How much would it cost to run Griswolds' Christmas lights from "National Lampoon's Christmas Vacation?"

How much would it cost to run Griswolds' Christmas lights from "National Lampoon's Christmas Vacation?"

Have you seen "National Lampoon's Christmas Vacation"? In the movie, Clark Griswold is determined to decorate his home with 25,000 Christmas lights It's a part of his plan to have a "fun, old-fashioned family Christmas." Watch the comical scene from this 1989 classic below.

But how much would it cost you to power your own massive light display for the entire month of December? Well, that all depends on where you live and what type of light bulbs you're using. Here's a map that shows how much cheaper it is to run LEDs vs. incandescent bulbs.

Based their numbers on the U.S. Energy Information Administration. Here's the formula they used to calculate the prices:

25,000 bulbs * 0.08 watts/bulb = 2,000 watts.
2,000 watts * (1 kilowatt / 1,000 watt) = 2 kilowatts
2 kilowatts * 5 hours per day = 10 kwh per day
10kwh * 31 days = 310 kwh
310kwh * each state’s average price per kwh

This is an amazing price difference....are LEDs a game changer? And will our future electricity bills be pennies on the dollar?

Maybe if you can afford to replace all your incandescent bulbs with LED bulbs. One person in the comments section pointed out that LED lights cost significantly more than incandescent lights. A pack of 100 incandescent lights regularly cost about $3 on the Target website, so buying 25,000 lights would cost you about $750 before tax. A pack of 100 C9 LED regularly cost about $25 on the same site,  so 25,000 lights would be a whopping $6,250 before tax.

Presumably, the cost of the lights is a one-time expense. So if you're not planning to use 25,000 lights, it could end up being cost effective in the long run.
