I'm overwhelmed with choices. Currently I use a Surefire E2D as EDC light and had gicen some thought to buying a ring mount and using it on my AR but I think I can do better. My specifications: I'm not interested in cobbeling something up and I'd prefer it to run on CR123 batteries and have a push on-push off tailcap. No strobe/s-o-s/high beam/low beam. Just "ON" and "OFF" please. The more lumens the better for two hunnred bucks or less. (less is always better; I'm "thrifty") So, what are my choices ?
