carried in your trousers pocket, but it fits fine in a winter jacket or a backpack. Battery and Charging The battery included with the Acebeam E70-AL is a 21700, rated at 5100mAh and features onboard USB C charging. The specifications of the Acebeam IMR21700NP-510A with Built-in USB C Port, as shown on the company's website, are listed in the following table: I measured the capacity of the battery at exactly 4716mAh which is rather low. The battery's internal resistance was measured at 26mΩ. The light has Low Voltage Protection and turns off when the battery voltage drops to 2.7V. Charging the Acebeam IMR21700NP-510A with Built-in USB C Port is very easy. Just connect the provided cable or any other USB C cable to the charging port and its other end to a charger. Both USB A to USB C and USB C to USB C cables can be used as well as any charger, including the ones that support PD. This is very convenient as you can charge the Acebeam IMR21700NP-510A with Built-in USB C Port with any USB C cable and charger you have at hand. The LED on the battery lights up red to indicate that it is charging and turns green when the charging is completed, at 4.14V. The Acebeam IMR21700NP-510A with Built-in USB C Port took 6 hours, 22 minutes and 27 seconds to charge from 2.7V to 4.14V. The maximum current drawn was 0.899A, which is low for a 21700 battery and explains the very long charging time. A charging circuit which can support 2A charging would have been much better. As the specifications indicate that the standard charging current is 1A, I can't help but wonder if it would be OK to charge the battery at 2A through a charger with large enough cradles to fit a protected button top 21700. A very nice feature of the Acebeam IMR21700NP-510A with Built-in USB C Port is its ability to function as a power bank. This is facilitated by the USB A port on the included charging cable, but a USB C to USB C cable can also be used, even for devices that do not support power delivery. When the Acebeam IMR21700NP-510A with Built-in USB C Port is functioning as a power bank, its indicative LED turns blue. There is no information available regarding the current the battery can provide through its USB C port so I had to investigate. Anything above 2.7A and the circuit would immediately reset. I gradually reduced the current until I found it to be initially stable at 2A, which is a good output. Unfortunately, this only worked with a fully charged battery and after 40 minutes of drawing 2A, the circuit started resetting. At the end of the test, and after countless resets, the battery voltage was 3.14V. I tempered my expectations and tried drawing 1A from the battery and this seems to be the maximum supported current for the power bank function, as the battery was able to maintain it with stability for 3 hours, before the circuit reset a few times and then turned off. I would have much preferred it if it had turned off without the resets, as I am not sure if they could damage any sensitive equipment being charged. The battery voltage at the end of the test was 2.99V. The Acebeam IMR21700NP-510A with Built-in USB C Port is a battery packed with nice features such as onboard USB C charging and power bank functionality, along with a large 5100mAh capacity. Nevertheless, the actual capacity of 4715mAh and the slow charging speed leave something to be desired, especially considering the $23.90 price tag. EDC Bulb Along with the light and battery, my giveaway prize included a nice little accessory which adds a lot of value to the Acebeam IMR21700NP-510A with Built-in USB C Port. It is the Acebeam EDC Bulb. The Acebeam EDC Bulb attaches to the top of the Acebeam IMR21700NP-510A with Built-in USB C Port and connects to the battery's USB C port to draw power. The installation and operation are explained in the animation below. The specifications of the Acebeam EDC Bulb as found on the company's website, are in the following table: This tiny plastic attachment adds a lot of functionality to the Acebeam E70-AL and is a must buy, especially since it normally costs only $3.99 and is currently on offer for a mere $0.10. Unfortunately, it is also out of stock. The modes that the Acebeam EDC Bulb supports, along with their respective run times, are listed in the table below: The Acebeam EDC Bulb is so simple and at the same time so useful and nicely implemented! It really adds value to the Acebeam IMR21700NP-510A with Built-in USB C Port. Current Draw The Acebeam E70-AL has a low parasitic drain that is below the ability of the clamp meter to measure. The Moonlight mode only draws 20mA. The Low, Mid1, Mid2 and High modes need 83mA, 216mA, 748mA and 1.961A respectively and Turbo required 10.40A. These values are rather low for the Lumen output and attest to the efficiency of the driver and emitter combination. Output & Runtimes The Acebeam E70-AL with the 6500K emitter is rated at maximum of 4600 Lumen and 240m of throw. I do not own a multi thousand dollar worth integrating sphere, just a logging Lumen meter and a home made integrating tube. The array is calibrated with 3 separate, professionally measured lights and gives me consistent results, but there is definitely room for error and deviations are to be expected. According to my measurements, the maximum output (at turn on) was 4494 Lumen, which is short of the advertised 4600 but still very close to the specs and definitely within the error margin of my equipment. ANSI output (at 30 seconds) was 3805 Lumen and the rapid output decline continued down to 1210 Lumen at 57 seconds. It then stayed stable at a very impressive for the size of the light 1218 Lumen for a further 1 hour and 54 minutes! After that, it stayed for 5 minutes at 153 Lumen and finally dropped to 53 lumen for a further 53 minutes, before it turned off. The temperature regulation was very good and the body of the light was within the ability of a person to hold with bare hands. The test was done indoors, without any cooling or ventilation, so the results will be even better outside. The following graph shows the first 10 minutes of the Full Runtime Graph in greater detail. The stability and efficiency of the Acebeam E70-AL are truly impressive and make for a very usable and reliable light. In contrast to the unregulated drivers used in more budget oriented lights, the driver of the Acebeam E70-AL features a constant current output, providing a stable and constant light output and long run times. Turbo output is short, as dictated by thermal regulation and the laws of physics, but it is there for the short bursts that it may be needed for. High output is incredibly steady and lasted for an impressive 1 hour and 55minutes, after the turbo activation, which is 10 minutes more than what the specifications say. According to the specifications, the maximum throw of the Acebeam E70-AL is 240m and the maximum intensity 14400cd. I measured 210m and 11005.28cd. I charged the battery of the Acebeam E70-AL with an external charger to 4.20V, to see if I can squeeze any more performance out of the light but the gain was minimal, increasing the maximum output from 4494 Lumen to 4561 Lumen, the maximum throw from 210m to 214m and the maximum intensity from 11005.28cd to 11437.92cd. Therefore, I think that the company's decision to terminate the charging at 4.14V and thus increase the longevity of the battery is correct. Conclusion The Acebeam E70-AL is a light that emphasizes quality. The machining is intricate with no imperfections or sharp edges. The type 3 hard anodization is uniform and without flaws. The driver is fully regulated and provides constant current output without any PWM on any of the modes, while being very efficient. The Cree XHP70.2 emitter contributes to the high output and efficiency of the light. The User Interface is simple and functional and extra care has been taken to prevent accidental activations. The size is normal for a 21700 light and not too easy to fit into trousers pockets, although not impossible. I would prefer to carry the Acebeam E70-AL in my backpack or in the pocket of a winter jacket. The optional Acebeam IMR21700NP-510A with Built-in USB C Port battery features USB C onboard charging and Power Bank functionality while the Acebeam EDC Bulb optional accessory adds a lot of usability and value. The Acebeam E70-AL can be purchased directly from the company's website and the cost at the moment this review is written is $94.80, including the battery and shipping, worldwide. The light without the battery costs $74.90, but keep in mind that only button top protected 21700 batteries that can provide at least 10.40A of current will work. Let's list the Pros and Cons of the Acebeam E70-AL: Pros + Digitally regulated constant current boost driver which provides stable output and high efficiency with no PWM. + High Turbo output for the size of the light. + Long runtimes. + Impeccable and intricate machining. + Perfect type 3 hard anodization. + Aerospace grade Aluminium Alloy construction. + USB type C charging integrated in the battery. + Low Voltage Protection. + Quality springs on both sides of the battery. + Smart ITS Temperature Control. + Simple and intuitive UI. + 6 slots for 6x1.5mm tritium vials. + IP68. + The battery provides Power Bank functionality. + The Acebeam EDC Bulb optional accessory is very useful. Cons - The 8 slots on the head meant to house 12x2mm tritium vials are only 1.60mm deep and cannot protect the fragile glass vials so are not fit for purpose. - The battery is expensive. - The battery takes a long time to charge. - Actual battery capacity is 4716mAh instead of 5100mAh. - A holster should be included.  TheLAB.GR Thanks to Acebeam for doing the giveaway and Tyche for providing the light for review Polymeros Achaniotis 24/08/2021

    Wurkkos TS30

    Introduction With the multitude of companies that make torches nowadays, it is getting very hard to distinguish between the true value for money offerings and the overpriced, low quality ones. Price alone, certainly cannot be the determining factor as there are a lot of cheap lights out there that are not worth even a small fraction of their seemingly bargain of a cost. Wurkkos is known as a good value for money brand and I thought it would be interesting to test one of their lights and see if they live up to their reputation. The model we will be reviewing is the Wurkkos TS30, which is one of their higher spec lights. So without further delay, let's see what the Wurkkos TS30 has to offer and how it will do under our microscope. Unboxing The Wurkkos TS30 comes in a a nice cardboard box with the company logo and colours. The box appears not to be specific to the Wurkkos TS30 as the model is only indicated on the sticker at the bottom. Opening the box, we are greeted with a very nice presentation. Everything is neatly arranged and protected within laser cut outs in the black protective foam. That is a really nice touch and stands out from some of the other budget offerings. Inside the box, besides the light itself, we can find the manual, a tab instructing the owner to remove the insulator from the battery negative before using the light and the accessories. The accessories consist of a lanyard, 2 spare O-rings, a battery spacer if anyone wants to use a 18650 battery in this 21700 light, a 1m USB A to USB C charging cable and a very aggressive strike bezel with 4 very long spikes. The Wurkkos TS30 is made of black anodized aluminium and is a medium sized light. It is definitely not an EDC, pocket friendly little torch, but it will easily fit in a backpack or large jacket pocket. It features a side switch surrounded by cooling fins, on the other side of which there is a rubber flap protecting the USB C charging port. The head is wider than the body, measuring at 49mm diameter, and features a stainless steel bezel with crenulations so you can see if the light is on when placed on its head. The body has a pattern which offers some grip, without being very aggressive. The flap is easier to open and close than some other lights I have used and seems quite secure. The Wurkkos TS30 features a smooth triple reflector for its 3 Luminous SST40 emitters. The tail cap has 2 lanyard holes and can allow the light to tail stand, somewhat precariously. The battery tube can be unscrewed from both the head and the tail cap. The threads are smooth and the diameter is different on each side so the tube cannot be reversed. The Wurkkos branded 21700 battery comes inside the light and there is the mentioned black insulating disk blocking the negative contact, for safe shipping. The head features a brass protrusion to make contact with the positive pole of the battery. The tail cap has a thick double spring, which looks more than capable of transferring a lot of current, with minimal losses. The 21700 battery that comes with the Wurkkos TS30 is wrapped in a white sleeve that features the company logo. Despite the fact that the Wurkkos TS30 is advertised with a 4800mAh 21700 battery, the one in my sample claims to be 5000mAh. We are going to test that. Strike Bezel One of the accessories that come with the Wurkkos TS30 merits special mention. It is none other than the very aggressive strike bezel. This is milled from a solid bar of stainless steel and cannot be too cheap to manufacture. Personally, I find it superfluous and it cannot be legally carried in the UK where I live and I guess in many other countries. But I get that some people may be into this kind of "tactical" stuff. In my opinion, the cost of manufacturing this bezel could go into improving something else, as the torch already comes with a very nice bezel. Exchanging the bezels is really simple. Just unscrew the one the light comes with and screw in the other. The light looks... quite unique with the strike bezel installed. Wurkkos advertises this bezel for self defence and breaking glass in an emergency. Quality The build quality, fit and finish of the Wurkkos TS30 is definitely beyond its price range. I was quite impressed by the fact that even the cooling fins are chamfered and the anodization is flawless everywhere, even on all the edges. The blowout of the Wurkkos TS30 in the image below shows that everything is laid out as it should be. All materials seem of high quality and fit for purpose. Specifications The specifications of the Wurkkos TS30, as found on the company's website, are as follows: As you can see, the Wurkkos TS30 uses 3 Luminous SST40 emitters to deliver its light output, which is rated at 5950 Lumen for the 6000K version, which we are testing and 5000 Lumen for the 5000K version. The maximum throw is rated at 480m. The light uses the included 21700 battery but can also be used with a high drain 18650 battery, with the included sleeve. It is IPX-8 rated for water resistance. The specifications state that the Wurkkos TS30 is 182 +/- 1g. I weighed my sample exactly at 178.7g. The battery weighs 74.1g, bringing the total to 252.8g. Not too bad for the power it packs. User Interface The user interface of the Wurkkos TS30 is quite simple and intuitive. The light features 2 modes, Stepped and Ramping. Out of the box, the light comes in Stepped Mode. Stepped Mode: From Off Click for on, click again for off. Click and hold from off to turn on at Eco (moonlight) mode. Keep holding until if flashes to change into Ramping Mode. Click again for off. Double click for Turbo. Click to turn off. Triple click for Strobe. Click to turn off. Quadruple click for lockout. Repeat to deactivate. From On Click to turn off. Hold to cycle through the main modes (Low, Mid, High). Double click for Turbo. Click to return to previous mode. Triple click for Strobe. Click to return to previous mode. Quadruple click for lockout. Repeat to deactivate. Ramping Mode: From Off Click for on, click again for off. Click and hold from off to turn on at Eco (moonlight) mode. Keep holding until if flashes to change into Ramping Mode. Click again for off. Double click for Turbo. Click to turn off. Triple click for Strobe. Click to turn off. Quadruple click for lockout. Repeat to deactivate. From On Click to turn off. Hold to ramp up or down. Ramping changes direction when the button is pressed again within 1,5 seconds. The light flashes to indicate reaching the lower or upper end of the ramp. Double click for Turbo. Click to return to previous setting. Triple click for Strobe. Click to return to previous setting. Quadruple click for lockout. Repeat to deactivate The brightness, runtime and beam distance of each mode can be seen in the following table. The Wurkkos TS30 features Mode Memory. This means that it memorizes the last brightness level used (except Strobe). Mode Memory cannot be deactivated. While the light is in lock out mode, you can access the Eco mode momentarily by holding down the button. If you prefer a mechanical lock, you can just unscrew the tail cap half a turn. This will disconnect the battery and is recommended for long storage. Beam-shots The beam pattern of the Wurkkos TS30 is exactly what can be expected from a triple light with smooth reflectors and 5x5mm emitters. Very close up the pattern shows a triangular shape but at any working distance it becomes perfectly round. There are several rings, typical with smooth reflectors and a well defined hot spot. Installing the strike bezel effects the shape of the beam a lot. I tested the Wurkkos TS30 outside, over a distance of 70m. The following video shows a comparison of the Wurkkos TS30 with the Sofirn SP36 Pro (also with Luminous SST40 emitters) and the Fireflies E07 (with Nichia 219b sw45k emitters). Driver The driver of the Wurkkos TS30 is not regulated and uses PWM to dim the light, on all levels, except, of course, on full. The PWM is visible to the camera but not visible to the naked eye, on any level. Even though I prefer constant current drivers, PWM is an efficient and cost effective way to achieve LED dimming and if it is done at a high enough frequency, as seems to be the case here, it is not a problem. The Wurkkos TS30 driver also features Advanced Temperature Regulation (set at 60 degrees Celsius), Low Voltage Protection and Reverse Polarity Protection. Tint and Size Comparison The tint of the Wurkkos TS30 is cool white at 6000K (5000K option is also available) and even though it is above BBL, it is not significantly green. This is actually quite a nice tint for a 6000K Luminous SST40 emitter. In the comparison photo below, you can see the Wurkkos TS30 in the middle, compared to the much greener tint of the Sofirn SP36 Pro (also with Luminous SST40) on the left and the much rosier tint of the Fireflies E07 (with Nichia 219b sw45k) on the right. The SST40 used in the Wurkkos TS30 are not high CRI. The above photo also offers a size comparison between the lights. Charging The battery included with the Wurkkos TS30 is a 21700, rated at 5000mAh and I measured it at exactly 4922mAh. The light has Low Voltage Protection and turns off when the battery voltage drops to 2.7V. The battery's internal resistance was measured at 42mΩ. These measurements show that a high quality battery is actually included with this light. The indicative LEDs on the switch of the Wurkkos TS30 show the level of the battery charge. Green means that the remaining charge is at least 30%, red that it is below 30% and flashing red that it is critical and the light will soon turn off. Charging the Wurkkos TS30 is very easy. Just lift the rubber cover and insert the provided (or any) USB type C cable to charge the light. Both USB A to USB C and USB C to USB C cables can be used as well as any charger, including the ones that support PD. This is very convenient as you can charge the Wurkkos TS30 with any USB C cable and charger you have at hand. The indicative LEDs on the switch flash red to indicate the light is charging. They turn green when the charging is completed, at 4.16V. The Wurkkos TS30 took 3 hours, 13 minutes and 28 seconds to charge the included battery from 2.7V to 4.16V. The maximum current drawn was 1.7466A, so a charger that can provide at least 2A is recommended. A charger is not provided with the light but you can use your phone charger. Current Draw The Wurkkos TS30 has a low parasitic drain that is below the ability of the clamp meter to measure. The Eco (Moonlight) Mode only draws 4mA. The Low, Mid and High modes need 352mA, 1.24A and 6.63A respectively and Turbo required 16.99A. Output & Runtimes The Wurkkos TS30 6000K is rated at 5950 Lumen and 480m of throw. I do not own a multi thousand dollar worth integrating sphere, just a logging Lumen meter and a home made integrating tube. The array is calibrated with 3 separate, professionally measured lights and gives me consistent results, but there is definitely room for error and deviations are to be expected. According to my measurements, the maximum output (at turn on) was 5000 Lumen, which is short of the advertised 5950 but still very respectable for the size and cost of the light. ANSI output (at 30 seconds) was 4563 Lumen and at 1 minute the output had dropped to 4401 Lumen. At 2 minutes the output had decreased to 2943 Lumen and then declined rapidly to reach 747 Lumen at 00:02:44, where it stabilized and slowly decreased to 454 Lumen from 00:02:44 to 01:45:10. Then a strange thing happened which I cannot fully explain. A slow oscillation in output started to occur, with its floor exactly where the declining curve of output would have been and its amplitude steadily rising. This means the output was at least equal and mostly higher than it would have been otherwise, even exceeding 1000 Lumen at some points. Then the gradual decline of the output resumed and the light turned off at 02:29:36, while it was still holding an output of 171 Lumen. All in all, a very useful output profile, managing heat, battery capacity and output quite well. The following graph shows the first 10 minutes of the Full Runtime Graph in greater detail. I did discuss the strange oscillation with a couple of electronics experts but without a look at the driver components (the driver is glued in place and not removable) they could not offer more insight into the cause. I think it is happening around the time the battery voltage is near the Vf of the emitters, but why that could cause this behaviour, I cannot say. If any electronics experts can offer an explanation, I would appreciate leaving it in the comments. Conclusion The Wurkkos TS30 is a value for money light that will not disappoint. Its aero grade aluminium body is well made and hard anodized and the fit and finish are beyond its price point. The attention to detail is also there, with chamfered cooling fins and impeccable anodization. The size and weight are great for its output rating and the provided 21700 battery allows for ample runtime. The output is more than enough for most purposes and the beam profile is well balanced. The tint of the Luminous SST40 LED is a cool, slightly above BBL but without being too green tint. The CRI is low, but this is countered by the high lumen output these emitters allow the light to achieve. The driver uses PWM to dim the output, so PWM is present at all output levels, except on full. The frequency of the PWM is high enough to not be visible to the naked eye and did not tire me when using the light. The Wurkkos TS30 can be purchased directly from the Wurkkos Website and the cost at the moment this review is written is $45.99, including shipping, worldwide. That is a lot of torch for the money! Let's list the Pros and Cons of the Wurkkos TS30: Pros + Value for money + High output and throw + Aerospace grade Aluminium Alloy construction + Impeccable anodization and fit and finish + USB type A to C and type C to C charging + Low Voltage Protection + Advanced Thermal Regulation + Well balanced beam + 21700 Li-Ion 5000mAh battery included + Low power and charging LED indicators + Simple and intuitive stepped and ramp UI + IP68 + At least 2.5 hours of usable light per charge + Compatible with all high drain 21700 batteries Cons - The driver uses PWM to dim the emitter. A regulated, constant current driver could have been used instead of including the strike bezel.  TheLAB.GR Thanks to Wurkkos for providing the light for review Polymeros Achaniotis 05/08/2021
