Granted.

Certainly an interesting light. Where did you get it? What are its voltage tolerances?

Thanks; this is, no doubt, good advice! But remember the title of this thread. Personally, I'm not using a bottle generator, but want screw-in LED bulb for my wife's 1966 Raleigh RSW-16 with its dynohub and lamps built into the fenders. I'm willing to put a bridge rectifier into the circuit somewhere, there's plenty of room for it in the headlamp; but anything more radical would compromise the classic look of the bike.
As for the Busch & Muellers... well, I've had very bad luck with their stuff, and it ain't cheap. I've fried two DToplights / Standlights for no evident reason, and have no idea how to fix them, or even diagnose the problem. I fried a similar Spanninga light too (not so hard to diagnose: the LED melted off its leads, and was rattling around inside the unit!). And all that was
before I rebuilt my Nexus dynamo hub into a 16" wheel, which now puts out 12 to 15 volts at moderate speed (so I'm running 12 V 5W halogen with some success). If anyone knows of an LED headlight that'll handle that kind of voltage, let me know.
No need to recommend a Schmidt SON20, I know about 'em. It's just not what I want.
