Well there`s LEDCorp`s "Pro Series" LED replacement bulb, but I don`t know of any other complete lights- not yet. Luxeons are relatively new and there`s probably a wad of other manufacturers working on designs using them- who knows what the next year will bring? Arc LLC are the first to release a LS light, but I expect it won`t be long before others jump on the bandwagon. Watch out Nichia, that`s all I can say!
