I realize not many will have use for one of these but I'm wondering if there is ANYONE out there that has one or has seen one. I have thought about getting one for NV use, but since I don't know a lot about infrared, can anyone tell me....say, if you are in total darkness, is there any visible light emitted (without the use of night vision equipment)...? Is there any light coming out that you can see with the naked eye?
