Very nice thread. Thanks for the comparison.
I really like Jetbeam but their naming convention still ticks me off.
I have a Jet-1 (MK) IBS, and this Jet 1 Pro business, versus Jet 1 Pro IBS, versus Jet II IBS, versus Jet III IBS, versus plain old Jet-1 MK II.r, etc is so dang mind boggling, it's like you have to get a PHD just to understand JetBeam's product line.
Threads like this are definitely necessary to try to figure out what's what. Jetbeam also does not explain very well the purposes of each light. A newbie would be lost trying to figure out if he/she should be buying a Jet-1, Jet-1 Pro, etc etc. Only detailed readings of selfbuilt's excellent reviews really reveal what each light is intended for / capable of.
Anyway I just wanted to say Jetbeam's flashlights are great, but the naming scheme is the worst in the world.
