[MENTION=13059]zacster[/MENTION], you're running a 20" front wheel, right? Might that make a difference? Is the hub designed for small wheels? If not, you're spinning it fast.
I just put a B&M headlight on one of my dynamo-hub-equipped bikes. Man, that thing looks bright, compared to the halogen bulb it replaces.
