Perhaps no color represents the holidays better than green. Trees, wreaths, wrapping paper and now, eco-minded homeowners are "going green" by exchanging their old incandescent holiday light strings for energy efficient LED strings. The fourth annual Christmas Light Trade-In Program from The Home Depot provides the opportunity to recycle incandescent lights and receive a discount of up to $5 off of ENERGY STAR qualified LED lights, which use 65 percent less energy. When an estimated 100 million decorative lights will be sold in the U.S. this year, that energy savings adds up quickly. In addition to saving money, LED lights are better for the environment, with fewer greenhouse gas emissions. So make Santa proud and visit your local The Home Depot store between Nov. 1 and Nov. 14, 2012, to recycle old incandescent lights and feel extra festive when you decorate with your new eco-friendly LED light strings this holiday.
