If you've watched the Christmas classic "Christmas Vacation" maybe you've been left wondering this: How much money would it cost to run Clark Griswold's Christmas light display?

We can provide two different answers thanks to Estately Blog:

1) 25,000 LED lights- $57

2) 25,000 Incandescent lights- $4,986

These costs would reflect 5 hours a day, for 31 days. 

So how did they figure out the math? Here's a simple formula they used:

Here’s our formula:
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"

Lighting up the house is most expensive in Hawaii ($86 using LED, $7,552 using incandescent) and Alaska ($65 using LED, $5,656 using incandescent). The Griswold's would spend the least amount of money on this display in Louisiana ($30 using LED, $2,582 using incandescent) and Washington state ($30 using LED, $2,615 using incandescent).
