If that is correct, then Toshiba make something suitable http://www.toshiba.com/lighting/products/led-lamps/mr16-gu53.jsp although not quiet bright enough, they seem to max out at 35w equivalence.

Getting back to the original post, there's a company called Cree which manufactures LED modules for precisely this application. They announced these modules over a year ago and now, they appear to be "available" as ALT Asteria V6 bulbs, in several different color temperatures and light spread angles. There's one German vendor who has it for EUR 45 or thereabouts. I can't find an American reseller, making me wonder just how much these things are actually on the market, ready for sale.
