Nice, maybe worth getting one now, but should I wait for the KL4 or just get a newer KL1 with it? I still love my C2 though! I sure wish they would change the clip to an E2O clip.
It depends what you want Luxeon light for. KL1 is available now and the KL4 which is far brighter has not been released and SureFire haven't said a release date.
I'd get both though because with the difference in output, they are for different applications.
Maybe they can make an L1-like body for the KL4, with two 123's and with three brightness levels instead of two. Level 1 = Arc AAA level, level 2 = KL1 level, level 3 = full 5 watts.
