I now have H4 conversion headlight housings in my car, so I'm back to looking at HID kits. They come in 35W and 55W, are the 35W kits really weak? I'd rather run that one because I'm concerned about whether the 55W bulbs might get hot enough to damage the housing (just an eBay special after all) but if the 35Ws are not significantly brighter than stock halogens than I'll try the 55W.
