I was researching some of this stuff a while ago (LED conversions of vintage lights for use with vintage DynoHubs, that is), because I also have a 1930s-40s 8-volt DynoHub that I want to use with a bike of the same age. What I learned then is that most LED bulbs don't tend to work very well with parabolic reflectors. I did find some that were sort of a "tree" or cube of LEDs, though, so that they would at least theoretically work better with that type of reflector....but then there's the question of getting it to work with the 8-volt hub.
