that is a good looking light.

No cutoff, so not legal on public roads in many countries. Also only IP65.

Looking good - I like the wireless switch, and the durable mounting system.

It is a mountain bike light not for road ways.

am i right, is it really supposed to sustain 2000 lumens for 3 hours after initial stepdown from 3000lumens?

looks like real chance of overheating and\or unsoldering. even 1000 lumen is damn lot for such a compact head

BTW, is that NW or CW?

ah, specs say 180 minutes and pics mention 140 minutes in 2000lumens mode...

Yes, you are right. Wuben B1 is suitable for mountain cycling.
