In my quest for the perfect edc light, I think I'm finally realizing that I can't get just one light that will do it all. I'll probably get a few, and rotate them depending on need and what I want to carry. I'm thinking of Surefire L1, Olight T10, Wolf-Eyes Sniper, and Fenix L1D. Now my question: has anyone carrying a light that uses 123's ever been in a situation where you needed a battery, but couldn't get one because of the more unusual 123 format (as opposed to the more common AA)? This will help steer the direction I go in choosing my lights. Thanks everyone!
