Magnet Rings
The efficiency of the Magnic Light technique is achieved by usage of extremely strong neodymium magnets. The neodymium magnets have an energy density of 52MGOe (magnetization N52).

The key is so-called eddy current technology (http://en.wikipedia.org/wiki/Eddy_current): Energy is drawn from the rotating bicycle wheels without any physical contact, and thus without friction. Instead, eddy currents created by strong magnets generate electricity to power the lights:
Magnic Light lenses integrate two lenses for two LEDs in one lens while we use still use two LEDs for performance reasons.
