Do Christmas Lights Use a Lot of Electricity? Here’s the Truth
Many homeowners ask, “Do Christmas lights use a lot of electricity?” The truth is simple. Modern LED lights use far less energy than people expect. When you understand how electricity use works during the holiday season, you can decorate with confidence and enjoy your display without worrying about your bill.
Below, we break down how much energy Christmas lights really use and how to keep your costs low.

Do Christmas Lights Use a Lot of Electricity Compared to Old Styles?
Traditional incandescent bulbs used a surprising amount of power. They created heat, burned out fast, and required more electricity to stay bright. LED Christmas lights changed everything. They use about 80–90% less energy. This means you get a brighter, safer, longer-lasting display for a fraction of the cost.
Do Christmas Lights Use a Lot of Electricity With LED Bulbs?
LED bulbs use very little power. A single C9 incandescent bulb uses roughly 7 watts. A C9 LED uses about 0.8 watts. This major difference adds up fast. Because LEDs stay cool and use advanced technology, they deliver strong brightness with minimal energy use.
Most homeowners pay only a few dollars extra per month to run LED holiday lights.
Electricity Costs for Christmas Lights Explained
Electricity use depends on four simple things:
The type of bulb you use
How many lights are on your home
How many hours per day they run
Your local electricity rate
When you multiply those factors, you get your seasonal cost. With LED lights, that number usually stays low. Many households discover that their holiday lighting adds the same cost as running a coffee maker for a few minutes each day.
Do Christmas Lights Use a Lot of Electricity When Installed Professionally?
Professional companies almost always use LED products. These lights last longer, resist weather, and use far less energy. Because of this, your electricity cost stays low even with a large, beautiful display. The quality of LED lights used by pros is higher than store-bought strands, which also helps reduce waste and energy use.
Tips to Reduce Electricity Use for Christmas Lights
You can save even more energy with simple habits:
Use a timer
A timer ensures your lights turn on and off at the right time each night.
Try a smart plug
Smart plugs let you set schedules and track energy use from an app.
Replace old bulbs
Retire older incandescent strands and switch fully to LEDs.
Check outdoor connections
Secure plugs and protect wires to prevent power loss and improve efficiency.
Each step helps keep your lighting cost low through the season.
