I own both the lux and Cree fenix P1 (my cree is the Q2 SE) and find them both to be almost the exact same size. The P1D's are longer, so I prefer to carry the non-D models as an edc. I think both these single mode lights are small enough for very easy EDC. Also, my P1 SE Q2 with a 3.7 volt rcr123 is much brighter than my Nova-Tac120p with the same battery- an unbelievable sight coming out of a light about half the overall mass. (But this is a short run set-up only.) Even on a regular 123 primary, the light is plenty bright, with beautiful hot spot / throw combination. Don't overlook this light. As posted earlier, they are still available.
