I don't own one (yet), but something has been bugging me about this light. According to the runtime graph at flashlightreviews.com, there is about ~4 hours of regulation (rounding up). Assuming we're pulling a reasonable amount of power from alkalines I expect to get ~ 2Ah of power out of each in a straight run. 4 batteries at 2 Ah each is 8 Ah of power used in less than 4 hours.. This puts power consumption at over 2 watts. Now, a low Vf Luxeon III, lets say 3.3 v @ 700 ma is just over 2 watts of power where a Luxeon I 3.3 v @ 350 ma is just over 1 watt. So either the circuit is 50% efficient or this LED seems to be way over driven, closer to Luxeon III stock currents. Given the good regulation, I don't think this light has efficiency that poor. I believe my math is correct...
Those who own them.. Has anyone taken the lamp assembly apart? Does the light use a luxeon star (replaceable?) or just an emitter? Would it be hard to swap in a Lux III star of one's choosing?
Edit: To specify 4AA ProPolymer.
