Thrunite TW10 Flashlight Review
The Thrunite TW10 flashlight is a new weapon-mounted light that offers built-in USB-C charging, dual e-switches, and one straightforward mode. Read on for testing!
Official Specs and Features
Here’s a link to the Thrunite TW10 Flashlight product page.
Versions
I believe only black is available currently. The site has a neutral white option listed, but I don’t expect it to ever be available.
Thrunite TW10 Flashlight Price
Currently, on sale, the Thrunite TW10 flashlight is $50.35. And actually, on amazon, you can get 20% off the list price of $55 – so that puts this light in the $44 range! Here’s an Amazon referral link to the Thrunite TW10.
Short Review
I’m not a big shooter, so I’m testing this mostly from the perspective of a flashlight. As a one-mode light, this is pretty great. If that’s what you need on your weapon, then I can say the user interface on this one is good, and it seems reliable.

^ Measurement disclaimer: Testing flashlights is my hobby. I use hobbyist-level equipment for testing, including some I made myself. Try not to get buried in the details of manufacturer specifications versus measurements recorded here; A certain amount of difference (say, 10 or 15%) is perfectly reasonable.

Package and Manual
Build Quality and Disassembly
Another Black Scout Survival light by Thrunite! This weapon-mounted light has a no-tool mounting system.
Below you can see the head removed. Only the head comes off. The head has a spring, which contacts the negative terminal of the cell! On the other end (which I managed to not photograph, sorry), there are two springs – one is for negative contact, one for positive. More on all that later.
Size and Comps
Officially: 77mm x 26mm x 32.5mm, and 78g in weight.
If the flashlight will headstand, I’ll show it here (usually the third photo). If the flashlight will tailstand, I’ll show that here, too (usually the fourth photo).
Here’s the test light with the venerable Convoy S2+. Mine is a custom “baked” edition Nichia 219b triple. A very nice 18650 light!
And here’s the light beside my custom-engraved TorchLAB BOSS 35, an 18350 light. I reviewed the aluminum version of that light in both 35 and 70 formats.
Retention and Carry
The Thrunite TW10 flashlight is essentially only a weapon-mounted light.
The mount is for mounting on rails, and two types of adapters are included. Below, you can see the 1913 style, but also included is a GL type. The GL ships installed. A hex tool is required for swapping this part, and that is included too. There are even two spare screws!
Below are just some random mount photos – you’re probably not throwing this on your AR-style weapon, but it’d be reasonably possible I think.
Something that positively chaps my hide is that Nerf rails are not standard dimensions. So while this Thrunite TW10 flashlight looks mounted, it’s not really mounted well. (Again, not that you’d really mount this way on any gun.) I really wish Nerf rails were standard rails!!
There’s nothing else for carrying the Thrunite TW10 flashlight.
Power and Runtime
The Thrunite TW10 flashlight is powered by a single lithium-ion cell. One is provided, seen below. It’s a 1100mAh 18350, with a proprietary connection on the positive end. This connection has both positive and negative terminals. Unlike some previous Thrunites which carried this cell, on the Thrunite TW10, this cell with these specialty connections is required.
And below is 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.
Be careful here, because the cell goes into the TW10 in the unusual way – negative terminal toward the head.
There’s just one mode, so I did testing cooled and uncooled. Initial output isn’t that different, but the stepdown output is markedly different.
A low voltage warning is given by a red indicator beside the charge port. It is possible to loosen the head just a tiny bit and mechanically lockout the light.
Charging
Also built into the Thrunite TW10 flashlight is USB-C charging. The port is in the tail and has a press-in clear 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.
The graph below shows two types of charging. Solid line is USB to USB-C (which is the “intended” type since that’s the cable Thrunite includes). The dashed lines are USB-C to USB-C charging.
Modes and Currents
| Mode | Mode Claimed Output (lm) | Claimed Runtime | Measured Lumens | Tailcap Amps |
|---|---|---|---|---|
| On | 900/427 | 195s/135m | 851 | 7.35 |
Pulse Width Modulation
The single mode does not utilize PWM.
Here you can see a “baseline” – a chart with almost no light hitting the sensor.
Then there’s the Ultrafire WF-602C flashlight, which has some of the worst PWM I’ve seen. It’s so bad that I used a post about it to explain PWM! Here are multiple timescales (10ms, 5ms, 2ms, 1ms, 0.5ms, 0.2ms) to make comparing this “worst” PWM light to the test light easier. That post also explains why I didn’t test the WF-602C at the usual 50us scale.
User Interface and Operation
There are more switches on the Thrunite TW10 flashlight than there are modes – two switches on the tail are available for ambidextrous use, and either-handed shooting orientation.
The switches do the same thing exactly and don’t control any different aspects. It’s possible to turn on with one switch and turn off with the other.
The action is very low and the switch is very positive. It’s also…. a little loud – so bear that mind if you do a lot of sneaking around with your gun drawn.
Here’s a user interface table!
| State | Action | Result |
|---|---|---|
| Off | Click | On |
| On | Click | Off |
| Off | Hold | Momentary |
LED and Beam
Thrunite states this emitter as an Osram P9. It’s also cool white.
A neutral white option is mentioned on the website but Thrunite has been doing that for a while and never actually offering nw. So we’ll see.
These beamshots always have the following settings: f8, ISO100, 0.3s shutter, and manual 5000K exposure. These photos are taken at floor level, and the beam hits the ceiling around 9 feet away.
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!
