About 2 yrs ago I bought 3 photon microlights - 1 EDC, 2 Gift. They all lasted about 6 months in a pocket with keys, change, etc. They just don't stand up to much abuse.

I currently EDC an ARC AAA-P (new version) with a lithium battery. Lite, bright and built like tank. <img src="/images/graemlins/grin.gif" alt="" />
