I stopped reading that post after I realized you were trying to say what batteries could be used with the other persons light...or whatever.

I see the link now and checked the site out. I have a question about their light mounts. I already bought a good flashlight recently and can't afford one of the fenix lights now. I assume that their lights are pretty much the same diameter as mine. I'm wondering if anyone has experience with using their mounts on different lights. Does anyone know if their mounts can be used on other lights?
