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.
There certainly are times when I've felt a need for more light, particularly when riding 20+mph on pitch black roads. That said, the ~400-500 lumens is plenty bright enough to avoid a *stationary* obstacle in front of me. Any video of lighting is more indicative of camera low-light sensitivity than of actual brightness.
I'd invest in more lighting, but I rarely ride at night so it's hard to justify the expense.
