I have bought a couple of the battery version of the lights that dyno owners say are awesome lights. Supposedly exactly the same thing as far as light output goes. Let's just say I sent them both back within 24 hours. I would NOT care to ride my route with that level of light output.

It's all very well to have nice shaped beams and I wish we had more options available in the US for that. However, on my route I do NEED to be a certain amount obnoxious. On hilly/windy 2 lane roads with no shoulder and cars doing 60+ MPH, I want a light that will get attention instantly. I also want a boatload of lumens when I'm coming down the backside of a hill at 30+ MPH in pitch black.
