So I see there really isn’t a ton about the TH10 on here, so I wanted to share my torture test and review
as well as post some additional testing that I’ve done on the light

alright… so lets talk about this light:
SPECS:

Testing:
The results are pretty explanatory. I ran this test using a Samsung 30Q 3000 mah and checked lux using a cell phone app at 1 meter every 20 minutes until the light stopped. You can see that the brightness gradually drops throughout the entire length of the test. at 126 minutes the light started blinking and I ended the test. End voltage was 2.89v I specifically used an unprotected battery to verify the LVP is working with the light.
tailcap readings:
.03 / .38 / 1.58 / 2.02 A
These were taking with a HF DMM with crummy leads

Construction:*
pre-torture
post-torture:
The construction is interesting. It has springs at both end of the battery tube. so it utilizes a separation in the battery tube to set up positive and negative. The positive end uses a wire that leads up to the switch and then to the led. The negative then just grounds out to the other side of the flashlight body which reaches the negative pole on the far side. The LED sits on an integral shelf which helps with heat dissipation.
The genius of the design is that the battery is perpendicular to the light. So if you are bouncing or dropping the light, you don’t have the battery smashing into any wiring or electronics. Furthermore, the path going from positive to the switch is very short, and switch to the led also very short. The wires have nothing to bang against and little room for them to move.
the metal switch is floating under a retaining ring so the torture test had no effect on it whatsoever. Even though I didn’t picture if there appears to be a rubber boot over the switch to help with waterproofing.
The driver is not exposed in this light. Not sure how they even got it in there? the LED sits on a shelf, and there is only one red wire going from the battery compartment to the switch. I’m assuming there is a small drive that is either attached to the switch, or placed in via the switch hole before the switch is installed. Not quite sure.
Performance:
I got a good 2 hours 6 minutes out of this light. Towards the end it was more like 200 lumens, but still very usable right to the very end. If you were using a Thrunite ncr18650b (rewrapped panasonic) your run time would easily be a bit longer. Thrunite advertises 118 minutes on this light, so your going to beat the factory specs. This head lamp does get pretty hot from about 10 minutes to 20 minutes and cools down to just warm after that. At the 10 minute mark it is uncomfortable to hold in your hand, but not bothersome if you are wearing it as a headlamp.
The beam has a nice little hotspot and lots of spill. I was able to see around 100 meters with it in the backyard.
The user interface is pretty simple. Just a click to turn on, click to turn off. Hold the click to change modes, and a double click to go into turbo, and a second double click for strobe.
Conclusion:
as you can see from the video, this light is about as tough as it gets. Performance was great, and the light can be run straight for 2 hours without it getting too hot to handle. it isn’t going to be very mod-able, but for a good rock solid head lamp your going to struggle to find something better for cheaper.
