Peter White cycles carries generator hubs and generator lights. Lots of info on the web site too regarding lights and generators they offer. Ordering can only be done by phone or letter as they are not equipped to do internet sales.

As to output levels, the current brightest commercially available generator light seems to be the Busch & Muller Lumotec IQ Cyo at about 80 lumens. The 600 lumens mentioned earlier is for home assembled multi LED generator headlights. Here is a link to plans.

The higher power lights put out considerably less light except at higher speeds with either hub or bottle generators from what I have read.
