I read a neat article recently that talked about the "Dubai Lamp". They're lightbulbs that Philips makes for Dubai that are twice as efficient as their standard LED bulbs. The difference is simple: LEDs are more efficient when run at lower power, so by increasing the number of LED elements in the bulbs and reducing the voltage across them you get 600 lumens for 3 W. For reference, California requires lightbulbs to operate at 80 lumens per watt or higher.

Looks like they're bringing this idea to the rest of the world:
