LED holiday lights are sweeping the nation. There's a good reason why they are showing up on Christmas trees and houses faster than you can say light-emitting diode. They pay for themselves.
A typical string of lights may cost around 30 percent more at the store, but take them home and plug them in. Your power bill for the LED lights will be up to 98 percent less. Not only will they immediately save electricity, LEDs are unbreakable and can last up to 20 years.
