Thats an exciting development, but the article also mentions an intriguing sounding AC-LED designed for direct connection to an AC power source:
Seoul semiconductor developed a high power LED, Z-Power LED and an LED lamp used for lighting of households by connecting directly to AC power source. The company began was Z-Power LED to an automobile maker last year, and it plans to commercialize the Consumer LED lamp in the near future.
I havent seen a lot of reportage on this, but this looks very significant to me.
