The new lights tend to be a bit more efficient than the old incandescent bulbs, so the prospects are good. Of course, the Dynohub is lower power than more conventional dynamos; 1.8W vs 3W, so it seems likely that the Dynohub systems might have used a less powerful taillight too.
How is the performance of the vintage headlight with the Dynohub? I've got a good bit of experience back in the 70's and 80's with marginal headlight designs combined with a 3 watt bottle dynamo. It was good enough for the time, but just horrible compared to anything modern. If it was me, I'd be looking for a way to sneak an LED into that headlight.

The current headlight is basically useless as far as being able to see with it, but it looks cool. I wouldn't be opposed to setting it up with an LED of some sort, if it can be made to work well with the parabolic reflector (which really needs to be re-silvered). Something I read earlier does make me wonder, however, if perhaps I have a bulb that's less than ideal for this hub in it.
