The lights on our holiday trees are L.E.D. lights. They are good
for the environment because they use 90 percent less energy than
typical incandescent holiday lights!
Why are L.E.D. lights good for the environment?
Each bulb with L.E.D. technology uses only 0.04 watts and is up
to 90 percent more efficient than its incandescent counterpart.
So a household burning 10 strands of lights for eight hours a day
for a month at $0.0853 per kilowatt-hour would spend $127.67 for
large, incandescent bulbs, $7.20 for traditional mini-lights, and
just $0.72 for L.E.Ds. These newer bulbs are sturdy, last up to
100,000 hours, or 20 years, and barely warm up, eliminating fire

Additional tips regarding safety and sustainable
- To maximize holiday lighting savings, use
timers to limit light displays to no more than six evening hours
a day. Leaving lights on 24 hours a day will quadruple your energy
costs and create four times the pollution.
- Be safe - Untended
lights can cause fires, so always unplug your interior holiday
lights before going to bed or leaving the house.
