Full-service Christmas light installation, starting at $500
Some Christmas lights run on 12 volts, but most don’t. Traditional incandescent lights are made for 120-volt household power and need a power inverter to work from a 12-volt battery. Many LED lights come in 12-volt versions that plug straight into batteries and off-grid setups.
Incandescent Christmas lights usually last about 1,000 to 2,000 hours of use, or a few holiday seasons with normal use. How long yours last depends on how many hours a day they’re on, the weather they face, and bulb quality. Regular checks and careful storage help them last longer.
Yes, you can use C9 LED bulbs in most old C9 light strings, as long as the sockets are the standard E17 size. Before switching, check older strings for frayed wires, corrosion or worn insulation, since damaged wiring can cause flickering or become a safety hazard.
Christmas lights come in many types, each with its own best use. C6 bulbs suit garlands, wreaths and trees, C7s outline roofs and paths, and bright C9s light up large areas. Mini LEDs, G12 globes, string lights and icicle lights each add their own look to your display.
Christmas lights are big business. About 150 million light sets are sold in the U.S. each year, and switching from incandescent to LED lights can cut the energy they use dramatically. This infographic rounds up surprising stats about Christmas lights, spending, energy use and trends.
