Folks this IR works best with Gen 2,3 and digital NV not gen 1.It has a low to no glow 940 beam which means when you look at the front lens you see no to very very little red glow when its turn on compared to 805 or 850 IR Illum's which glow red at the lens base making them visable in use when you look at them in the dark. The 940 IR is designed for "stealth" and range suffers alot from the 950 beam if you need a IR for gen 1 or long range buy the 805 model. This Ir works great for what it is designed to do shorter range "Stealth" no glow use. I find with my gen 3 NV I get about 100 yards of good IR range.
Pros: Can't been seen by human eye
Cons: Less IR range
