The Energy Guy

Saving Money on Holiday Lights

By Reuven Walder

Can LED holiday lights save you money?  To answer this question, I compared the power used by a strand of regular incandescent Christmas lights with LED Christmas lights using a Kill-A-Watt meter.  The Kill-A-Watt meter is a tool used to calculate the power used by any plug-in electronic device.  You can use a Kill-a-Watt meter to calculate the cost to run that device over the length of a day, week, or month.

My testing revealed that LEDs use 80 percent less power than your standard incandescent bulb and offer even greater savings when compared to a strand of large incandescent bulbs.  Although a strand of LED bulbs can cost up to four times as much as a strand of standard incandescent bulbs, they last much longer than their incandescent counterparts and they don’t break easily!  This can add up to significant savings over several years or even for a single season if you use a large number of lights.

The reduced energy cost of LED Christmas lights and the durability of the lights, more than make up for the LED’s premium price over several years of use.  If you add a timer to your light array, you can even save more!

Kill-A-Watt meters are a great tool to help you to reduce electricity consumption from appliances and devices plugged into your outlets.  Stay posted for a future article on ways to use this handy tool in your home.
