Does not work. save your money - INFORCE Multifunction LED Weapon Mounted Light

I have several of the first Inforce lights to come out, decided to upgrade to a high power light so I can see farther in open area tactical situations. This light works when it feels like it, which is hardly ever. I would definately not trust my life with it, I tried to return it, but could not get the return labels to print. I'm Military and don't have time to mess around trying to return equipment that don't work, or return labels I can't even print, I guess its just another piece of junk in the spare parts box, all in all save your money for a light that works.
