Another light recommendation.

The Fenix BC30 V2.0 looks quite neat.
Has a wireless remote switch, could give you more options for fitting it on the bars. And 2 buttons on the switch, so can quickly set it to burst mode.
Nice video explaining how it works. https://www.youtube.com/watch?v=WHhcOEoC7Ec

Lots of discussion about the bluetooth switch, not a lot about the quality of the light beam produced.  Looking at the photos/video it looks like a night vision destroyer due to the bright spots on the road just in front of you.

Depends on what angle it is pointing in, and what power you are using. I have an old Fenix BC21R, that is bright enough on low/medium power for most riding. Just switch to high power for fast twisty downhills.
The BC30 looks like a similar sort of thing, but with some brighter options.
