Introduction Sometimes you need a pocket torch and sometimes you need a head torch. And then, there are times your usage scenario is so versatile and complex that you need to cover all possible situations. We all have to make compromises with the EDC torch we carry and choose the one that is most likely to serve our needs for the day, but what if there was a torch that was so versatile it could eliminate the need to choose? Brinyte aspires to provide the answer to that question with their new Brinyte HL16 Noctua. The Brinyte HL16 Noctua is a headlamp like no other that I have seen, as its head rotates from 0 to 90 degrees, including 3 intermediate positions, thus providing unparalleled versatility and eliminating the need to compromise when choosing your EDC torch type. But what compromises did Brinyte have to make, if any, to realise such a unique and complex design? Read ahead to find out. Unboxing The Brinyte HL16 Noctua comes in a very nice cardboard box that is held closed with a blue paper ribbon, bearing the company's logo. The front of the box features a photo of the torch, emphasizing its articulated head and the magnetic charging capability. The back is less exciting, but provides a useful QR code to find out more about the product. The top and bottom of the box are plain white, while the longer sides feature the name of the torch and one of them has a photo of the torch mounted on the included head strap. Upon opening the box we find a card, explaining that the battery is already inside the torch, but insulated from the tail cap by an insulation film. The film has to be removed before the torch can be used. Inside the box we find a head strap, a magnetic charging USB cable, 2 spare O Rings and 2 leaflets. One of the leaflets is the warranty registration card which will allow the owner of the torch to extend its warranty from 2 to 5 years, free of charge, by registering the product on the company's website. The other leaflet is the user manual, which is easy to understand and includes helpful illustrations. The magnetic charging cable is 53cm long, including the plug and magnetic head. It is rather stiff and not at all like the much nicer charging cable that is included with the Brinyte PT18pro Oathkeeper, which is supple, sleeved, significantly longer at 102cm and features an illuminated magnetic charging tip. This is a definite downgrade from the magnetic charging cables of previous Brinyte models. Thankfully, the much nicer cable included with the Brinyte PT18pro Oathkeeper is compatible with the Brinyte HL16 Noctua. If the charging cable is a bit disappointing, the head strap makes up for it. It is very well made, has a good quality rubber cradle for the torch and adjustable size. The weaving is elastic and features ventilation holes which are a big help in warm weather. Finally, the torch itself! The Brinyte HL16 Noctua features a unique design, with an articulated head that can turn from 0 to 90 degrees. It is made of black anodized aluminium, with blue accents and has a large rubber button with the company logo engraved on one side and a magnetic charging connection point on the other. The head and the tail of the light feature a faceted milling design that provides both added grip and aesthetics. The articulated head is designed and executed with precision and definitely adds to the value and - I am sure - to the manufacturing cost of the torch. There are several detents visible, which means the head will not only stop in the 0 and 90 degree position but also in some positions in between. The clip is sturdy, thick and well designed. It comes positioned in the bezel up carry orientation and is as deep carry as can be, allowing for the articulated head. It can easily be removed and installed in the bezel down carry orientation, which makes the torch a very deep carry. With the clip removed, the Brinyte HL16 Noctua can be mounted onto the head strap. The front of the light features a crenelated bezel with an eye catching design. Inside the head sits a smooth reflector, which is unusual for a head torch as it will increase the throw, but taking into account that it is not very deep and that the torch is a multifunctional one, it was probably chosen to balance the beam for all uses. The tail cap is smooth and features a magnet that is not very strong but can hold the weight of the Brinyte HL16 Noctua in any orientation. Unscrewing the tail cap reveals the insulating film blocking the negative pole of the battery from making contact with the spring of the tail cap. Let's remove it. The included battery is a Brinyte branded 16340 Li-Ion battery, with a rated capacity of 650mAh. The spring in the tail cap is not thick, but should be sufficient for the current requirements of this torch. The head features a brass button battery contact, with no spring. Despite only having a spring on one side of the battery, hits and bumps did not cause the Brinyte HL16 Noctua to turn off. With the insulator film removed and the battery re-installed, the Brinyte HL16 Noctua is ready for action. Quality The build quality of the Brinyte HL16 Noctua does not allow for any complaints. The fit and finish are excellent, the milling is perfect and the anodization is without any flaws. Articulated Head The one unique feature of the Brinyte HL16 Noctua is its articulated head, that will turn from 0 to 90 degrees. The movement of the articulated head is smooth and enjoyable and makes for an addicting fidget toy. Besides the two extreme positions, the head of the torch will stop in 3, equally spaced, intermediate positions, thus allowing for the light to be directed where it is needed. This is a very nice and useful feature that I have not seen on any other torch available today. Size Comparison The following photos offer a direct size comparison of the Brinyte HL16 Noctua to the Olight S1R Baton II. The Brinyte HL16 Noctua is significantly longer, despite using the same size battery. This is a compromise Brinyte had to make to achieve the articulated head design. Nevertheless, the torch is still easily pocketable and the added functionality of the articulated head is worth the extra length. Tint and Beam Profile The tint of the Brinyte HL16 Noctua is above the BBL (greenish). It is similar to the tint of the Olight S1R Baton II but warmer, although that could easily just be due to the tint lottery. The emitter used in the Brinyte HL16 Noctua is not high CRI. We can also see from the angle of the beams that the Olight S1R Baton II has a floodier beam pattern than the Brinyte HL16 Noctua. The beam pattern of the Brinyte HL16 Noctua is well balanced although the smooth reflector makes it throw more than the average EDC or head torch. On the other hand, that helps balance the lower power, giving it about the same intensity and throw as the Olight S1R Baton II, despite having about half the Lumen output. There is a clear hot spot surrounded by the spill which gradually fades out. No ugly artefacts, despite the smooth reflector. Beam Shots I tested the Brinyte HL16 Noctua over a distance of 70m. The following video shows a comparison of the Brinyte HL16 Noctua to the Olight S1R Baton II. Driver The driver of the Brinyte HL16 Noctua is a linear, unregulated driver that uses PWM to dim the light, on all levels, except, of course, on full (High). 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 driver features thermal regulation, low voltage protection, over charge protection and reverse polarity protection. Specifications The specifications of the Brinyte HL16 Noctua , as found on the company's website, are as follows: Despite the table stating that the maximum output is 500 Lumen, the actual advertised output as stated in the manual is 520 Lumen. I have made Brinyte aware of the mistake in the table and they will correct it. The output is lower than other contemporary torches of this size and that is the 2nd compromise that Brinyte had to make so that the Brinyte HL16 Noctua can have its articulated head. This is because the thermal mass of the head is too small and the thermal conductivity through the articulation is too restricted to allow for higher output. Nevertheless, 520 Lumen is more than enough for any task expected from a torch of this size and the articulated head will definitely come in more useful than a few seconds of extra brightness. The Brinyte HL16 Noctua is IP66 rated which means it is dust tight and can withstand powerful water jets, but it cannot be submerged. That is the 3rd and final compromise, after the limited maximum output and longer body, that Brinyte had to make to allow for the articulated head. IP66 is more than adequate for normal use and unless you drop your torch into a puddle, you should be alright using it in any situation. The drop resistance rating is a respectable 1.5m, so the articulated head does not seem to limit the durability. The maximum throw is 140m, which is a lot for the 520 Lumen rating and is due to the smooth reflector. User Interface The user interface of the Brinyte HL16 Noctua is very simple and can be seen in the following animation. To turn the torch on, press and hold the button until it lights up. The torch features mode memory, so it will turn on at the last used mode. Press the button to cycle between the 4 main modes: High, Medium, Low, Moon. Press and hold the button to turn the torch off. Double click the button at any time to enter Strobe mode. Press again to go to the previously used mode. I disagree with the company's decision to make the UI go from high to low as I find this counter intuitive, especially on an EDC or head torch. When I am on Moonlight and need a little more light I would like to be able to go to Low without having to be blinded by High first. I also miss the ability to turn the torch on at Moon mode, regardless of the previously used mode. Some torches use press and hold from off to go straight to Moon mode, but as the Brinyte HL16 Noctua uses press and hold to turn on, this is not possible. I understand that the press and hold to turn on choice makes a lock function unnecessary, but I would prefer a Moon shortcut and a lock function. Modes and Run Times The brightness of the modes and the respective run times, according to the manual, are shown in the table below. I have added a row with my own measurements. It is very refreshing to see a company that does not overestimate their product's Lumen output! Kudos to Brinyte! Current Draw As the UI of the Brinyte HL16 Noctua goes from High to Low, so will our current draw measurements. The torch draws just over 1.4A on High, just over 0.5A on medium, 134mA on Low and 13mA on Moonlight level. The current requirements are not demanding and the battery is a standard 16340, so the Brinyte HL16 Noctua has the advantage to be able to run on any 3.7V Li-Ion 16340 battery. Charging The battery included with the Brinyte HL16 Noctua is rated at 650mAh and I measured it at 697mAh. The battery's internal resistance was measured at around 112mΩ. It is clear that the battery included with the Brinyte HL16 Noctua is of high quality. Another positive point for Brinyte. The torch has under voltage protection and turns off when the battery voltage drops to 2.77V. The indicative LEDs around the magnetic charging port are lit green during operation if the battery charge is from 100% to 40%, lit red if it is from 40% to 5% and blink red if it is below 5%. Charging the Brinyte HL16 Noctua is very easy. Just use the included magnetic cable that automatically attaches to the torch when you get it near enough. The other end of the cable is a standard USB A plug and can be connected to any USB charger or computer USB port. The indicative LEDs around the charging port will turn red while the torch is charging and turn green to indicate a full charge. Charging the Brinyte HL16 Noctua from 2.77V to 4.18V, where the charging terminated, took 2 hours, 18 minutes and 51 seconds. The maximum current drawn was 0.5542A, so any USB charger or computer USB port will be sufficient. A charger is not provided with the light but you can use your phone charger. Unfortunately, the indicative LEDs turned green way before the charging was actually completed, indicated by the green arrow in the chart above. The voltage of the battery at that point was around 3.9V and there was still a long time to go and a lot of energy the battery could absorb and store before the charging actually completed. This is a practice that some other companies, such as Olight, have as well and with which I do not agree. Brinyte maintains that this increases the battery life as it is not fully charged every time and also that most users will not take the torch off the charger the moment the indicative LEDs turn green. In my opinion, this is nonsense. I want to know when my battery is actually fully charged and not have to guess (or use measuring equipment as above) and if I want to give my battery a full charge to get the full run time it is for me, the user, to decide. Having indicative LEDs that lie to me and having to leave the torch on the charger for a longer time, with no visual indication of when the charging is actually completed is most inconvenient and has no advantage whatsoever. Output & Runtimes The Brinyte HL16 Noctua is rated at a maximum output of 520 Lumen and a maximum throw of 140m. 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 556 Lumen, which is 7% more than the advertised 520. ANSI output (at 30 seconds) was 510 Lumen and at 2 minutes it was still 463 Lumen. Then the output declined rapidly over the next 38 seconds to 315 Lumen. It then followed the gradual declining curve of the battery output and gave useful light for over an hour, as the specifications promise. The rest can be seen in the graphs below. The first graph is the full runtime graph. And here are the first 10 minutes, in greater detail. At the end of the battery life, the very low output fluctuates as the indicative LED flashes red to show that the remaining battery capacity is below 5%. The temperature was very well controlled, as you can see in the runtime graphs. The head and switch temperatures are close but there is some difference despite their close proximity, which demonstrates the thermal impedance of the articulated head. The maximum intensity of the light was measured at 5002.4cd, which translates to a throw of 141m. That is 1m more than the 140m advertised. Conclusion The Brinyte HL16 Noctua is a unique EDC sized head torch with excellent build quality and an articulated head which allows it to turn its beam from 0 to 90 degrees relative to the body of the light, including 3 intermediate stops. Its aluminium body is well made and hard anodized and the fit and finish are flawless. The torch meets and exceeds all of its specifications, which is refreshing to see as very few manufacturers respect their customers enough to provide true and accurate measurements. The head band provided is very comfortable, it is adjustable and the weave allows for ventilation. The clip is unidirectional and very well designed and can be installed in 2 positions, for bezel up or bezel down deep carry. The driver uses PWM to dim the output, so PWM is present at all output levels, except on High. 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 unique articulated design of the head of the Brinyte HL16 Noctua imposed some limits on this torch. The maximum output is lower than most comparable sized torches due to the thermal barrier imposed by the articulated head while its total length is increased and its waterproof rating decreased for the same reason. Nevertheless, the advantage provided by the design will outweigh the limitations for many users. Besides, maximum output is only available for about a minute on all small torches and after that, the output of the Brinyte HL16 Noctua is similar to theirs. The Brinyte HL16 Noctua is currently under mass production and scheduled to be available for purchase at the end of October 2021 from the company's website and the cost will be $69.98. Brinyte have provided a $10 discount code for the readers of this review, which brings the price down to $59.98. The discount code is: HL16Noctua Disclaimer: I get absolutely no percentage of the sales or any other personal benefits from Brinyte, except for the fact that the torch was provided for review free of charge. Let's list the Pros and Cons of the Brinyte HL16 Noctua: Pros + Unique articulated head design that allows for 0 to 90 degrees position, including 3 intermediate stops + Measurements show specs to be accurate and not exaggerated, showing respect to the customer + Good and balanced beam pattern + Good quality head strap + Magnetic charging + Magnetic tail cap + Included good quality battery + Low Voltage Protection, Over Charge Protection and Reverse Polarity Protection + Thermal regulation + Low power and charging LED indicator + Good quality unidirectional clip that can be placed in 2 positions, for bezel up or bezel down deep carry + Compatible with all 3.7V Li-Ion 16340 and with 3.0V CR123 batteries Cons - High to Low User Interface - Charging indicator indicates charging complete a long time before it is actually completed - Maximum output limited to 520 Lumen - Longer than most 16340 torches - IP rating limited to IP66 - The driver is not regulated and uses PWM to dim the emitter - The charging cable is a downgrade from the one included in previous Brinyte models TheLAB.GR Thanks to Brinyte for providing the torch for review Polymeros Achaniotis 16/10/2021
Introduction I am not really into tactical torches, as I prefer the EDC type, with many modes and complex user interfaces that the tactical ones usually lack. And to be honest, I was always wondering why can't tactical torches incorporate both the quick, simple, tactical operation and the versatility of more than 1 mode. Apparently, Brinyte thought the same when designing the Brinyte PT18pro Oathkeeper, which is a tactical torch with simple and quick tactical operation, without sacrificing multiple modes. In fact, it looks like Brinyte made no compromises when designing this torch and included everything, so the question becomes, how well did they implement all the features and does the torch live up to its ambitious specs? Time to find out. Unboxing I received my review sample of the Brinyte PT18pro Oathkeeper in a plain brown box, which is the practice of Brinyte with samples, to minimize the shipping costs. The retail version comes in a nice box. The light comes with a full accessory pack, which includes a holster, a charging cable, a couple of spare O-rings, a lanyard and the operation manual. The operation manual comes in a unique format, written on 4 cards, held together with a small clip. It includes all the information needed to understand and operate the torch. The holster is very well built. It has a Velcro closure, 2 side pockets that can carry extra batteries and a plastic belt loop with a 360 degree swivel. The Brinyte PT18pro Oathkeeper comes in two colours, black and desert tan. Our sample is the latter and I find it to be a beautiful and practical design. It is definitely too large to carry in a pocket, but that is what the provided holster if for. It features a large head, a side switch with LED indicator, a removable pocket clip (which is quite superfluous for a torch of this size), a tactical ring and what I will name a "claw ring", with an aggressive claw. On the opposite side of the side switch, there is a pad for the magnetic charging cable. The tail cap features 2 large, rubber buttons, for the tactical operation. The big head features a relatively deep and wide reflector, which is almost smooth, promising a beam with a lot of throw but also some useful spill, perfect for a tactical scenario. The rubber tail cap buttons are easy to use, even with thick gloves. The tail cap also includes a hole to attach a lanyard. The battery ships in the light itself, with an insulator tab preventing the negative pole of the battery from making contact. This has to be removed before the light can be operated. The battery is a Brinyte branded, button top 18650 Li-Ion battery, rated at 3100mAh. I think the size of the light warrants the use of the more energy dense 21700 battery type and I hope Brinyte will make that change in the next version. That would provide better run times and the possibility for higher output as well. After removing the tail cap, the claw ring can also be removed and, after that, the tactical ring, which features a lanyard hole. The clip just snaps on, and can be removed as well. There are 2 O-rings on the tail part of the light, one for the water proofing of the tail cap and the other to stabilize the tactical ring. The claw ring is very helpful at gripping the torch and getting it out of the holster both quickly and securely and also provides a very secure grip while operating the light. The aggressive claw is good looking and possibly useful in tactical situations but it will most certainly be illegal to carry in many countries, so Brinyte made it easily removable and the light can be used fully without it. The part of the claw ring that goes over the tail cap has 2 internal ridges that have to be aligned with corresponding grooves on the tail cap, for proper installation. The bezel of the light is also removable and the light can be used with or without it. It is not very aggressive and it is useful as it allows you to see if the light is on when it is head standing, so I see no reason to take it off. Maybe Brinyte is planning to release a more aggressive bezel, as an accessory or one made of stainless steel. The light features thick, good quality springs on both sides of the battery, which should ensure uninterrupted use if the torch is bumped or dropped and also reduce the electrical resistance, maximizing the output. The light fits in the holster comfortably and there are cut outs for the claw ring and for the part of the tail cap that is protruding from it. The cut out for the claw ring is much too large, which is strange for a purpose built holster. I wish they had made it a closer fit. The protruding tail cap, allows for tactical operation of the torch, even when it is in the holster and the cut out at the bottom of the holster allows the light to shine out of it. It seems like the lower part of the holster does not fit the head of the torch well, so the round hole is deformed quite a bit when the torch is in the holster. Even though the holster has very nice features and good quality, it should be refined, to fit the claw ring and the head of the torch more closely. Quality The quality of the Brinyte PT18pro Oathkeeper is that of a premium production torch. The fit and finish is perfect and the anodizing is flawless. My sample came with some paint chipping on the secondary tail switch housing and 2 small nicks on the back of the tail cap. As this is a review sample that may have been handled before, I cannot say if this is a common occurrence but I expect it is not. I am fairly certain that if a retail torch was delivered like this, Brinyte would replace the tail cap, under warranty. Specifications The main features of the Brinyte PT18pro Oathkeeper, as found on the Brinyte website can be seen below: Features Brinyte patented tactical ring design, easy to grab at top speed Compatible with one 18650 battery or two CR123A batteries Fast charging function Intelligent power indicator Regulated power supply maintains constant brightness Overcharge, over-discharge and overheat protection Reverse polarity protection prevents damage from improper battery installation Alloy aluminium reflector with professional optical analysis Aircraft-grade high strength aluminium AL-6061-T6 with premium Type III military hard-anodized anti-abrasive finish There is not much one could ask that is not in there. The technical parameters of the light, as found on the company's website, are as follows: Technical Parameters ANSI/NEMA FL1 Turbo High Middle Low Strobe SOS Output 2000+ Lumens 450+ Lumens 60+ Lumens 10+ Lumens 2000+ Lumens 60+ Lumens Runtime 1min + 90mins 150mins 930mins 1870mins / / Beam Distance 360+ m / 393.70+ yds Intensity 32000+ cd Impact Resistant 1m / 1.09yds Protection Proof IP68 Working Voltage 3.0 – 6.0V Dimension 164mm (Length) x 25.4mm (Body Dia) x 41mm (Head Dia) Net Weight 170g / 0.37lb (excluding battery) These are some ambitious numbers, for the size and type of this torch. We will certainly put them to the test. User Interface The user interface of the Brinyte PT18pro Oathkeeper combines the directness and simplicity that defines tactical operation with the option to have a more complex interface, controlled by the side switch, with more modes and usability. There is a very clear diagram in the manual that explains the operation of the light, in detail: Beam-shots The Brinyte PT18pro Oathkeeper produces a beam with a well defined hot spot that promises good throw. The hot spot fades into a greenish corona that whitens out towards the edge of the spill. There are numerous rings in the beam, which is normal for a smooth reflector. I tested the Brinyte PT18pro Oathkeeper over a distance of 70m, which is what I would expect a tactical scenario usage would be. The following video shows a comparison of the Brinyte PT18pro Oathkeeper with 2 very well known contenders, the 1800lm Olight M2R Pro Warrior and the 2200lm Olight Warrior Pro. I think the Brinyte PT18pro Oathkeeper is holding its own very well against the two very strong contenders. I will let each of you decide which one you prefer. Driver The driver of the Brinyte PT18pro Oathkeeper provided a steady beam, without apparent PWM on all 4 output levels of the light. It also features constant brightness levels (as we will verify in the runtime test) as well as overcharge, over-discharge, overheat and reverse polarity protections. That seems like a complete set of features and a very well designed driver Tint In the following photos you can see the tint of the Brinyte PT18pro Oathkeeper in comparison to the Olight Warrior Pro and the Olight M2R Pro Warrior. The pictures were taken with a manually set 5500K white balance. As you can see, the Brinyte PT18pro Oathkeeper has a cool white tint, while both Olight torches feature warmer tints. Charging The Brinyte branded, button top, 18650 Li-Ion battery that comes with the Brinyte PT18pro Oathkeeper is rated at 3100Mah. I measured the actual capacity at 3003Mah, using the Opus BT-C3100 smart charger. The internal resistance of the battery was measured at 92mΩ. The charge level of the battery is indicated on the side switch, as depicted below. The charging cable has a blue light on it that makes it easy to find in the dark and illuminates enough to help you locate the charging pad on the torch. As soon as you get the charging cable close enough to the charging pad, it snaps on magnetically. The indictor LED on the side button will turn orange momentarily... ...and then red, as the charging begins. When the charging is completed, the indicator LED will turn to green. If the indicator light remains orange, that indicates something is wrong. It could be dirt / debris on the charging surfaces or a malfunction. The under voltage protection will turn the torch off, as soon as the battery voltage drops below 2.8V. The charging from that level until full, took 2 hours, 5 minutes and 15 seconds. The diagram of the charging can be seen below. The charging terminated when the battery reached 4.19V. 1 minute after the light is turned off, the indicator LED on the side switch will turn on, to make it easy to find the light in the dark. The brightness level is perfect for the purpose of helping to locate the light in the dark without being distracting and is comparable to tritium vials. The power consumption of this function is negligible and it will take many months before it has any serious impact on the battery level. It can be turned on or off by holding the side switch down for 10 seconds. Current Draw So let us measure the power consumption of the Brinyte PT18pro Oathkeeper when it is off and also in all output modes. The clamp meter was calibrated first. The power consumption when the light is off is just 6mA. The torch consumes 119mA on low, which is rated to produce 10 lumens. Medium is rated at 60 lumens and consumes 206mA. High is rated at 450 lumens and consumes 937mA. Finally, turbo mode is rated at 2000 lumens and draws 6.5A. Here is a table with all the measured values and outputs. Output & Runtimes I measured the output and runtime of the Brinyte PT18pro Oathkeeper in my home made integrating tube. A high quality electronic thermometer with 2 probes was also use to monitor the temperature. One of the probes was placed near the side switch and the other on the battery tube. The Brinyte PT18pro Oathkeeper outperformed its own specs in both brightness and duration. The temperature regulation worked flawlessly and kept the temperatures very low, not exceeding 35.2 Celsius. I think the temperature setting is quite conservative and it could definitely allow for higher temperatures, which would in turn allow for longer turbo runtimes. The only measurement where the Brinyte PT18pro Oathkeeper fell slightly short of its specs was the light intensity. The Specs say it has an intensity of 32000cd while I measured 31567cd. This means that the throw is 360m in the specs while I measured it to be 355m. This is very close and can be attributed to differences in environmental conditions, which influence the measurements. Conclusion The Brinyte PT18pro Oathkeeper is a tactical torch, with dual tactical tail switches, offering Turbo and Strobe modes at the touch of a button. It also features a side switch, with a battery level and charge indicator LED, that allows for 4 output levels, Strobe and SOS functions. That is an excellent combination of tactical and EDC functionality, with no compromises in either. It features a deep (for the torch size) and almost smooth reflector which provides a well balanced beam with excellent throw and useful spill. The tint is a cool white. The quality of the machining is very good as is the anodization and the light is IP68 water proof rated. The feel of the switches is very tactile and the tail switches are easy to locate and use, even with thick gloves. The light comes with a full set of accessories, including a holster, a lanyard, spare O-rings and a pocket clip. It has both a tactical ring and a claw ring, which is easily removable, as it is probably illegal to carry in some countries. The magnetic charging is very easy to use and the provided battery is a Brinyte branded button top 18650, rated at 3100mAh, which I measured to be 3003mAh. I believe that for this size light, Brinyte could have used a 21700 battery, which would provide even better run times and output. That said, the light already exceeds its specs and the output and run times are very good. The driver has a full set of every protection possible and provides a stable and PWM free output. There is not much that can be improved on the Brinyte PT18pro Oathkeeper. The only possible upgrades would be the use of a 21700 battery and a better fitting holster. Well done Brinyte. The cost of the Brinyte PT18pro Oathkeeper comes to $135, which is justified for the build quality and multitude of features. Let's list the Pros and Cons of the Brinyte PT18pro Oathkeeper: Pros + Combination of tactical operation dual tail switches and multiple-mode side switch + High quality fit and finish + Flawless anodization + Magnetic charging + Constant current driver with full set of protections and no visible PWM + Well balanced beam, good for tactical use + Removable claw ring and tactical ring + Power and charging LED indicator + IP68 + Battery, holster, lanyard and spare O-rings included + Compatible with all 18650 batteries + Two CR123A batteries can be used if needed Cons - A 21700 battery design would be better, for this size torch - The included holster should have a better fit around the head of the light and a smaller tactical ring cut out.

Introduction Despite living in an age of rapid scientific and technological advancement, there is actually very little innovation going on. Companies focus more on marketing than research and development and "new" products seem more like copies of each other than developed and designed with the needs of the consumer in mind. As a reviewer I enjoy seeing products with true innovation, products that were developed with some actual thought in the design process. Such is the Brinyte T28 Artemis that Brinyte sent me to review. The Brinyte T28 Artemis is a hunting light and its design and function are specifically tailored for the job. With an interface that is intuitive and easy to use -with or without gloves- and a triple light source (white, red, and green) without the need to carry extra filters, the Brinyte T28 Artemis is the most complete hunting light anyone could wish for. Does that mean it is perfect? Well, nothing is and I do not expect this light to be the exception. But let's delve into the review and find out if Brinyte did justice to Artemis, the ancient Greek goddess of hunting. Unboxing I received the review sample in a plain cardboard box, but that is not what the consumer gets, as the Brinyte T28 Artemis normally comes in a nice retail package. Inside the box there is a comprehensive instruction manual, laid out on 3 cards, which are held together with a nice hook and lanyard. There are also some spare o-rings and a USB type-A to type-C charging cable, which is long enough to comfortably set the battery on a table while charging it and not have it hanging from the socket, as might be the case with the cables some other manufacturers provide. As this is a light that can be mounted on a riffle with the appropriate mount (not included), a remote switch is included in the box. The remote switch replaces the tail cap of the light, has a spiral cable and includes a button to power on or off and separate buttons for increasing or decreasing brightness. The back of the switch has an adhesive-backed Velcro patch, so the switch can be mounted and removed freely. The cable has a stress relief, to avoid damage from movement. The conducting spring is not particularly thick, but it should be sufficient, since the battery is only subjected to modest power draw. Last but not least, the star of the show, the light itself. A lanyard comes pre-attached to the tail of the light. The lanyard is of nice quality but I would prefer it to be adjustable and have a sturdier tying end. The aesthetics of the light are nice and seem to be permeated by a faint military air, in a modern way. The anodization is flawless and there are no sharp edges anywhere. The light can tail stand, but I would not trust it as the head is a lot wider than the tail. Headstands are a lot safer, and the crenellated bezel ensures you can see if the light is on. The battery ships safely inside the light casing, with one of its terminals insulated by a tab. The battery is a 21700 Brinyte branded and claims a capacity of 5000mAh. It has a USB C port near the positive terminal and can be directly charged with the provided cable and a charger. The Brinyte T28 Artemis features a spring on the driver end as well as the tail cap. This ensures the light will not turn off if bumped, as pressure is applied on both ends of the battery. The springs are similar to the one on the remote switch, nice quality but not thick. This is how the light looks with the remote switch installed. Quality There is not much to say about the quality of the Brinyte T28 Artemis. The fit and finish is as good as I have seen in any production light. The anodization is flawless and the controls are responsive and sturdy. The threads are nicely cut and even though thicker springs are always nice to have, if the light is not drawing much current they do not make an important difference. The lanyard could (and should) be adjustable and with a thicker tying end, but that is not a major complaint as it is replaceable. Specifications The features and technical parameters of the Brinyte T28 Artemis, as found on the manufacturer's website, are the following: FEATURING · Powered by one 21700 rechargeable Li-ion battery · Brinyte patented tri-color lighting sources switch design · Rotating head to zoom in and out the beam · Tail stepless dimmer switch design, easy to meet any brightness requirements · Threaded lens for more effective concentrating effect · Regulated power supply maintains constant brightness · Overcharge, over-discharge and overheat protection · Reverse polarity protection prevents damage from improper battery installation · Aircraft-grade high strength aluminum AL-6061-T6 with premium Type III military hard-anodized anti-abrasive finish TECHNICAL PARAMETERS ANSI/NEMA FL1 Turbo(White) Turbo(Red) Turbo(Green) Output(Flood/Spot) 650+/360+Lumens 140+/55+Lumens 130+/70+Lumens Max Runtime 135mins 220mins 270mins Beam Distance 525+m/572+yds 255+m/277+yds 340+m/370+yds Intensity 69600+cd 16480+cd 29160+cd Impact Resistant 1m/1.09yds Protection Proof IP66 Working Voltage 3.0-4.2V Dimension 182~196mm(Length) x 25.4mm(Body Dia) x 54mm(Head Dia) Net Weight 200g/7.05oz (excluding battery) Unfortunately, I do not have the equipment to measure the brightness of the light to compare to the claims. The weight is a bit more than claimed though, at 216.2g. The battery weight is 73.6g. The only point where I will have to strongly disagree with the specifications claimed is the "regulated power supply which maintains constant brightness". That is not the actual case as the driver is not a buck/boost driver and the brightness decreased as the voltage of the battery diminished. It would have been much better if the light actually featured a driver that maintained constant brightness until the voltage protection kicked in. User Interface The user interface is where the Brinyte T28 Artemis truly shines - pun intended. The light turns on with a 1.5 second depress of the tail switch. This ensures that accidental activation is unlikely. Nevertheless, it is not impossible, as it could happen in a backpack, so I would like to have seen a more secure lockout option. A momentary depress of the same switch will turn the light off. The brightness level is controlled by twisting the same switch, like a volume dial. It controls the brightness in a step-less way, from 2% to 100%. Step-less rotary control is my preferred user interface in any light, as it is the most intuitive way to accurately dial in the exact amount of light needed, something that can be important in hunting. A green LED next to the button confirms the light is working normally, which is a nice touch. Its brightness is low enough so it is not distracting. The button / dial is large enough to use with thick gloves, which is essential for hunting and verifies that a lot of thought went into design of the Brinyte T28 Artemis. The remote switch also has on / off and dimmer functions. On / off is controlled by a momentary depression of the central switch. + and - control the brightness. The sturdy, military styled selector at the front is the means to select the LED used. The Brinyte T28 Artemis has 3 LEDs inside, and this selector actually moves the one needed to the centre, behind the lens. That is a very clever design, as other hunting lights have to either rely on add-on coloured filters or separate reflectors / optics for each colour LED, limiting the optic size available to each LED and / or increasing the size of the light. The unique design of the Brinyte T28 Artemis that moves the required LED in place, allowing for the use of a single, large optic, is optimal. But not only is the Brinyte T28 Artemis a step-less rotary control light with 3 separate LEDs, it is also a zoomie. So, twisting the head will zoom in the light, focusing the beam and increasing the throw distance. The controls of the Brinyte T28 Artemis combine to create the most comprehensive, intuitive, easy to use and complete user interface I have seen to date. Beam-shots The Brinyte T28 Artemis uses a Fresnel lens. This will provide the nice, uniform beam of a conventional spherical lens, at a fraction of the size and weight. Behind the lens, are 3 LEDs, a white in the middle, flanked by a red and a green LED. The relevant selector with mechanically move the selected LED at the centre, behind the lens and connect it to the driver. In that way the Brinyte T28 Artemis can produce white, red or green light, using the full size of the lens. The beam in full flood is not very floody. As the light is meant for hunting, it will be used from middle to long distances, so it makes complete sense that it is calibrated for those distances. In full zoom, the beam is very concentrated. Here are the same, on a flat white surface. In full flood the Fresnel lens creates a very uniform beam, with a defining circle around it. The LED itself can be just spotted in the centre. In full zoom, some artefacts are visible, but that does not show in the real world, at long distances, where the full zoom would be used. Here is a short video, using the Brinyte T28 Artemis outside. Driver The driver of the Brinyte T28 Artemis uses PWM to control the brightness, even at full brightness. That is to be expected and the PWM was not visible to my eyes. The shortcoming of the driver that needs to be addressed is the fact that it is not regulated, meaning the brightness of the light is dependant on the battery voltage. As the battery charge is used up and the voltage drops, the light becomes dimmer. Tint The tint of the white LED in the Brinyte T28 Artemis seems to be an above the BBL, cool CCT. Here it is compared to some other lights. From left to right we have the Brinyte T28 Artemis, the Olight S2R Baton II, the Sunwayman V20C and the Fireflies E07 Ti/Cu. The beam-shots are with the Brinyte T28 Artemis in full flood, in mid zoom and in full zoom. And here is how the colours compare to the white lights. Charging and Runtimes To charge the Brinyte T28 Artemis, you have to take out the battery and plug it into your own charger, using the provided cable. A red indicator light in the centre of the positive terminal will signal the charging. It will turn blue when the charging is completed. The battery is a Brinyte branded 21700 lithium-ion with a claimed capacity of 5000mAh, which I actually measured to be 5040mAh, so right on the money. Voltage protection kicked in when the battery voltage dropped to 2.68V. Charging it from that level, took 3 hours, 56 minutes and 25 seconds. The charging terminated when the battery reached 4.19V. The maximum current drawn from the charger was 1.4248A, so your charger must be capable to provide at least that. If not, the battery will still be charged, but charging will take longer. The runtimes specified and measured are in the table below. The ones measured are by far greater than the specified values. It is apparent that the specified runtimes refer to where the light produced is bright enough to be usable in hunting. As the driver is not actually regulated, the brightness will drop with the voltage of the battery, so the light, after a point, will not be bright enough to be usable. I hope Brinyte will address the issue and make a new version with a buck / boost driver, as this is my only grievance with this light. The light may have gotten dimmer as the voltage of the battery dropped but there was no visible step down due to thermal regulation. That is to be expected from a 650lm light of this size. The highest temperature measured during the run-time tests was 45.6C. Current Draw The current drawn from the battery of the Brinyte T28 Artemis was measured in all configurations using a digital clamp meter. The calibration for both the tail and the remote switches was done first. Then the parasitic drain was measured, which is very low. Here are the measurements for the lowest and highest settings, using the white LED, for both switches. Here are the measurements for the lowest and highest settings, using the red LED, for both switches. Here are the measurements for the lowest and highest settings, using the green LED, for both switches. The table below contains all the measurements, in Amps. Conclusion The Brinyte T28 Artemis is a very well designed and executed hunting flashlight. It features white, red and green LEDs, a step-less rotary control and a zoom function with a Fresnel lens. Its IP rating of IP66 ensures protection from dust and powerful water jets, which is as much as anyone can expect from a zoomie and good enough for all hunting conditions. The light is solidly built, with good fit and finish and a flawless anodization. I wish the logo on the tube would align with something on the head of the light, but that is actually surprising expensive to ensure and definitely not worth the increase in price it would cause. The user interface is the most complete, comprehensive and easy it could be and designed to be used with thick gloves, if needed. My only grievance is that the driver is not actually regulated and brightness is directly dependant on battery voltage. It would be so much more useful and nice if the light could actually maintain constant brightness, regardless of the battery level. The cost of the Brinyte T28 Artemis comes to $145.50 which is justified for the build quality and multitude of features. It would be even more so, with a better, fully regulated driver. Let's list the Pros and Cons of the Brinyte T28 Artemis: Pros + Extremely intuitive and complete user interface + High quality fit and finish + Flawless anodization + 3 separate LEDs for white, red and green, moved into place at the centre behind the lens by a mechanical selector + Fresnel lens + Step-less rotary control + Zoom function + Remote switch for power and brightness control included + IP66 + 21700 USB C rechargeable battery with 5040mAh actual capacity Cons - Despite claims for a regulated driver that provides constant brightness, the brightness was actually dependent on battery voltage - Accidental activation is unlikely, but not impossible - The included lanyard should be adjustable and have a sturdier tying end TheLAB.GR Thanks to Brinyte for providing the light for review Polymeros Achaniotis 24/09/2020
