just dunked my SureFire G2 incandescent in a pan of water..will give it a couple hour soak...polymer body... "O" rings... switch is a simple twist or momentary on button, with not a bunch of modes....since the start of this thread I ordered a small one cell 123 powered LED pocket lite to augment my Fenix on the key ring...thinking about getting one of the G2XB lights, SureFire supports my shooting habit


Edit...it's at least water resistant after 2 hours...
