Anyone experimented with an LED bike headlight ?
I homebrew a 20 LED array that I powered from a standard (talking of Europe) 6V / 3W dynamo.
It performed nice, LEDs give light at very low speeds and need no zener to limit the dynamo output voltage. A dynamo is naturally a current source, so no control circuit for the LEDs is needed.
However, I found it inadequate for speeds above 15km/h as it doesn't reach into the distance like my Union Halogen Parabol.
