[Liquidretro Reviews] Thrunite T2 (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.

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 charger and work just fine.

Cons

  • Not USB-C to C Compliant, no USB-C PD support. It requires a USB-A to C cable (Included) to recharge.
  • 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.

Nice review.
The light really needs a mode of about 700lm, that can be sustained without stepping down.
All the Best,
Jeff

Thanks for the review. It’s likely the most efficient single cell light I’ve seen.

I like how super efficient this light is from the reviews I've seen but the light color is horribly green. The DUV is greater than 0.01!!! This is the NW version. Maybe the CW might be less green.

Absolutely!!
Going from 366 to 1700 is poor spacing. Looks like a great light in all other ways. 700 lumen for a solid 4 hours would be great and highly useful.

Was ready to buy until I saw this.

I’d have liked to see it compared to a ZL SC700d – especially given the 90cri used in the Zebralight
