Permanent Lights and Your Electricity Bill: The Real Numbers
One of the first questions people ask about permanent lights is whether they will run up the power bill, especially if the plan is to use them most nights of the year. It is a fair concern, and the honest answer is reassuring: modern LED permanent lighting costs very little to run, far less than most people expect.
Why LEDs cost so little to run
Permanent lighting systems use LED points, which are extremely energy-efficient, drawing a small fraction of the power of the old incandescent bulbs people picture when they think of holiday lights. A whole roofline of LEDs draws modest power, and running it for an evening costs on the order of pennies rather than dollars.
The exact figure depends on the size of your system, how many hours you run it, and how bright and colourful a scene you choose, but the scale is small. Everyday use of a restrained warm-white scene is cheaper to run than many people's assumptions about a single string of old bulbs.
Everyday use is realistic
Because the running cost is so low, using the lights as everyday architectural lighting, not just for holidays, is entirely practical. A soft warm-white wash on the rooflines most evenings adds curb appeal year-round for a trivial amount of power, which is part of what makes a permanent system worth the install.
Brighter, full-colour festival scenes draw a bit more than a dim warm white, but even then the cost is minor for the occasions you would use them.
The bigger cost picture
The running cost is genuinely a footnote in the overall value of permanent lights. The real economics are in the upfront install versus the recurring cost and hassle of traditional lights, hiring installers, replacing failed strings, and the annual ladder work, which is where permanent systems tend to pay off over time.
So if the power bill is what is holding you back, it should not be. A free design consult gives you the exact system size for your home, from which the running cost is easy to estimate, and it is reliably small.
