Go ahead and buy it and turn off your main breaker in the home and use it as a candle and see what happens.
But Bostonbob only has a few posts...do we want to see him killed off this soon?
I'm happy to see you guys have my best interests in mind! 2000 lumens in hand is screaming, "do it!"
I'm lusting after this tiny monster in a big way, and I need to justify my purchase of a battery charger to "the boss."
Personally I'd rather talk you into a JetBeam RRT-3. It's not all flood and can throw pretty well. It's got more mass so it can handle the heat better. It's got more available light levels. And, I think the RRT-3 has a smarter battery setup than the TM11.
