Ok, I want a light to keep on my keyring. A jet1 AA is not too big. I'd prefer the CR123 body, but at over $70, just can't justify it. So, i'd be running a RCR123 in the P1 or a 14500 in the Jet1. Supposedly the Jet1 is upper 70's lms with that battery and the P1 is ~50-60? with a RCR123. I can't decide. Price is near the same since I have to buy a charger and light anyway. Anyone have any useful suggestions? I'd be open to other light suggestions in a similar price category.......*throws several single shot pistols out onto the ground and runs* Let the duel, I mean debate begin!
