How much electricity do Christmas lights use?

Fact Checked Fact Checked

In this Canstar Blue guide, we crunch the numbers to see how much all those twinkling Christmas lights will really cost you this festive season.

Christmas is a joyful time of coming together with friends and family, and what better way to get into the spirit than with Christmas lights? But once Santa has been and gone, and those dreaded post-Christmas bills start rolling in, we quickly come dashing back to reality.

There is a long held belief that Christmas lights are a major culprit of Christmas bill shock, but we’re here to tell you that’s not quite the case these days. So how much are those Christmas lights really adding to your electricity bill? We’ve wrapped up the numbers below.

How much do Christmas lights cost to run?

LED Christmas lights will only add $1 to $5 to your electricity bill over the Christmas season. Nearly all modern day Christmas lights are LEDs, which have become popular due to their minimal electricity usage. After comparing dozens of lights, we found the average set of Christmas lights will consume 1.2W to 2W of electricity for every 100 LED light bulbs.

The below table compares the running cost of LED Christmas lights. For the purposes of this illustration, we are assuming an electricity usage rate of 31.88c per kilowatt hour (kWh). Depending on your distributor, provider and plan type, your usage rate will typically fall between 25c/kWh and 45c/kWh on the upper end.

LED Christmas lights running cost

Number of lights Wattage Hourly cost 24 hour cost Seasonal cost*
250 3.6W 0.10c 3.00c $0.77
500 6W 0.20c 5.00c $1.29
1200 12W 0.40c 9.00c $2.57
2000 20W 0.60c 15.00c $4.28

*Assumes lights used 24 hours a day for the whole month of December (4 weeks)

Bear in mind that while many LEDs only consume 1.2W per 100 bulbs, some may use nearly twice as much electricity, particularly those which flash or twinkle. Fortunately, even the most power consuming LEDs out there will only cost you a few dollars at most this Christmas.

Christmas lights can last many years when cared for, but if you’re still parading the incandescent fairy lights you bought 10 years ago, it’s probably in your best financial interests to move with the times and make the switch to LED Christmas lights. The savings on electricity will pay for the lights itself.

How you can reduce your power bill this Christmas

  • Consider solar Christmas lights: Solar Christmas lights are becoming increasingly popular as they cost literally nothing to power. The main drawback is, of course, that they require sunlight, which will only power the Christmas lights for a few hours into the night. They may also be a little more expensive to purchase up front.
  • Use a timer: If you’re going to bed early, use a switch timer to ensure the lights are not left on overnight, or only showcased for a few hours (this may also avoid complaints from those grinchy neighbours!)
  • Plan your light display: As we mentioned, flashing or twinkling lights consume more electricity. Unless you’re really trying to impress, stick with solid Christmas lights. Some more obvious tips are to only turn your lights on when it is completely dark (around 7pm depending on location), only have your display lit through December, and don’t overdo it with the number of lights.
  • Switch energy plans: With three fridges on and a house covered in lights, the last thing you’ll want to be paying is high rates. Take some time to compare your power deal with others in market to avoid bill shock at the end of the festive season.
