I'm going to have to agree on the saint minimus bright as hell or really dim, nearly indestructidim, great battery life and truly a life long investment asking as u don't loose it or borrow it. You'll need a red filter or something though for it if that's something your sold on.

Big plus for me is I carry surefire G2 led as well so I only have to worry about grabbing a few C123a batteries, if you buy them bulk online there a really good value considering runtime weight and that they're lithiums.
