940nm IR Flashlight Infrared Illuminator Flashlight, 940nm IR Illuminator Flashlight Night Vision Flashlight, 940nm Infrared Flashlight for Hunting, Night Vision Camera

Works great with night vission cameras or googles

It fills a spot between admin light and weapon light/illuminator. It does a good job illuminating "enough" without actually auto-gating the tube much, if at all. Definitely not bright enough for anything but gen 3, and maybe gen 2+. Expect a realistic maximum of around 25 yards at wide focus and maybe 90 yards at narrow focus if there is any ambient light at all, after that it just blends in with starlight on a clear day. It does not defeat photonic barriers whatsoever, but it won't auto-gate your tube much (if any) either.

Battery is non regular type costing as much as the light infuriating

Not bad for the price. Used on my HHV helmet for ir illumination with nods. Flood to about 25 yards. Focus beam is square and covers about 10ft at about 100yrds. Not bad for the price and does the job. The beam has a cross in the square and the center is shadowed out and that's the only thing I don't like about it but hey it's 20 bucks. No battery so you'll have to buy and if you unscrew the clip to put it in a mount the screw holes will let water into the battery compartment

I really like this lightweight, IR flashlight for use with my digital NVG set up. This mounts to a helmet very quickly and easily with a flashlight mount. As for the features and operability, the 940nm means that the light is functionally invisible to the naked eye unless you stare at it. It appears as a small burning dot, offering a definite advantage over 850nm IR light. The zoom function is also a great feature, allowing you to flood a room or peer out to 100 yards with it.
