The $9.73 Extra to Make Your Tree Sparkle
You're (rightfully) proud of your cheerful-but-not-Griswoldian holiday lights, tangling and untangling the same strands for a dozen years. But the U.S. Department of Energy estimates that it costs $10 to light a six-foot tree for the season—if you're using incandescent lights.
Switch to LED bulbs, and you'll bring that cost down to just 27 cents
. That may not sound like much, but the same LED string could last you another 40 holiday seasons—that's $390—and your investment will pay off in other ways, too: The cooler LED bulbs are more resistant to breakage, less likely to lead to burned fingers and easier to install.
