Nice and bright with removable, replaceable battery
This was a bit expensive imho compared to their other lights but I needed it quickly and cheaper lights would not arrive on time for me. I was very happy with the brightness and adjustment and was very happy to find the battery is replaceable and interchangeable. This made sure with the purchase of a few extra batteries w/charger that I was going into the woods with a full battery without leaving the light itself on charge. Pretty happy with my purchase so far

BRIGHT light, sturdy and easy to use
We use this light for hog/varmint hunting in low light/dark. Battery charges a little slow but with a large single battery I can't complain. I have not, however found a replacement battery to buy to always have a fresh one on hand... Either way, small enough to fit in your pocket and designed with a wrist loop and push button. I do wish it was quieter to click on but beggars can't be choosers I suppose. Easy to use, feels sturdy built, BRIGHT light that you can flood a large area or narrow it down to a clearer small area. Long range light as well

Great upgrade for ATN 4K IR torch
I replaced my IR torch (850 nm) on my ATN 4K scope because image was poorly illuminated. I added this 940nm torch and instant image clarity and detail. Half the weight of the previous light. Focus and installation are easy. Much improved. Mount is solid and aligns well. Switch is crisp and definite. Would recommend for sure.

Good 850nm IR, with some caveats
This is for the 850nm, IR flashlight. This is NOT a visible light to an unaided eye. 850nm infrared is optimal for viewing through night vision. This is being used with a PVS-14 with an NNVT photo-multiplier tube. The beam is entirely invisible to an unaided eye, but very bright through the PVS14. Switching the light on, even with sensitivity reduced on the PVS-14 is sufficient to initiate momentary flash-protection. Outdoors, the wide beam gives fairly bright illumination through the PVS-14 out to around a hundred feet. The focused beam doubles that. However, it's possible to pass through a point of focus on the diode, which can produce an artifact in the beam. Looking toward the beam, the IR diode is visible to an unaided eye when the flashlight is on, but it's not especially bright. A red filter on the lens can reduce this. And a warning, I don't recommend looking directly into the beam as night-dilated pupils will be allowing the full brightness of the invisible IR to enter your eyes. A 940nm diode should be somewhat less visible when on, though just as bright; but 940nm IR light is also toward the edge of sensitivity for light amplifiers and IR cameras. The flashlight came with an 18650 "Li-ion" battery rated at 2,000 mAh manufactured by Tianyida Electronic Technology Co., Ltd, and branded "DarkBeam". I couldn't come up a chemistry on the battery, so I'm assuming it's a Lithium Cobalt of some type, which suggests handling it with care. It also included a rather sketchy charger with a USB-C port and a warning not to exceed 2-Amp charging. I charged the battery (I think... the indicator light on the charger was intermittent) outside, on concrete, and using a 1-Amp USB supply. I recommend removing the battery from the flashlight when it's not in use. The flashlight has no unaided eye "ON" indicator, other than looking toward the emitter diode to see if it's glowing. Consequently, it's possible to leave the flashlight activated without realizing it. An indicator light or some type of obvious lockout mechanism would be better than the toggling button switch. For the price, it's pretty good. Just use it with caution.

best option for price
Great IR assistant to any IR lens or camera, and while it doesn't feel super sturdy, I haven't had any issues with it breaking or wearing faster than it should.

Low battery life
I received the light charged it had a really good light beam. Got up the next morning and got halfway to my stand and the light went out. I got home charged the battery again had the same result, works great for a few minutes then it’s over. Not happy at all

Excellent
Really nice budget hunting light. Beam is a nice saturated red and not orange or "pinkish" like you get with filters. This is a true red diode. Comes with a nice little carrying case and an 18560 battery. The best feature of this light is that it has an adjustable/zoomable lens that allows you to concentrate the light into a compact tight spot, or back it off to use it as a wide field flood light. A lot of hunting lights don't have this feature for some reason, especially the more expensive ones. Another nice thing about this kit is that it's compatible with some of the Feyachi pressure switches and mounts. So if you have one of their white lights and want red or green you grab this light and use it with their accessories. Overall I am quite happy with this. It's not the brightest light, but for the price it's hard to beat the quality and features.
