Fact: For a small display, that might be true, but larger or more traditional Halloween displays can soon add up, especially when they’re running for hours every evening.
The biggest difference comes down to what you’re using and how long you leave it on.
🎃 LED lights use around 80–90% less energy than traditional incandescent lighting, making them a much more efficient choice. Older incandescent lights use considerably more electricity. According to NRG, older-style string lights can cost up to £3 to run across October when used every evening.
👻 Going all out? Multiple strings of lights, projectors and plug-in inflatables can increase energy use much more noticeably when they’re left running for hours at a time.
Want to keep the spooky display without giving your energy bill a fright?
Choose LED or solar-powered decorations where possible
Use timers so displays switch off automatically
Turn plug-in decorations off at the wall when they’re not being used
