Why Calculate Your Christmas Light Cost?

It’s a holiday tradition to deck the halls, but for many families, the January electric bill is a nasty surprise. Older incandescent bulbs (especially the large C9 ones) are notoriously inefficient.

🚫 Incandescent C9

Uses ~7 watts per bulb. A typical roofline can cost over $100 to run per season.

✅ LED C9

Uses ~0.06 watts per bulb. The same roofline costs less than $2 to run.

By using our Christmas Light Cost Calculator, you can make informed decisions before you hang your lights. If you have old strings, check their wattage. Often, buying new LED lights pays for itself in just one season of electricity savings.
