The Schmidt Original Nabendynamo (SON) can power two 6-volt lamps in series at speeds above about 12 mph, and Schmidt manufactures lamps designed to facilitate this. These lamps have optics based on the Bisy FL road lights. The efficiency of the SON is quoted by the manufacturers at 65% (so just over 5W of the rider's output is diverted to produce 3W of electrical power) but this applies at only 15 km/h (10 mph). At higher speeds the efficiency falls. Bicycle dynamos instead use permanent magnets to eliminate the need for a battery to excite the field and initiate electrical generation.

Versatel is also a good deal. It's a bit more expensive than 1&1, but worth the few extra Euros, if you want a package which is tailored to your specific needs. They allow you to mix and match their services for a "customized“, cost-effective package.
