grows sick of the Soubitez. Best price I see is 96 euros a pair from CNC
Hamburg on ebay, no overseas shipping available, though.

DRL does not require more than 100 lumens if you get the optics right.

It's a bit puzzling how folks seem to excuse poor design in dynamo hubs
when they're considerably more fanatic about optimizing every other part
of a bicycle.

There's little competition in dynamo hubs and an extremely limited
market for higher efficiency hubs that would require different lights.

If someone could build a 6W hub that could be rectified and power and
charge a decent commute light then it'd be great, but most riders that
need that much light for commuting have already moved on.
