how much electricity do xmas lights use

The electricity usage of Christmas lights can vary depending on the number and type of lights you have, as well as how long you keep them on. On average, a typical set of Christmas lights can use anywhere from 10 to 50 watts per hour. If you have a large display with multiple sets of lights, the electricity usage can add up quickly. It's important to keep in mind that Christmas lights are designed for temporary use, so it's best to limit the amount of time they're on and turn them off when you're not home to save energy.
