I have recently received my E01, and I hesitate to complain to much. The quality is excellent, and I knew it wouldn't be that bright. BUT, the CPF safe light seems much brighter, and it only uses a CS led vs the GS led of the E01. Why? Is the safe-light driven a lot harder? It claims 20 hours on high from a 9V, and the E01 10 hours from a AAA. Or is it some trick of the optics used on the safe-light? I would like to see a GS put in the safe-light, but the few threads I read about modding them didn't go very well. Apparently they aren't really designed for disassembly, huh?
