I have noticed that 4Sevens has XM-L lights (Maelstrom X7) which they rate at about 480 Lumens while I am seeing other vendors on-line listing XM-L lights at 1000 lumens. I am curious about the large delta in lumens.
Is the delta because they:
*aren't the same type of XM-L LED?
*are the same LED but being driven differently?
*are the same led but venders are overstating the lumens or counting lumens at the emitter vs Out The Front?
Finally, assuming these are the same LEDs and the brightness is the same, I am curious if people feel the chinese lights found on DealExtreme that are about 1/3 the price of the 4Sevens model are a case of "you get what you pay for".
