Packaging & Accessories

The TT20 is using Thrunites standard heavy but minimal cardboard box. It’s lacking information like normal but that’s fine since it’s designed for online direct to consumer sales. Inside you get the flashlight itself, along with the proprietary 5000mAh 21700 battery, a basic holster, and a USB-A to C cable. The extras bag includes 2 Orings, a spare rubber tail boot, extra orings, 2 spare USB Charging port covers, and a branded lanyard. 

Construction

The Thrunite TT20 is available in 2 colors currently, a standard black and a Red “Outsider” edition that I have here. It’s a really nice rich vibrant red, I always like seeing lights in different colors. This version replaces the TT20 model number engraving with the Outsider’s logo. (Youtuber).

Thrunite added a large mechanical tail switch on this light making it “tactical” It’s cover is grippy and you can connect the lanyard at either side of the tail switch. It has some straight knurling for trip to help remove the tail cap. Inside the center contact is slightly spring loaded.

Threads are anodized and square cut. The battery compartment has very tight tolerances with the battery, when inserting the battery it’s cushioned by a layer of air escaping, normally you don’t see these types of tolerances in production lights. It doesn’t suffer the problem of the USB port cover popping off either which you sometimes see when inserting batteries in lights. The surface of the light has a fairly tame grip level for a tactical light, it’s a similar milled pattern to what the TC15 and T2 have. The 2 way clip is reversible on either end of the light, I have switched mine from where it came preinstalled. 

The head of the light is pretty plain, and glued to the body of the light at the front. You have an anti roll ring at the front. The e-switchis similar in shape and design to other Thrunites but this time black anodized and seems to stick out slightly more.It’s still got the LED indicator underneath for battery power levels. The battery charging port is opposite, and it has a fairly large silicon cover. The little pull tab can get in the way causing the flap to open unintentionally. The front of the light has a scalloped bezel that’s non tactical but allows light to escape when standing on the head. The lens is anti reflective coated, and underneath is a deep smooth reflector and the LED is nicely centered. The light is IPX8 water rated and had no issues with time in a bucket of water.

 

Size & Weight

I measured the length at 136mm, max diameter at 29mm, minimum diameter at 26.5mm. Weight with the battery and clip installed is 181.1g. For me I find it fits in the hand pretty well and it’s a decent size for a 21700. Not the smallest light in it’s class but not the largest either. 

 

Comparison

The Olight M2R Pro is the most obvious light I have as a competitor. It also is a 21700 battery, tactical tail switch with front button, and a similar overall size. Weight wise it’s within 1 gram. I think the Olight is a bit more tactical, with the more aggressive bezel, more aggressive body section grip, it’s more focused beam, and the 2 stage tail switch. Clip wise I have to give the advantage to Olight but the TT20 is good too. See the pictures below for how it compares to the Thrunite T2 and TC15.

 

Retention

The TT20 comes with a lanyard that you can attach onto the tail cap if you wish. This is approaching the size of light where I start to use lanyards, but for now I will leave it off. It also comes with a holster, it does the job but is fairly basic, with just a D-ring and belt loop. This is one area where the Olight M2R Pro’s holster is clearly better.

 

The pocket clip on the TT20 is dual direction and pretty good. It allows for a fairly deep carry in the pocket with only about 10mm of the light sticking out of the pocket. The clip is mountable on the front of the body tube or the rear. I suspect most people will rear mount it like I have it here. It’s a non captured clip so it does rotate around the body of the light. The TT20 will fit on a hat if you want it to but with the 21700 battery it’s heavier then I normally want to do with a strap on clip.

LED & Beamshots

The TT20 is using the Luminus SST70 LED in cool white. This is my first light with this LED as it’s fairly new and new to the flashlight market as well. It’s an XM Size LED, Quad die LED so it would be a replacement for a Cree XHP50, but it’s physically smaller, more like and XHP35. With it installed here in the TT20 there is a small donut in the beam at distances less then 3”. At low powers, I get a bit of green/yellow in the beam, but these go away at moderate power levels and the beam is a cool but not cold tint. There is a moderate hot center and the spill is moderate. There is a small ring at the outer edges of the spill.

This gets a bit into the UI of the light but during ramping it’s not a smooth ramp. It seems as if there are a ton of small fixed steps as it’s increasing or decreasing in brightness instead of a nice and smooth ramp like you have on most lights with ramping. Once you stop it’s even and I don’t notice any PWM to my eyes or camera. My scope says there is a tiny bit, so no concerns. 

Working voltage is 2.7V-4.2V which means you are only using the “proprietary” 21700 that the light comes with. FIrefly is measured at 0.5 lumens, infinity low starts at 31 lumens up to 1468. Strobe is 1294 lumens and Turbo is 2526.

 

Heat & Runtime

I did my runtime tests with the included battery at room temps of around 73F, non cooled. Turbo on the light lasts for 1:15 before it starts stepping down and it’s stable again at the 3 minute mark at around 23% relative output. I saw peak temps at 1:30 of 52C. The light was able to hold this 23% relative output for a long time, 3:30:00, total runtime was 3:36:00. LVP was measured at 2.849V. The standout for me is if you just skip turbo and run the light in infinite high, it’s around 1300 lumens and the light is able to hold this for a little over an hour (75 min).

When I compare the runtimes to the Olight M2R Pro, the Olight is able to withstand it’s turbo output slightly longer at about 5 minutes (while stepping down), and it’s bulk of the runtime was closer to 38% but for a shorter 2:33:00 and a total runtime of 3:15:00. 

 

UI

The UI on the TT20 is different for a tactical light. It’s ramping with the use of the front button. It starts on low and if you long press from off the light comes on in firefly mode. Once on in normal mode you can press and hold and the light will begin it’s ramp up, as mentioned the ramp isn’t very smooth or fast. A full ramp from low to high takes 5.44 seconds which is a long time in my opinion. The light flashes at both ends 3 times and you can ramp in a loop low to high then ramping back down to low. It’s harder to start the light out in low especially if coming from moonlight mode. Double click on the front switch to jump to Turbo or use the tail switch to go to turbo at any time. Triple click the front button to get into strobe. There is memory as well for modes other than Turbo. When using turbo from the tail switch you can’t adjust the mode.

 

The light does have electronic lockout mode, if you are a subscriber here you know I rarely if ever use lockout through the UI. Thankfully mechanical lockout is an option by just breaking contact with the tail. This will prevent the tail from working but the E-Switch will still work thanks to that proprietary battery. The light basically has 2 physical paths for current to flow. I find myself sometimes turning on electronic lockout accidentally here if I press to long to get to firefly mode.

 

Charging

The TT20 has a onboard USB-C port for charging. It’s only compatible with USB-A to C, and not full C-C or USB-C PD unfortunately. Total charge time was 3:03 which is pretty good. Max charge speed I saw was 2.1A. The curve here is different from I typically see but it did decline as the battery charged. The battery measured as full at 4.199V.

The battery will charge in some external chargers too if you have a large or pointy contact to make it over the plastic spacer on the battery. Alternatively if you have a charger that accepts long cells like the VapCell S4 Plus I recently reviewed, then a 1mm rare earth magnet will work as a spacer if needed. With the S4 I don’t need a spacer it turns out.

As mentioned before the 5000mAh 21700 battery here is proprietary since it has both the positive and negative contact on the traditional positive end of the light, and it has small plastic spacer here. The battery is interchangeable with the Thrunite T2 and Olight 21700’s like what’s on the M2R Pro. The Olight battery will run in the Thrunite TT20, but not the other way around. This is done to reduce the lights diameter, so it can run without an inner tube, so the E switch and tail switch can both operate. 

 

Pro’s

  • Body Color options, but I wish these were not cobranded. 
  • Better value and longer overall runtime then the main competition.
  • It can sustain a high percentage of infinite high for quite a while.
  • New SST70 LED that I think we will be seeing a lot more from manufactures, hopefully in Neutral white soon. 

 

Con’s

  • The red anodizing is a great color but doesn’t seem to be as durable as black.
  • Ramping isn’t steady and suffers noticeable PWM during the ramp. It’s also slow.
  • The UI here isn’t my favorite, it’s a clumsy mix of what I will call Everyday tactical.

 

Conclusion

My conclusion I come away with this light is, is it really tactical? The inclusion of the ramping suggests to me it’s more for general everyday use, with the tail cap being the more tactical feature since it allows you to go to full turbo instantly, but when using the tail option you can’t adjust the mode and it’s only turbo. I like how with the Olight M2R Pro, the tail switch is 2 mode, so it’s easy to get to but you have the option of if you want full power or not. 

To me the TT20  more everyday tactical than full on tactical. The beam to me is more everyday than tactical too with it being less focused and more flood then the M2R Pro. That said the TT20 is a nice value compared to many othe the other 21700 lights in the price category. It’s nicely made and carries better than I expected in the pocket. The runtime on infinite high is great too, It’s easily able to sustain over 1000 lumens for over an hour. In my opinion I can recommend the TT20 for general use if you’re OK with the UI and slow ramps but I probably wouldn’t recommend it for a true tactical operator type situation.

Reylight Quad Dawn Maratac (21700, 4000 Lumens, Cree XPL-Hi, 5000k)

Today I have the new Reylight Quad Emitter Dawn flashlight by Maratac. It’s a CountyComm exclusive light producing 3200 lumens out of 4 Cree XPL-HI LED’s in 5000k and can be powered from a 21700 or 18650 battery. It’s got this really nice dimpled style texture on the body all done in this grey type 3 anodized body. Let’s take a deep dive on this light and show what it’s capable of.

Packaging and Accessories

The Reylight Maratac Quad Dawn packaging is very simple. It ships in an orange hard plastic case with foam inside, some extra orings, and a plastic spacer for running an 18650 if you want to. The case is nice to store the light in but great to put other stuff in too. CountyComm is shipping these with a Samsung 40T 21700 battery but no charger. No manual is included but it’s a pretty simple 4 mode interface so you don’t need one. 

 

Construction

The light is made from 6061 aluminum and type 3 hard anodized in a gray matt finish. Starting at the tail switch, it’s a recessed textured rubber boot with a mechanical switch underneath. It has a satisfying feel and sound too it. The clip attaches at the edge of the light, using 2 purple anodized titanium screws and a titanium clip. I will talk more about the clip in the retention section. The only branding is opposite the clip, and it has the Maratac logo and the serial of the light. This minimal branding is great! 

 

The body and tail are a one piece design. I really like the almost golf ball like dimpling on the body of the light. CC says this increases the gripping surface by upto 300% over standard knurling, I don’t know how they come up with this calculation but I just like the feel in my hand and different look to most other lights on the market, and it won’t tear up your pocket insides. The head grows in diameter and has 4 tear drop shapes milled into it the length of the head. It’s a design feature that is common on many other ReyLight designs, like the LAN, and Gemini. 

 

At the front the bezel is raw aluminum to provide some contrast and when standing on the head it allows light to leak out letting you know if it’s on or not. The lens is sapphire, which is great for scratch resistance. Below that is the quad carillo style optic and LED’s. There is a green glow gasket underneath, it’s reasonably bright but definitely not turbo glow. 

 

 

 

Size and Weight

I measured the light at an overall length of 121.78mm, a minimum diameter of 25.5mm on the body and a maximum diameter on the head at 28.2mm. Weight with my 21700 battery is 140.1g. With a 30Q and spacer the weight was 127.6g.

The light is narrow for a 21700 and quad emitter light. Here are a few comparisons to similar quads or 21700 lights. 

 

Retention

For retention this light has the same pattern Reylight has used on the Dawn and Gemini flashlights. It’s a wide paddle clip that has the popular Steel Flame spacing for the screw holes, so you can upgrade to a skull clip if you like. The stock clip is 1.2mm Thick and quite stiff. It’s a bit of a challenge to get it to clip to my pants pockets. That said it’s very secure and isn’t going to go anywhere once clipped. I like how this light feels in my hand, it’s the perfect size for me and that dimpled texture gives a nice grip.

LED & Beam Shots

The Reylight Quad Dawn by Maratac is using Cree XPL-Hi LED’s in 5000k tint so it fits that classic neutral white tint, but to me it seems on the cool side of 5000k. My preferences in recent years has opted to the warmer emitters but this is nice too. The optic is all flood, and it’s pretty even with no real distortions, not something you see on all quads. The beam has a broad center with a slight corona, and the overall shape is slightly square at short ranges. 

Quad Dawn Beam Shot 

Reylight Krystal Beam Shot 

 

The middle 2 modes exhibit some PWM, It’s not bad and my eye or camera can’t see it but my scope can. See the example below. 

 

 

Heat and Runtime

The Reylight Quad Dawn by Maratac has quoted outputs of 2 lumens, 250 lumens, 1400 lumens and 3200 lumens. I did my runtime test with an Xtar High Drain (42A) 4200mAh 21700 battery because that’s what I had two of. I did a complete runtime in Turbo, which isn’t recommended because of the extreme heat, but it’s how I test all my lights in the brightest possible mode and see where they go from there. On this light it starts stepping down pretty soon after and a 0:2:25 it’s down to 50% relative output. From here it holds itself for an hour  before stepping down again and ending at around the 1:15:00 mark. During this time the light gets super hot, a whopping 78.9C (174F). This is dangerously hot, for both the battery and your skin. Again this isn’t recommended, CountyComm recommends only using “turbo” for 90 seconds and when you do that the light steps down much less and remains a warm but reasonable temp of less then 60C. I tested High only mode and fell a little short of the 2 hour quoted runtime but my battery is also 800mAh short of what the light ships with so I expect it to hit that without issue. 

 

UI

The UI here is super simple, it’s a 4 mode flashlight, with moonlight, low, high and turbo. Mode spacing varies quite a bit, between 2, 250, 1400, and 3200 lumens. The mechanical button can accept half presses while on to advance the modes and then a full press to lock in on. There are no flashing modes on this light, which I am cool with. The light doesn’t have memory mode.

 

Pro’s

  • I love the golf ball style dimpled texture on the body, it’s different and functional. Nice grey anodizing here too.
  • Surprisingly light and small for a 21700 quad light.
  • No stepdowns due to thermals mean it stays bright for as long as possible but gets extremely hot.
  • Simple 4 mode interface, no strobe.

 

Con’s

  • In continuous output in maximum output this gets super hot, Up to 78.4C in uncooled runtime tests. This is too hot to hold safely, so run the light only as bright as you need or can stand.
  • The pocket clip is super stiff, it takes effort to clip onto your pocket.
  • Some rattle with the 18650 adapter but that is to be expected.

 

Conclusion

The full name of the light (Reylight Quad Emitter Dawn Custom Maratac LED Flashlight + Glow Afterburner) is lunacy, but the quality of the light makes up for it. For a 21700 sized light it was smaller than I thought it would be. The slimness of the tube really helps.

 

It’s not something I will carry often in my front pockets for EDC for office tasks but you could carry it pretty easily in a larger pocket or back pocket if you wanted. It’s not too big in a front pocket either if you wanted. For me it fits great in the hand and that is only made better with the dimples for grip. It’s a great walking the dog type of light, high at 1400 lumens and the floody beam is more then you need, and with 2+ hours of runtime it is plenty for most people. One more mode between low at 250 lumens and high at 1400 lumens would make it a little more useful I think.

That said on Turbo for continuous use this light is dangerously hot, 78.9C (174F) is burn you hot, that said you I only saw this at the 31 minute mark and I don’t think you will see it in the real world because a sane person would shut the light off or turn it way down as you wouldn’t be able to hold it. I don’t recommend running your light in turbo for so long because it’s not good for the battery either. 

Overall this is a nice light at a fair price. I enjoy it and am glad I have one. It’s easy to recommend and is a nice size too.

Packaging & Accessories

 The SP33 has a bit of a more retail looking box then we have seen from them in the past. It’s a black and orange hanger box but it doesn’t have a photo of the light on it, just a night shot showing a very bright flashlight. Accessories that are included with the SP33 V3 Kit are The 5500mAh 26650 battery, 18650 battery adapter tube, USB-A to C charging cable, manual, and a lanyard with a couple extra o’rings. 

 

Construction

The SP33 V3 is made of 6061 aluminum and hard anodized in black. Machining is good for the price range, with no major concerns. Starting at the tail cap, it has a crown and one side has 2 holes for a lanyard attachment point. They are just a little to small to easily fit paracord in, but you might be able to if you are patient and creative. Knurling is straight and there are a few flats in place for style. This is different from the rest of the light but provide function. Inside there is a single short fairly stiff spring that provides compatibility with the many different battery types this light supports. Threads are ACME cut and were dry in my example.

The body tube is reversible and has a decently thick walls. There isn’t a place for a clip but that’s ok for a light of this diameter in my opinion. The knurling is standard diamond knurling and is done in four panels around the light and is of medium texture.

The head is a solid piece. In the center you have the flat plastic e-switch button with an LED in the middle used for power indication. Around the hexagon there are small areas milled in to help with cooling and give style. Opposite the button is the USB-C port for recharging. The silicon cover here is a bit large and does protrude slightly from the lights back, enough so it won’t sit flat on this port but in the hand this works fine and stays out of the way.

The V3 features a deeper stainless steel bezel with a few short but long crenelations. This has been lengthened on the V3 version. The lens looks to be uncoated mineral glass and is fairly thick. The reflector underneath is deep with an orange peel.

 

Size & Weight

I measured the length of the light at 126mm, maximum diameter at 37.5mm, minimum diameter at 32mm. Weight with the included battery is 229g. 

I don’t have a lot of other great 26650 lights that are similar sized to compare it to. What I do have is the Wowtac A4 V2 I reviewed recently. It’s similar in length and diameter but the head is much larger. I also have the Sofirn SP36 I reviewed last year, its similar in length but has more diameter due to it’s 3 18650 batteries. 

Retention

Not much to say on retention here, there isn’t a place for a clip on the light, and it doesn’t come with a holster. The tail cap does have a place for a lanyard to attach if you wish. The light does tail stand without an issue.

 

LED & Beam Shots

V3 of this light is using a Cree XHP50.2 LED at 3V instead of the 6V version of this led. Tint is listed at between 6000-6500k, so cool white. On lower powers I do notice a bit of green tint shift on my example but it’s minimal. On higher powers you do notice tint shift across the beam. I would categorize the light as an all purpose beam, It’s fairly wide and the hotspot is so broad it’s not a thrower, yet it goes a good distance as you can see in my night shots. Sofirn quotes a throw of 275 meters and I think that’s a good number that’s in the ballpark.

V3 is using a FET driver instead of boost driver meaning it’s drawing more current from the battery thus the higher turbo output that’s seen here. You are going to want to use a good high quality high drain flat top battery with this light for maximum performance. It can accept 26650’s of all types, 18650’s of all types with the included spacer, or unprotected flat top 21700 batteries. The light has PWM on all modes according to my scope and solar cell setup. That said it’s pretty fast and my eyes or camera don’t notice it. 

 

Output is listed as:

  • Turbo 3500 Lumens
  • High 1600 Lumens
  • Medium 450 Lumens 
  • Low 150 Lumens
  • Moon 1 Lumen

 

Heat and Runtime

The SP33 V3 features Advanced temperature regulation without timed step downs, instead output will decline with the drivers internals reach 55C. Brightness will increase again when temps decrease, and we can see this in the runtime graph, as it’s a very seesaw motion. On average you’re seeing maybe a 20% swing in relative output over the life of the battery after the initial turbo step down. I didn’t notice it unless I was really focused on it on a 25 minute walk with the light. Turbo did start stepping down due to heat at 1 min 45 seconds, taking a little over a minute to step down to 18% relative output to cool. From here you can see on the graph it went up and down in terms of output as the flashlight regulated its own heat.

Total runtime on the included 5500mAh battery was 3:24:00. FL1 was at 3:11:00 and the maximum temp I saw during my runtime on the exterior was 48C or 118F so definitely very warm. All temps were taken at my ambient room temp of about 25C.

 

User Interface

 This light has 2 UI modes, default mode (mode 1) is a stepped mode that works logically. It has moonlight, low, medium, and high modes with memory and Turbo without. A single click turns the light on from off, and holding the button down cycles through modes. Long press when off turns on Moonlight mode and double click goes to Turbo. Triple click to go to SOS/blinking modes.

The second UI mode is a ramping mode. To switch between the 2 modes when the light is on do a quick quad press. Ramping is like many other ramping modes with a flash on both the top and bottom end. For me while I like being able to set brightness exactly where I want it, I don’t love the speed of the ramp here, it’s a little on the slow side. 

There is an electronic lockout when the light is off just quad click quickly. You can also mechanically lock it out with a slight twist of the tail or body tube. This is useful for such a powerful light os you don’t burn a hole in a bag or coat. 

 

Recharging

The light isn’t picky on the size of batteries used in the light diameter or size wise. It can accept 26650’s of all types, 18650’s of all types with the included spacer, or unprotected flat top 21700 batteries. The later having the most slop in the tube due to not including an appropriately sized spacer. I used the supplied 5500mAh Sofirn 26650 battery for my charging tests. LVP came in on the light at 2.895V, so a little lower then I prefer but acceptable. The battery measured as fully charged at 4.15V. 

The light does use USB-C for recharging which is nice to see. However it requires a USB-A to C cable (Supplied) to charge, and isn’t compatible with a C-C cable. When charging the small LED in the center of the button blinks red, and goes blue when charged. From LVP to full the light took 3 hours, 30 minutes. Maximum charging rate was 1.7A. 

 

Pro’s

  • Great budget friendly price for a lot of light in a good overall package.
  •  Is available in a few different versions, and battery options.
  •  UI is more “beginner friendly” than Anduril firmware.

 

 

Con’s

  • Still not fully utilizing USB-C to C, requires a USB-A to USB-C cable to recharge.
  • Very active thermal controls, with a good amount of change in output. 
  • No Neutral White tint option.

 

Conclusion

The Sofirn SP33 V3 is a low cost light with a lot of Output. Sofirn lists the light as making 3500 lumens. It runs on 26650, 18650 and some 21700 batteries so it’s widely compatible with the 3 most popular battery sizes today. 

 

It has features not usually found in this price category like USB-C charging (not compatible with USB-C PD (C-C) charging), active thermal controls, and a stainless steel bezel. The active Thermal controls are pretty reactive but they are smooth and I don’t notice it with my eye as much as the graph shows. I wish it was more widely available in Neutral white, they list it as an available option on their AliExpress store but I don’t see these available from other retailers. 

 

For the money especially with the discount Sofirn has provided makes this a really great value for the complete kit. It fits well in my hand and produces a ton of light. I can easily recommend this as a great high output budget light to pick up.

Packaging and Accessories

Packaging here is a nice high quality cardboard box with a picture of the light in front being part of the model number G15. The sides list the battery, capacity, and charging speed, and a highlight of the specs, including the 5 year warranty. On the back you have a more detailed spec chart and list of features. The light is IPX 8 water rated.

Included accessories are the Light itself, Klarus Branded 5000mAh button top protected 21700 battery. It’s listed as a 15A capable battery. The battery itself is long coming in at 74.7mm. Also included is a spare oring, Klarus branded lanyard, Felt pouch, manual and MicroUSB charging cable. 

 

Construction

The light is made from aluminum and anodized a smooth fairly glossy black. The tail is flat allowing for the light to tail stand, but it’s non magnetic. The tail has been cut on the side to allow for the lanyard to attach. The body and tail are all one piece, with the long clip only attaching on the rear section. It allows for deep carry and it’s fairly stiff. The milling on the body tube to provide texture looks like the profile for an involute gear and then has 6 flats milled into the light. I like the pattern here, it’s a little different, provides good grip without being too aggressive. The flashlight only disconnects between the head and the body. The threads are raw aluminum, and beefy square cut with grease.

 

 

The head features the same button we saw on ST15R and XT21X in 2019. It’s a silicone button with an illuminated sliver of light around it that indicates battery status and goes Green/Red/Yellow. There is minimal milling on the sides for heat dissipation. Opposite the button is the flush fitting silicone port to protect the MicroUSB charging port. It’s at a standard depth and there is plenty of clearance for larger cables to fit. The head has minimal branding and labels on it, and light bronze color. The front bezel is smooth, and it looks like it will unscrew with the right tool. The lens is anti reflective coated glass, surrounded by a deep orange peel reflector with the large XHP70.2 LED at the center.

 

Size & Weight

I measured overall length of the Klarus G15 at 122mm, maximum diameter in the head at 27.5mm between the button and the charging port, and minimum diameter on the body at 23.24 between flats. Weight with the included battery and clip is 142.1g. 

Looking through my light collection I don’t have a ton of 21700 sized lights that are super comparable here. Lights that I have that are similar are most often using an 18650 or end up being larger. I settled on comparing it to the Olight M2R Pro since they use the same battery and are physically similar. The Olight is a bit longer here, and heavier and is more tactical in nature. It’s also more of a thrower where the G15 is more about flood. 

 

LED | Beamshot | Runtime

The Klarus G15 is using the Cree XHP 70.2 LED in a cool white 6500k tint. Being a 70.2 LED there is tint shift across the beam but it’s not as dramatic as I have seen from a few other lights. There is a slight increase in intensity in the center but this is more of a flood style light then a thrower. The spill is very wide and fades into nothing without a cutoff. 

Mode Spacing here as you can see in the table below is ok but could be improved. There is quite a bit of difference to the eye between medium at 500 lumens and high at 2000 lumens. An additional mode in between would be nice. That said to the eye here is a difference between high at 2000 lumens and Turbo at 4000 but it’s not nearly as much as you might think.

My runtime’s didn’t match Klarus’s all that well. For my first runtime test I started the light on Turbo uncooled and the light steps down pretty aggressively quite quickly about 4 minutes before starting a seasaw motion as the light heated up, and them stepped down to cool off but then what was nice is that it went brighter again as thermals and battery power allowed. The average output for the first hour was somewhere around 60% relative output. The next hour was very stable at about 45% output, before the light started to step down slowly and small bumps at first before LVP kicked in at about 185 minutes of total runtime. Other major manufactures, namely Olight have started to be very honest about what their high lumen lights can do before stepdown and I believe Klarus should do this as well, it would be more honest then to suggest their lights can do 1.2 hours on turbo or 1.5 hours on high. Reality is no light can do this but it’s not obvious to non flashaholics. 

Overall heat was well managed with the active thermal controls here. At 1 minute I measured 92F, at 2 minutes at 98F, and at 10 minutes I measured 96F. LVP kicked in at 2.688v which is lower then I would like to see. 

 

UI

UI here is simple and straightforward and it has 8 total output modes. 5 of those modes are constant on, and 3 are forms of blinking. From off, long press on the button to get to moonlight mode at 1 lumen. Press again and hold to get to low, keep pressing to cycle through low, medium and high. Double click to go to turbo. Tripple click to go to the blinking modes. 

 

The light also features memory mode for modes other then turbo, moonlight, or the strobes. It also had lockout mode, but I personally just break contact with the battery as it’s easier and faster. 

 

Recharging

The light recharges with a standard MicroUSB cable, this is a little frustrating given the price of the light and that it’s a new release for 2020 where USB-C should be the standard. I recharged the included 5000mAh battery from LVP at 2.825V to Full at 4.13v in 3 hours and 35 minutes with a maximum charging speed of 1.99A. As the battery capacity filled up charging slowed down as expected. I saw no problems with the built in recharging on this light. 

 

 

Pro’s

  • Compact size for a 21700, nice fit and finish
  • I enjoy the new gear tooth milling in the body
  • Easy interface
  • Active thermal controls.

 

Con’s

  • MicroUSB instead of USB-C, at least the charging speed here is fast at 2A
  • Pretty cool LED tint with some of the characteristic XPH 70.2 tint shift across the beam

 

Conclusion

If you are looking for a compact 21700 style EDC flood light with an electronic switch up front, the G15 could be a good choice for you. It was a surprise to see active thermal management here that allowed the light to get brighter again after step down after it cooled off. Not enough lights do this in my opinion. I like the new texture here on the body of the light, hopefully it’s something that stays, I think it’s just about perfect for EDC, not too much to rip up your hand or pocket but definitely better than standard diamond knurling. 4000 Lumen turbo mode here isn’t quite as impressive as the numbers suggest, it’s not significantly different from the high of 2000 lumens. That said it’s really a light that’s best run on the lower output modes anyways for a more useful runtime. Hopefully in 2020 we see Klarus switching to USB-C (That support USB-C to C) in their higher priced lights and we can be hopeful that we will see something other then cool white too for us enthusiasts like myself that prefer warmer and neutral tints. With all that said I can recommend the Klarus G15 with reservations.
