re: Light for my AR?

An illuminator is used in conjunction with a night vision scope, which is not the same as thermal/FLIR.

Here's a good summary from google:

quote:

---

Thermal cameras see heat, not light. ... Atmospheric conditions, like smoke, rain, or fog, reflect light, making night vision goggles and scopes even less effective. But thermal cameras see through these obscurants and clearly. Night vision goggles and scopes also need to have the right amount of light to work well.

But an illuminator will not cast visible light that you can see. You will need a night vision scope to see the light cast by the illuminator.

EDIT: Generally "illuminator" is associated with night vision but in that link you provided it actually casts visible light. They make it quite confusing not just calling it a flashlight.
