The image aboves shows a Hi-Point 9MM Carbine with an ARC LSH-P mounted in the Hi-Point factory fixture. It utilizes an AA power pack and is loaded with two lithium double-A's.
While some may argue the merits of using such a low powered light for use as a tactical, weapons mounted light, it sure enough illuminates the general area well. I think the LSH-P can serve usefully in some home defense situations for identification of friend, foe or pet. It looks kind of cool on there anyways..... The LSH-5 may be even better for this type of duty.
