I saw these at Home Depot and bought a couple on a whim. Then I realized it might make a viable indoor SD weapon light. The little thing lights up the room enough to identify the target and illuminates the bead on my 870 barrel at the same time. The weapon light on my AR will peel the paint indoors by comparison. I don't know how long it will last but I test it weekly and it's still bright a year later.
