Enter how many light strings, their type, and hours run per night to see the cost for the whole holiday season.
A typical 100-count incandescent mini-light string uses about 40-50W, while the same length in LED uses roughly 5W — around an 85-90% reduction.
Swapping incandescent mini-lights for LED versions typically cuts holiday lighting cost by roughly 90%, similar to the savings from the general LED vs incandescent comparison — but with the added benefit that LED strings run much cooler, reducing fire risk on dry trees and greenery.
For a typical 10-string display run 6 hours a night for 40 nights, incandescent mini-lights often run $30-50 for the season, versus just a few dollars for the LED equivalent.
Usually somewhat more per string, but the energy savings across even a single season often make up the difference, and LED strings also tend to last many more seasons before needing replacement.
