I'm building a winter bike with an Alfine internal gear rear and dyno front. My first foray into dynos. I've always been a battery light guy up until now and prefer LMI stuff and currently own four of them. I'm kind of jacked about the possibilites of self-powered light, though. I've been to Peter White's site and others, and am pretty overwhelmed by the options. Unfortunately, I don't have much internet or tinker time right now, so I'm turning to you guys to point me in the direction of something that will work well out of the box. Is there kind of a gold standard in dyno lights? I'd like to keep it under $100, but would go to $200 if that's what it takes to get a reliable light that performs well. I'm looking for reasonable quality, because I can't stand junk. The Alfine is standard 6V/3W. Thanks in advance for your time and help.

I guess the gold standard of dyno lights was the Schmidt E-6. That lamp alone cost about 100 USD. A lesser expensive option is the Bisy. It has the same reflector and lense that gives the E6 it's popular trapazoid beam pattern. The Bisy is less expensive because it uses plastic instead of a metal housing. Additionally the E6 had a tool-free bulb change while the Bisy had a single screw that had to be loosened. Truth was the bayoneted construction of the Bisy was tight enough that you could pitch the screw.

Now there are some nice LED lights that can be Dyno driven. A web site you should check out is by Pamela Blalock. She is a veteran of many 1200K randos like Paris-Brest-Paris and Boston-Montreal-Boston and is a big proponent of dyno lights. Her website has a good history of her past systems and present set up and is good reading.

Thanks for the reply - it helped a lot. I ended up ordering a Lumotec Fly. Not sure about anything, but think this will be a good, inexpensive place to start.
