I thought I'd better wander in here and get some help with a problem I'm having with blowing bulbs with my dynohub setup. Disclaimer: I have very little knowledge of electricity and if everyone starts getting too techincal I will look blank and ask to to repeat it, simplified for dummies.
I am running a Shimano DH 3N20 dynohub built into a 20" (ERTO 406) rim on a fixed gear commuting bike. The light is wired to a 2.4w halogen headlight designed for a different hub dynamo and a B&M taillight. The head light has a sensor and comes on automatically but doesn't have a switch. I am constantly blowing headlight bulbs due, I am sure, to the higher speed of the small wheel.
I am sick of replacing bulbs and am looking at buying a new LED headlight, such as the B&M Lumotec IQ Fly Plus. I will have to import whatever light I buy. I am not skilled enough to build my own headlight.
Will I fry the LED headlight as well or will it be safe to use with my setup? Can I run a higher wattage/voltage bulb in my extisting headlight?
I did have the same problem with my recumbent which is fitted with a Sturmey Archer XFDD dynohub, but I solved that by adding a secondary headlight to it.
