Light your holidays with LEDs

The winter holiday season has officially begun, and with it comes the frenzy of decorating, holiday gatherings and gift buying. Don’t let your energy-saving efforts fall by the wayside amid all the festivities.

This holiday, light up your home with LED lights. In addition to being sturdier and more resistant to breakage, LED holiday lights also last longer and consume 70 percent less energy than conventional incandescent light strands. It only costs 27 cents to light a 6-foot tree for 12 hours a day for 40 days with LEDs, compared to $10 for incandescent lights.

LED – or light-emitting diode – holiday lights are much more efficient than traditional incandescent lights. While the initial purchase price of LED light strings is higher, consider the cost of running each type of light string for 12 hours per day for 40 days:
