Frequently Asked Questions
How much do Christmas lights add to my electric bill?
A typical display of 10 incandescent light strings running 6 hours a day for 30 days adds roughly $10-$15 to your bill. Switching to LED reduces this to about $1-$2 for the same display.
Are LED Christmas lights worth the extra cost?
Yes. LED lights use about 80-90% less electricity than incandescent lights and last 10-25 times longer. The higher upfront cost is typically recouped within 1-2 holiday seasons.
