I'd like to hear more about this. I'm running a cheap-azz flashlight mounted with interlocking hose clamps. I really like how bright it is (CREE XML T6, allegedly 1600 lumens, actually I don't know, but it's like a car headlight), I'm content with recharging 18650s (weekly, and I have a backup pair in the seatbag that will get me home if they fail early). I'm interested in maybe someday upgrading to dynohub, but are there super-bright CREE dynolights out there? Or starting to reach the market?
