CPF had a big forum crash not too long ago, so it’s a bitch to read the thread, which has all been recovered from google cache. I’m not through reading it yet, but lots of interesting discussion/catfights. Techjunkie is only so trustworthy I peg him at the reliability level of an automotive hot-rod enthusiast. Unless he’s flat out lying though, he’s got a set of 3 mags that show a big diff in running XM-L at 3.4, 4.2 ,5.0 amps. the OP on the other hand has tested 3 samples that all seemed to like no more than 3.5A….
in other news, OP has posted some vF numbers that are straight fucking crazy:
1A – 3.000v
2A – 3.103v
3A – 3.147v
4A – 3.177v
5A – 3.218v
that is LOW… way lower than the datasheet suggests (~3.420vF @ 3A I think). Makes for flashlights that stay in regulation longer, etc etc.
techjunkie also says that he likes the XM-L better than the SST50 in every way basically… better lumen performance, better throw in same reflector, etc.
