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.

Thrunite T2 Review (3757 Lumens, XHP 70 LED, USB-C, 21700)

Today I am taking a look at Thrunite’s newest model, the T2. It’s super floody light, producing a whopping 3757 lumens out of a Cree XHP 70 LED, a 21700 battery, and is rechargeable with onboard USB-C. Thanks to Thrunite for sending it to me to review. Let’s take a closer look. Be sure to see Thrunite’s deal on the bottom of the page for the T2.

Packaging and Accessories

Packaging here is Thrunites standard good quality brown cardboard box with minimal information. The side lists the model and emitter. Inside the light is protected well with foam. Accessories include the light, a 5000mAh Thrunite branded button top 21700 battery, a nylon holster, USB-A to C charging cable, 2 extra orings, a spare charging port cover and a branded lanyard along with a manual. 

 

Construction

The T2 shares many similar visual features to the smaller Thrunite T1 I reviewed earlier this year. The T2 is made from 6061 aluminum and has a fairly flat tail cap, that is non magnetic, but has a place milled in the side for a lanyard. The tail section and body are a one piece design. The clip only attaches at the tail and is non captured. The body section has a rectangle/rib pattern milled in oti. It’s similar to the Olight M2R which is a competitor light. The T2’s millings are deeper and the rectangle sections are a little larger. It’s a nice amount of grip.

Threads on the body tube are anodized, square cut and nicely greased. Inside the head it has a single brass post up front to fit the proprietary battery. On the outside there is a silver metallic button covering the eswitch with a hole in the middle for the LED indicator. The sides have some milled fins in them. Opposite the button is the silicone cover for the USB-C charging port. I had no trouble here with access to any of the cables I tried. The port is nicely recessed and out of the way.

The aluminum bezel has a grey accent that’s slightly tapered. Inside is a AR coated piece of glass, a wide but very shallow orange peel reflector and the giant Cree XHP 70 LED. 

 

Size & Weight

I measured the length at 112mm and maximum diameter on the head at 30mm and minimum diameter on the body at 26mm. Weight with the included battery and clip was 167.8g. 

 

Comparison

The light that i will be comparing this to is the Olight M2R. Now the M2R is a little more tactically focused but quite similar in over all size. The T2 is shorter in overall size and hardly grows in diameter. That said the M2R does have a bit more reach. The T2 seems to sacrifice it’s throw performance for the overall length of the light in the hand.

Retention

The T2 comes with a basic nylon holster, with a Dring and belt loop. The T2 fits inside just fine. You also have the option of a branded lanyard. These are basic options but do the job just fine. The T2 has as very deep carry pocket clip that only attaches at the tail of the light. It bends out and then up almost flush with the tail but on my example here that upper loop is hard to attach onto a pocket due to the step and small amount of space up top. Other than that it’s a decent clip and once you get it down over your pocket lip it carries well for a 21700 light.

LED & Beamshots

The Thrunite T2 is running a Cree XHP 70 LED and is a available in cool and neutral white. I have the neutral white and it has a bit fo green to it, not uncommon for a Cree emitter. It’s a big LED in a very short and wide reflector. The result is a very floody beam with a good amount of tint shift unfortunately. At 

When the light is dropped on it’s tail it flickers slightly but stays on. I didn’t detect any PWM with my oscilloscope. 

Official Outputs are listed as the following.

  • Firefly  – 0.3 Lumens
  • Low – 30 Lumens
  • Medium – 366 Lumens
  • High – 1712 Lumens
  • Turbo – 3757 Lumens

 

Heat & Runtime

With big output numbers from a big LED comes heat and output stepdowns. Turbo on the T2 started to step down at 1:10 and then ran at 38% relative output till the 8 minute mark, stepping down another 10%. FL1 was at 3 hours 12 minutes. Total runtime was 3hr 20 minutes. Peak heat was 49.9C at 1:30

I did a bit of comparison to the Olight M2R Pro also running a 5000mAh 21700 battery and you can see the Olight has a little brighter mid range but ends about 5 minutes shorter. Overall both lights are pretty comparable in terms of runtime even though their beam patterns are really used for different purposes. 

 

UI

The UI on the T2 is what Thrunite uses on most Thrunite and Wowtac models. Long press to go to Firefly, single click to go up in modes from L, M, H, and double press to go to Turbo. Triple press to go to strobe. There is a memory mode on all normal modes, and a lock out if you press and hold while the flashlight is off. Mode spacing here could be improved, with just 3 modes you see some big steps up, Medium to High is 366 to 1712. I would like to see another mode in the middle.

 

It’s kind of a bit of a shame they didn’t decide to use the T1’s ramping mode as I liked that quite a bit. For a more high end light like this, it’s almost becoming the norm to have a stepped and ramping mode that the user can switch in and out of. 

 

Recharging

The Thrunite T2 has onboard USB-C recharging, and it ships with an A to C cable. They advertise the light as having fast charging but doesn’t really say what that is. I had my hopes up that it would be compatible with C to C  charging via USB-C PD but at least in my testing that doesn’t seem to be the case. Charging the 5000mAh battery from LVP at 2.948V to Full at 4.199V took 3 hours 30 minutes. Maximum charging rate I saw was right at 2A. It didn’t ramp up but instead started right at 2A and then ramped down as the battery filled. The LED Indicator on the button displays power levels in real time. Greater then 21% is blue, between 11-20% red, and flashing red is less then 10% power remaining. When charging they go red and then blue when charged.

I was a little worried about the included 5000mAh battery as it has both the positive and negative terminals on the positive side, it looks identical to the battery Olight uses in the M2R Pro and in fact the Olight and Thrunite batteries are interchangeable in either light. What’s a little strange here is that Thrunite doesn’t have a contact point in the head for that negative terminal on the top of the battery so a standard button top 21700 works and charges in this light just fine. 

 

Pro’s

  • Compact High Lumen Flood
  • Neutral white tint is available
  • Even though it looks like a proprietary battery, standard batteries charge and work just fine.

 

Cons

  • Not USB-C to C Compliant, no USB-C PD support
  • Pocket clip need a little bit of tweaking to fit most pants for deep carry
  • Mode spacing is spaced out quite a bit. 0.3, 30, 366, 1712, 3757 lumens. 
  • Timed Step Down

 

Conclusion

The T2 a pretty good all around floody light with a lot of output from it’s Cree XHP 70 LED. It’s nice to see Thrunite continue to offer tint options on their lights. I find the overall design here a little boring to look at but in this case it’s form over function and functionally it’s pretty good. 

 

I would make a few small changes on a revised model if I could, another mode between medium and high to split the difference between 366 lumens and 1712 lumens. I would tweak the top loop of the clip to allow for it to fit over thicker pants easier, and I would make it compatible with a USB-C to C cable so it could be charged with many laptop and smartphone chargers. The USB-C to C cable is the one universal cable to make your life easier, we are just not there yet with most flashlights. It would be nice to see active thermal management on a light in this price range instead of a timed step down.

 

The battery here is really interesting, that Thrunite went to the expense of putting that negative contact on the positive end but doesn’t use it on this light. It makes me wonder what they might have coming out in the future. It’s nice here that you don’t need a proprietary battery though. 

 

Overall I can recommend the T2 if you need a high output flood light in a small package with a choice of tint. It even EDC’s and carries in a front pocket pretty well which I was not expecting for a 21700 light.
