Hey Guys and Gals, I would like to get a small keychain size torch. I prefer a AAA, under three inches, twisty or clickie, at least two modes (prefer three), starts at low and low has to be under 10 lumens (preferably under 5) and have at least a 50 hour runtime on low and 2ish hours on high. Also would like to be able to use lithium primaries. It will be a keychain light and also something to jog with at night if I have to wait that long. I already have a pair of Streamlight Scorpions, Surefire G2? tactical and a couple of multi-cell Maglights for other carry purposes. I've been looking at the Maratac, iTP/Olight and Klarus lights. What has worked good for you guys? Thanks.
