Energy-saving LED light bulbs fuel this insane light display
Okay, it's no Dancing Dror, but this is a pretty amazing Halloween light display done primarily with LED bulbs. Switching to LEDs can cut your holiday lighting energy expenditure by 90 percent, according to DOE (though they're just talking about a Christmas tree, not a full-front singing house display), and widespread use of LEDs for everyday illumination could reduce electricity use for lighting by 33 percent. A display like this is still kind of a giant energy hog, but so much less than it would be with incandescents!
