If I go by the video you showed me, it seems weak. I'm truly sorry if that doesn't work for you; it is however my opinion.

It is also my opinion that most (including my own) lighting setups are inferior to where they could and should be.

I am working on a solution (based off 24-hour mountain biking setups) that offers me a little more lead time on the light without feeling like I may have to slow down to avoid unexpected traffic changes.
