For Rob who might experience mental drag uphill from just having to
see a
big, heavy, non-laminated hub slowly revolving in the front wheel, the
smallish Shimano DH-T780-1N, 1.5W 250mA class, might suffice[1] once he
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.

True, but if you want a dynamo light for more than just a DRL then that
won't do.

I have an SP dynamo (relabeled as "Joule") on a 20" wheel on a Dahon.
It's coupled to a European dynamo light with about the best optics
available, but at a claimed 200 lumens it's still really only useful as
a DRL, plus it does not have a flash function.

What light is that?

I've had one person (hard to find many people with dynamo lights at all
in the U.S.) with the super-expensive Supernova light wonder ask me
about it since they wonder why their lights aren't illuminating as well
despite the higher lumen rating. It's all in the optics. The Herrman's
optics are especially well designed. Even at $100 it's not a cheap light
though. And there's no flash function. And you have to order it from
Europe of course.
