Review: Excellent adjustable alternative to IR illuminators. - I wanted something that I could adjust for my night vision scope. The infrared illuminator that came with it was just way too bright for anything close. I have my night scope mounted on my crossbow. Being able to turn it down is really nice for stuff close (under 40 yards).
Review: Best light available for NV, but hard to mount - I'm very impressed with this light. The tailcap has adjustable power and is easy to click. The head is easy to zoom. The beam is very useable, clean and even without hotspots. Can be adjusted very wide for a flood effect or narrow enough to reach 300 yards or more. It's so much better than the 940nM light I had previously. I don't think there's anything else on the market that compares. The body diameter is 28mm, making it hard to find a mount. The best one I found for it is the 'UTG Angled Offset Low Profile Ring Mount' which is 27mm and worked fine.

### ⭐⭐⭐⭐⭐ Excellent adjustable alternative to IR illuminators.
*by J***S on March 1, 2025*

I wanted something that I could adjust for my night vision scope. The infrared illuminator that came with it was just way too bright for anything close. I have my night scope mounted on my crossbow. Being able to turn it down is really nice for stuff close (under 40 yards).

### ⭐⭐⭐⭐⭐ Best light available for NV, but hard to mount
*by A***S on September 26, 2024*

I'm very impressed with this light. The tailcap has adjustable power and is easy to click. The head is easy to zoom. The beam is very useable, clean and even without hotspots. Can be adjusted very wide for a flood effect or narrow enough to reach 300 yards or more. It's so much better than the 940nM light I had previously. I don't think there's anything else on the market that compares. The body diameter is 28mm, making it hard to find a mount. The best one I found for it is the 'UTG Angled Offset Low Profile Ring Mount' which is 27mm and worked fine.

### ⭐⭐⭐⭐ Feels solid and is very bright, dimmer function leaves much to be desired.
*by G***O on May 9, 2025*

So far fairly solid. The good and the bad. The good is that it feels quality and like it will last assuming you dont drop it on the road, weight is kind of heavy which gives it the quality feel, and it is definitely bright. The bad is that although it has a dimmer function it really doesn't change the light intensity that much which is dissapointing, and the flashlight is bulky around the middle so you cant really attach this to a helmet or something with available mounts. It comes with a battery (3.7V standard mini flashlight battery), a battery charger, as well as a AAA battery adapter to use instead of the 3.7V big fat battery. I have tried it out with an NVG30 digital night vision monocular and the light is great for illuminating for night vision.
