The holiday season is upon us. And with that comes gingerbread, sugar plum fairies, and twinkling lights. But this year think about making your twinkling lights sparkle with LED efficiency. LED holiday lights use 90% less energy than traditional bulbs do. Oh, and they also last for 20 years! So instead of paying $175 on lighting incandescent bulbs (based on burning 10 strands with 100 lights each for eight hours a day for a month), spend $1 for lighting the LED equivalent.
