Really interesting discussion here, probably one of the biggest current debates on here that I've seen (the issue, not this thread)... can't say that I've been around S&A much though. I'd have to think this over some more before contributing any of my two cents, or maybe I'll start a "do brighter lights make you safer?" thread in it's proper forum if there isn't already one.
While this is going on if any of you wouldn't mind posting some links to the Cree, Bull, or other lights it would be appreciated.
