Yep, Gerber got a winner when they bought CMG Equipment and got the Infinity Ultra with it. It was my first regulated LED light and I have a few. Simple, and so far all are still working as designed. Using one of these as a battery case is not a bad idea, although I believe the delrin case is a tad more waterproof than an Infinity with the cap screwed out to ensure no battery drain; dunno, the Infinity is fairly tight, supposedly waterproof to a depth of 10 feet.
