Peter,
The need to reinvent the light is probably cost-driven or the desire to
be at the cutting edge of lighting design (ie being the first to use
these Cree lights when some of us are still trying to get the carbide
lamp lit).
Like you, my eyes glaze over when talk turns to wiggly-amps and things.
At least now I know I am not alone.
But, WRT the Lumotec, what is meant by a duplex wire? Does this just
mean two-core flex? If it is, I presume they do not want the bike frame
to be part of the circuit but to have the light and dynamo as a closed
circuit.
cheers,
Darryl
