Today I have for review a light I’ve been excited about since I first reported about it in the PhreakyBriefing, another site I write for. Subscribe to that mail here!
This is the Thrunite T2, a bigger version but very similar to the Thrunite T1. The T2 is a 21700 indicating e-switch light, with USB-C charging, and a Cree XHP70.2 emitter. It’s a bit of a beast!
Official Specs and Features
There’s only one body, but it’s available with both CW and NW (seen here) temperature Cree XHP70.2 emitter. With the T1, we ended up seeing other body colors – maybe we’ll see that here too.
These list for (what I consider) the very reasonable price of $79.95.
And on amazon right now it’s $10 off! Get to amazon here (referral link), for $69.95$
It’s really a beast. The output is incredible – the NW light meets the output spec (which is almost certainly written for the CW version!). A cell is included (aka “complete package”). USB-C charging at 2A is fantastic. All in all I think this is a great package light

- Measurement disclaimer: I am an amateur flashlight reviewer. I don’t have $10,000 or even $1,000 worth of testing equipment. I test output and such in PVC tubes!! Please consider claims within 10% of what I measure to be perfectly reasonable (accurate, even).

- Nylon pouch
- Spare o-rings (2)

Package and Manual
Build Quality and Disassembly
Thrunite’s build quality is great. Also this light is a bit of a chunk in hand – remember it’s a 21700 light (not 18650!). So the step up from the T1 (which was 18350) to the T2 completely skips the 18650 size. (Note that the 18650 size is essentially captured in the Wowtac A6 light, though).
The size and shape (and of course the overall build quality) of this light somehow appeals to me. It lacks the “flashlightyness” of a larger head, but it still fits that niche for me.
The head has minimal depth cooling fins.
The body doesn’t have knurling, but has ridges which provide grip. I believe this also adds to the overall higher build quality feel of the T2.
The charge port cover is very well fit into the charge port opening.
The threads on the head end are square cut, very smooth, and not too long. It is difficult to remove the head without clicking the switch, but that’s just something you’ll have to deal with.
The tail has a nice big spring. The head has only a brass button contact.
This button is quite long, though.
That button is necessary for fitting the Thrunite proprietary cell. More on this cell later.

Size and Comps
Officially: 112mm x 30.5mm x 26mm
Weight: 87g (excluding battery)
Retention and Carry
Thrunite provides a nice nylon pouch. The T2 will fit in either orientation, and there are no holes in the top or bottom for use while in the pouch.
Also included (and installed) is a two-way deep carry friction fit pocket clip. The clip is not reversible and can only go on the tail, but again, it’s a two-way clip. Bezel down the light is flush with the pocket. Bezel up, there’s around 1.5″ out of the pocket. (To wit, there’s no good reason to bother with a two-way clip here, since so much will stick out of the pocket in a bezel-up carry.)
Also included is a standard lanyard, which attaches through a hole in the tailcap.
Because of the clip setup, the light could reasonably be used on the bill of a cap (“hatlight”) but overall the light is probably too heavy to do this very well. But it would work.
Power and Runtime
The T2 is powered by a single lithium ion cell. One is provided, seen below. It’s a 5000mAh 21700, with proprietary connection on the positive end. This connection has both positive and negative terminals. See below but read now: there’s actually no reason for these proprietary connections!
If you wish to use your own 21700 cell, you may do so (it’ll work!) and charging will also work! You might have to lengthen your standard (flat top) 21700 in some way, though (I tested with two thin magnets, around 2-3mm total).
Below see the plastic shroud around the positive terminal.
And below a better view of the positive (center) and negative (surrounding positive) terminals on the proprietary, along with the standard negative on the end opposite positive.
The cell fits with the positive end toward the head (which is the normal configuration).
Runtimes can be seen below. Turbo was claimed at 2 minutes for the high output with a stepdown to around 725 lumens. I see the stepdown at around 1 minute, but the stepdown is to much higher than 725 – around 1450 lumens. And the 1450 lumens last very stably for around 1.5 hours. This is extremely respectable output!
High maintains for well over an hour at nearly-initial output. Again, extremely respectable. The light does get warm (hot? maybe), but you have to expect it.
Medium is again remarkably stable – greater than 400 lumens for over 7 hours. 7.5 hours is the claim, and this is very very close. Actually the dropoff happens at 449 minutes – 450 minutes = 7.5 hours. So the medium runtime test is one minute under the claim (something like a fifth of a percent off the claim). This is good performance. (It’s also noticeably over the 366 lumen claim, too!)
The light does exhibit low voltage protection, around. 2.8-2.9V. Even before that the indicating switch will turn red, then blink red to alert the user.
On bench power, the switch warning starts at about 2.6V, and then the light switches off.
Also built into the T2 is USB-C charging. The port is in the head (opposite the switch) and has a press-in rubber cover (there is a spare). This is a high quality port – something I don’t say all that often because it’s not always so evident. The port lines up perfectly with the opening.
There’s also a cable included for charging – USB to USB-C.
Charging proceeds at around 2A (just over, really) and it’s so absolutely consistent that below is actually two charge graphs but just looks like one! They match perfectly. Charging is very good.
Charging USB-C to USB-C does work just fine, but it’s charges only at 5V (not power delivery of 9V or 12V or whatever.)
Modes and Currents
|Mode||Mode Claimed Output (lm)||Claimed Runtime||Measured Lumens||Tailcap Amps|
Pulse Width Modulation
There’s no PWM on any mode.
For reference, here’s a baseline shot, with all the room lights off and almost nothing hitting the sensor. And here’s the worst PWM light I have ever owned. Also one of the very first lights I ordered directly from China!
User Interface and Operation
The T2 has a single switch. It’s an indicating e-switch on the head, and just slightly proud. The cover is hard (but probably plastic not metal) – still a great switch. It’s easy to differentiate between the switch and the charge port cover.
Indication is seen in blue below, but the switch can also indicate red, and “purple” (red and blue switching very fast.)
Here’s a UI table!
|Off||Click||On (Mode Memory except Firefly, Turbo, Strobe)|
|Lockout||Click||No Output (switch indicates red)|
|On (Except Firefly)||Hold||Mode advance (LMH only)|
This is the same UI as other Thrunites. The T1, for example.
LED and Beam
The emitter in the T2 is a Cree XHP70.2. Seems like all the documentation says it’s XHP70, but clearly it’s 70.2 (see photo below). The reflector is a very shallow, lightly orange peel reflector. You’d expect it to be largely flood, and it is, but there’s still a hotspot.
These beamshots are always with the following settings: f8, ISO100, 0.3s shutter, and manual 5000K exposure.
Tint vs BLF-348 (KillzoneFlashlights.com 219b version) (affiliate link)
I keep the test flashlight on the left, and the BLF-348 reference flashlight on the right.
I compare everything to the KillzoneFlashlights.com 219b BLF-348 because it’s inexpensive and has the best tint!
What I like
- Complete package light
- Indicating e-switch
- UI consistency with other Thrunites
- Excellently stable output
- High build quality standard
- NW offered as well as CW
What I don’t like
- Can’t see any good reason to include a proprietary cell
