You can get lower wattage H1 or H3 bulbs, it's just a royal pain in the ass to special order them. I've seen them as low as 20 watts when I was still in the bike business full time, as a stocked item. Anything less (down to 3w) was special order only, with obligatory $25 fee on top of the part price.
I was going to pull one and take it to "Batteries Plus", they just added lighting and say they have bulbs for everything. I got these at O'Reilly's. They're about 2 inches across. They had some bigger ones that might have been more wattage. We also have some pretty decent custom lighting stores that carry a LOT of custom bulbs for art lighting, pin lights etc. etc. I've had good luck finding odd ball halogens there.
