DID YOU KNOW? LED (Light Emitting Diode) holiday lights use up to 95% less energy than larger, traditional holiday bulbs and last up to 100,000 hours when used indoors. LED holiday lights use .04 watts per bulb, 10 times less than mini bulbs and 100 times less than traditional holiday bulbs. Over a 30-day period, lighting 500 traditional holiday lights will cost you about $18.00 while the same number of LED lights costs only $0.19. As an added bonus, if one of the LED lights burns out the rest of the strand will stay lit.
