LED holiday lighting uses about 1/10th the electricity traditional incandescent lights do, and switching to LEDs can yield significant savings during the holiday season.
Traditional holiday lights are little incandescent bulbs in two major configurations: “Mini” Christmas lights – tiny little cylindrical bulbs that look like tiny fairy-sized glass candles. Each little bulb on a mini strand uses 0.43W of electricity.
The larger lights are C7 and C9 bulbs. C7 bulbs are about an inch and a half long and consume 4-5W of energy per bulb. In addition to holiday light strands, C7 bulbs are also used in night lights and electric window candles.
C9 bulbs have the same profile, just a little wider and between 2-2.5 inches long. Because of their increased size, C9 is a much more popular size for holiday lights as the lights stand out better at a distance. But, C9s consume 7W or 10W per bulb, depending on the design.
Many LED Christmas lights come in the same configuration as traditional lights, just with the incandescent filament swapped out for an LED bulb.
In general, LED lights consume 1/10th of the power of their incandescent counterparts. LED mini holiday lights will consume about 0.05W per bulb, while C7 and C9 bulbs consume about 0.2W per bulb.
There is little difference between the two sizes when dealing with LEDs than the shape of the bulb—the LED component is typically identical.
“The cheapest energy is that which we don’t consume”. With LEDs, we can all consume up to 90% less, saving ourselves money while having a positive environmental impact.
It doesn’t get much better than that!
