I'm on duty in the middle east where I EDC(and use daily!) an HAIII MiniMag with Lambda's (thank you Kevin!) Mini-Pro III topped with a TWOJ. Light head is locked down with an oversized o-ring, operation is via Kroll clickie.
This is my benchmark. I feed it NiMh's, yet twice I have had to feed it alkalines I bummed from my crew members. This is why I love 2AA lights, for the ease and flexibility of feeding the flashlight. The L2P is the right light, at the right time. Only a Lux1, yet the specs indicate acceptable output versus an impressively long runtime.
4sevens, I will pre-commit to a group buy of the L2P. If you should have Fenix' ear, please relay to them that a Luxeon 3 version would sell well! Call it the L3P and run the LED hard (output like the Mni-ProIII), and with half the runtime, it would still be excellent!
