Very first - KL1. I already had an E1e prior to discovering CPF, after looking at Surefire's site just one time too many.
This was when folks were still griping about receiving LDs in their KL1s, and the purple/green tints. I was comparatively lucky, I received one that I suspect is a "V1" tint, very yellow though. But it is indeed a high dome.
Latest lights would probably be the SRTH Turbohead, A2 Aviator, and various Pelican bulbs to mod Mags with.
