Thrunite TH10 V2 Flashlight Review

The Thrunite TH10 V2 flashlight is more of a headlamp that runs on a single 18650 cell. The emitter is a Cree XHP35 HI, and is neutral white!

Official Specs and Features

Here’s a link to the Thrunite TH10 V2 Flashlight product page.

Versions

There are two versions of this headlamp. An NW (seen here) and a CW.

Price and Coupon

Currently, the price on Thrunite’s official site is $59.99. Typically there’s a 5% off if the item is purchased through Thrunite.com.

Short Review

This is an impressive headlamp that outputs over 2000 lumens and gets quite warm doing so. The built-in charging is a nice touch, and the included cell make this a very good package overall.

^ 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

The light ships in Thrunite’s standard cardboard box.

The manual is normal Thrunite level of quality. Most of the information is covered on the product page. (I’ll include a photo of the manual here later.)

Build Quality and Disassembly

This is a robust headlamp, and well built. There’s no slop in any part, and the feel in hand is one of quality.

The grip area is not huge (that is, it doesn’t cover more than half the body) but it’s comfortable to hold and doesn’t interfere with the silicone bit for the headband. The head does not have proper fins for cooling (as the TH30 does, for example), even though this light produces ample heat.

Here are the parts as broken down as I got them. The head and tail come off the cell tube. The bezel looks to be screwed in and could be removed with the proper spanner type tool. The anodizing is a little thin – the pocket clip has scuffed the cell tube after minimal twisting and turning.

The tailcap doesn’t have much grip; certainly no reeding or knurling. But it’s not difficult to unscrew the tailcap. My copy of this light had minimal lube (ie, “just the right amount”) and the anodized square-cut threads are very smooth.

The cell tube is not reversible. In fact, the head end has a much larger diameter, and the threads are unanodized. Fortunately, the anodized tail end threads allow mechanical lockout with a very short twist of the tailcap.

Size and Comps

This isn’t a small light, per se, but even with built-in charging, it ends up being a good bit shorter than the Convoy S2+.

And one more comparison, that I only made after the official shots were taken: Yes, this light has practically the same host as the TH30. There are a few updates, but essentially the light is the same. Between the two, I’d guess the TH30 would handle heat better, and the tailcap has a better grip for unscrewing the light, but such are advancements, I suppose. Granted, they’re different lights – the TH30 is more of a “wall of light” whereas the Th10 V2 is built for a more throwy beam. They make a great set, to be sure. (And you won’t confuse them in hand.)

Retention and Carry

Of course, the main means to carry this light is the headband. I never wear this type of light that way (though I did for testing, and can say it works very comfortably). My main means of carrying this light was the pocket clip. The clip attaches to the head or tail end of the light. On the head end, around 1.5″ of light sticks out of a pocket. The tail option allows for a much deeper carry but still reveals around 0.75″. The clip is not deep carry and is a snug friction fit clip.

A note here since where else should I put this? The light will “head” stand but the button sticks out just a little (maybe 0.5mm), so the light wobbles ever so slightly.

Power and Runtime

The TH10 V2 is powered by a single 18650, and Thrunite includes one. This, like with other Thrunites, is a Thrunite wrapped and protected Samsung 30Q. These are great cells. The included cell is a 3100mAh button top.

Initial output on Turbo is quite impressive at over 2150 lumens. At 30s, the output is slightly less than (but within the margin of error) of the claimed 2100 lumens (at 2000 lumens). The stepdown after 40s or so is fairly heavy, from ~2000 to ~650. Output from there is very stable, with a low temperature, too. When the cell gets low, the switch indicates by turning red, and the main emitter begins to flash on and off (as can be seen in the graph below). The light shuts off fully at around 3V.

High is similar, except that the output remains stable for much longer (10 minutes or so), then steps down only minimally to ~830 lumens. Overall this drives the light slightly harder on average, so the runtime is less. This runtime exhibited the same LVP.

Charging

Built into the head is a micro-USB charge port. A charging cable is included. The charge port cover fits quite snugly (and there is a spare included).

Here’s a charge graph from two charge events. They’re respectably similar, and charge from ~1.2A to ~1.5A during the CC phase. Charging takes around 2.5 hours.

This is a good charge cycle.

User Interface and Operation

The TH10 V2 has a single switch on the head. It’s an e-switch, with two indicating emitters; red and blue. The switch is held in place by a bezel I couldn’t remove (not sure if it’s screwed in or press-fit, but there are no reliefs, so it’s likely press-fit) This might not seem like a big deal but have a look at it below. It’s very smooth and great for button-pressing-comfort.

Here’s a user interface table! (It’s exactly like the TH30!)

State	Action	Result
Off	Click	On (Mode Memory except Firefly, Turbo, and SOS)
Off	Hold	Firefly
Any	Double Click	Turbo
On	Hold	Mode Advance (LMH>SOS direction) (No Firefly, no Turbo)

There is no strobe!

LED and Beam

The emitter used in this light is a Cree XHP35 HI, and my sample is NW. A CW is also available. The reflector is smooth and deep, and gives a very spotted beam, with little (but noticeable) spill. This is a great counterpoint to the TH30, which I already mentioned has the same body.

Low is respectably low, something I appreciate.

Random Comparisons and Competitive Options

My good friend u/parametrek tells me (at least through his site) that there’s really nothing else out there like this light. It’s the only single 18650 XHP35 HI headlamp with integrated charging.

So if that’s your need, then this light is perfect. I’ll add that at the cost of $60, this is a respectable deal, too.

Conclusion

What I like

Nice to see a tight beam in a headlamp
The NW option is good and while it looks green in the comparison, it’s not bad in person
Charging is good
Cell included is a 30Q, a cell I’m very fond of

What I don’t like

Thin anodizing
Top strap on headband isn’t removable
