It stands to reason that the one using the XR-E bulbs would be fairly bright, but real world always speaks louder that specs.
Probably not the XR-E's, as I bought it a year ago. I think mine has Luxeon LED's.
Still, there isn't enough metal to properly wick away the heat generated by the XR-E running full bore (700mA or 1000mA). Running at 350mA puts each of the LED's at ~100lm for cool white, so the 240lm rating is about spot on (making each LED running at about 1W). Not bad for three watts... but doing the math:
80 Lumens/Watt
6 Lumens/Dollar (assuming the bulb is $40 shipped... remember this is just for the bulb, to get a truely accurate figure you would have to factor in the cost of a battery and charger)
You would stand to have a much more efficient system from an overvolted halogen (both in lm/W and lm/$).
