Once again, well-done reviews. I'm quite happy with my modded HDS but that T5 looks AWESOME for a single cell light!
But man, that K2 module looks kinda sad. I realize that there is a world of differences between converter boards, but I'm at a loss as to how the 2xAA Minimag can have 50% more outut AND 50% longer runtimes. I mean, assuming the Mag converter is 80% effecient (which I would venture is already an optomistic estimate) then does that mean the K2 is only about 50% effecient?
That's just sad.
Is this because of heat issues maybe? I don't tend to think so because even then, the very initial brightness should be above that of the MagLED.
