At equivalent 55w power-consumption, you're looking at 5500-lumens, or more than 2x automotive high-beam lights.
Trick is mounting it into bulb-format. Most of those LED bulbs appear to use ceramic base, while heat-resistant, but doesn't actually conduct heat very well. I'm thinking of mounting to one-sided copper centre support attached to aluminium heatsink base (bottom is wasted in HID projector anyway). In which case, thermal-conductivity will be fast enough to not require those silly little fans they use.
