Guilt-free Christmas lights

December 26, 2008

Bah humbug – these days, it seems even Christmas lights can’t escape scrutiny. How green are your outdoor lights?

If they’re the old-style lights with the big 7 cm long bulbs, yikes: a string of 25 takes 175 watts of power – equal to 13 compact fluorescent light bulbs.

But if they are the new outdoor LED lights, phew: a string of 75 lights uses 3 watts or less. That’s right – three times as many bulbs, a fraction of the power.

In dollars, that means using 75 LED lights 5 hours a night for 30 nights costs just 4.5 cents, compared to $7.95 for 75 old-style big bulbs. And many of us put up a lot more than 75 lights.

Make LEDs a part of your green Christmas. They use 99% less energy than old-style outdoor lights, so you can light up the neighborhood guilt-free for pennies!
