I attempted to use this product for night time hunting so maybe I could film it with the GoPro. Needless to say, I was unaware the GoPro has built in IR filters that prevent IR lighting to be seen. However, I do have a digital camera that does have a nighttime setting that does see IR and was able to adjust how I recorded after the sun went down. Good range on tight beam, would like to see a larger flood option though for closer range.

Working well good price

Unlike one other reviewer here, I did receive a 940nm unit. This means there is negligible visible glow, and great brightness under NV. The power and focus adjust are fantastic to keep from blooming out my NV and get the correct FOV. A dim green light on the tailcap lets you know when the light is on, otherwise there would be no real way to distinguish if the button were accidentally pressed.

Full disclosure--I work at a haunt venue, where we use NVGs during parts of the presentation. When we first started out, we had a pair of NVGs that were perfect...low-end military-grade, great sensitivity that didn't really need additional illumination for most of what we did. They were so good, in fact, that one of our maintenance guys decided to help himself to one...

And they were off the market, at that point. I searched through dozens of websites to find two or three who said they still had them in stock, but when we actually ordered, it turned out they didn't...so we ended up getting something else off Amazon (because we KNEW that would get there in time...) A lot cheaper, but also nowhere near as nice, and required the illuminator to be switched on to see anything (at the time, I didn't know anything about the difference between 850 and 940nm IR). We could only use those goggles under VERY specific circumstances, because the illuminator was visible to anyone looking in the general direction. It was subtle, but it was there.

We got by with those for a couple of years, though...and I kept shopping around and learning more, discovering that not all IR illuminators work on the same wavelength. We got another pair of goggles, with a 940nm illuminator...but an incredibly narrow field of view (like, if I held my hand out with my palm facing forward, at full arm's length, my palm filled up about 80% of the field of view, so the poor guy wearing them, while he didn't have to worry about the audience seeing the illuminator, could scarcely see where he was going.) I also had to fabricate 'eye cups' because the LCD screen put out so much light that the guy wearing the goggles effectively had a flashlight on his face anytime the lights were out, and everyone could see where he was in the space. Even with the eye cups, he still had to wear a black hood to reduce light spill around the edges...so, they solved one problem but created a whole bunch of new ones...

And somewhere in the midst of all this, someone suggested just buying a 940nm flashlight and strapping it onto the 2nd pair of goggles. So, we tried it...

We did have to modify a few things. The LED in the flashlight DOES glow red, very subtly, but in a pitch-black room, it's easy to see. We taped across the lens of the flashlight, leaving a square about the size of the LED cell directly ahead of it. If he's looking straight at you with it on, you can see it...but if he turns his head even 5-10 degrees, it's gone. Provides PLENTY of illumination for the NVGs (if you've got a pair on, he looks like a mobile spotlight), but as long as he doesn't look directly at any of the patrons, nobody can see that he's there (so he just tweaked his traffic pattern a little bit).

So, we now have a $150 pair of NVGs with a $30 flaslight on them that works WAY better than the $450 pair of NVGs that we bought to replace the $150 pair. I'm happy. My coworker is absolutely THRILLED. And our producer has another option if and when he needs to buy more. Easily worth the $30, to me!

Used this for my NVG’s for helmet mounted illumination and it worked a get. Recommend getting rechargeable batteries though if you like to use often.
