I'm looking for a flashlight for field work and general use. I've been a fan of surefire lights, I've used them all over the world and haven't had an issue. That of course was with Uncle Sam giving me me boxes cr123 batteries to chew through, and I'm not that lucky anymore. I'm not trying to complain about the price or availability of cr123 batteries, BUT .. I am running into the issue of running out of these batteries and having to pack them out as trash (after being depleted) on extended backpacking and field work. I would like to get a flashlight that has rechargeable batterie(s)... I'm pretty much only looking at AA and 18650 powered lights. AA because my headlamps all use eneloop AA's, and 18650 because it seems that they are a great power package and there are a few quality chargers for them that are affordable. I really don't like having to click through a number of settings; I really want a click on/off tail-cap. If I have the ability to 'lock-in' a setting and use the tail-cap as a on/off switch, I'm happy. I would really prefer a simple on/off. Not looking for a search light, something in the 200-400-ish lumen output is good for me. So in a nutshell: 1. I'm looking for a surefire (like) flashlight simplicity. 2. Runs on AA's or a 18650 cells. 3. Physical size of the light is a non-issue. 4. Number if cells needed to run the light is a non-issue. 5. Minimum output of 200 lumen. Thanks!
