Frequently Asked Questions (FAQs)

1. Do string lights use a lot of energy?

A string of 25 incandescent C9 bulbs — the big plump ones often used outdoors — uses 175 watts of electricity, which works out to a whopping $15.12 to run over a season (assuming 12-hour-a-day operation for 45 days).

2. Are string lights more energy efficient?

In contrast, lighting the same tree with LED minilights only costs $0.82, making LED string lights significantly more energy efficient.

3. What Christmas lights use the least electricity?

LED lights consume 80-90% less energy than incandescent bulbs, and last up to 100,000 hours, versus 3,000 hours for an incandescent. Combine this with the durable construction of LEDs, and savings extend beyond electricity. Repeat purchases in LED lights are reduced drastically, multiplying savings year after year.
