Hi there everyone. I'm in the market for a single AA powered LED light for EDC. So far, I have surefire, fenix tactical style CR123 lights - but I want something smaller for everyday pocket carry and I like the idea of an AA battery. The lights I'm looking at ATM are Fenix LD12, LD15, E11, LED Lenser P5 and jetbeam BA10. Basically need a light that's as small and unobtrusive as possible. Really run time and output aren't that important (!) as it's simply a light to have with me at all times for general purpose use. I'd really prefer a light with a simple on/off switch, no adjustments and to be waterproof and shockproof. Thanks for your suggestions !
