I just purchased one of these mounts from an auction on eBay. It has an aluminum clamp with a carbon fiber dowel for mounting your light and it comes with some high quality aluminum shims. Despite it being listed as a "Computer Mount" it is very strong and supports my new generator light made by StevelKnievel (soon to be reviewed).

I looked at the Nitto and Topeak models, and I'm sure those work well, but this particular mount is exactly what I was looking for. I'm not a shill - didn't know anything about this mount before I bought it on eBay.
