SON = Schmidts Original Nabendynamomehr Licht

Products - Dynamos


Petite and Lightweight

SONdelux is the first hub dynamo with a generator specifically designed for modern LED lights (such as Edelux and B&M Cyo).

Other than halogen lamps, LEDs are highly effective even at low power, i.e. when run below the nominal power/ its rated capacity. This is the reason why dynamos no longer need to be build in a way for them to reach full power at the lowest possible speed. Therefore, SONdelux is smaller and lighter than a hub dynamo for halogen lighting (SON 28).
No-load power input drops by about 30 - 35% compared to SON 28. But SONdelux equals SON 28 concerning durability and outstanding quality.

  Mechanical Power Input

With lights switched on SONdelux cuts down 1 Watt of driving power.
Nevertheless, at high speed Edelux reaches more than 80 lux. Even at 10 km/h Edelux gives more light than any other high quality halogen headlight at full speed.
