Splat,
I would love to have seen a video of the flame and smoke trailing behind you as the helmet light melted down!

Seriously, though, folks, did you assemble your own LEDs on that light? I just put a 48 LED MR16 replacement in one of my headlights. I will be trying it for the first time tomorrow and will post a report. It seems pretty bright but obviously weak compared side by side with the 35W I usually use. I am figuring it to be about like a 10W. I don't know if I can be happy with that for regular commuting, but it might be adequate where battery life is at a premium. I need to hook it up to a meter to see what it draws. Will report on that too for anyone interested.
