Want to deck your home like Clark Griswold? Here's what it costs

You can decorate your outdoor halls more cheaply in Washington state or Louisiana than in Hawaii and Alaska.

Even Clark Griswold-ing costs more in Hawaii and Alaska.

Claaaaark! There's a wannabe Clark Griswold in every neighborhood, someone who maybe has more time than taste, and decorates their home as if electric lights are going out of style.

If that's you, or if you're wondering how much it would cost to make it you, consult this chart from, a national real estate search company that loves to research this kind of thing.

Researchers at Estately took careful notes on that 1989 holiday classic, "National Lampoon's Christmas Vacation," in which Chevy Chase's lovably hapless Clark Griswold strings 25,000 incandescent bulbs on his house.

"Using the latest data from the US Energy Information Administration, we calculated the cost of both incandescent and LED C9 holiday lights, for good measure," the site notes.

Well, Clark Griswold must've made a mint in his job as "food-additive designer," because decking those outdoor halls is pretty costly if you use incandescents as he did.

Estately surmises it ranges from $2,582 (£2,038, AU$3,461) a month in Louisiana to $7,552 (£5,959 AU$10,127) in sunny Hawaii to power 25,000 incandescent bulbs for 5 hours a day for 31 days. It's a lot cheaper if LEDs are used, ranging from $30 (£23, AU$40) -- in Louisiana and Washington state -- to $86 (£67, AU$115) in Hawaii and $65 (£51, AU$87) in Alaska.

So now that you know, go ahead and strike the harp and join the dedicated decorators' chorus. Yule be the hit of the neighborhood.
