Software engineer John Storms says his light display is different from Clark Griswald's.
"Technically Clark Griswold had 25,000 lights on his house and this we only have 14,260 exactly," Storms said.
They're almost all LEDs run by a computer.
"The thing is, I couldn't afford to power Clark Griswold’s house," says Storms.
However, he can afford his display. He buys the lights on sale and saves a huge amount on his electric bill.
"They pull about 11.64 amps and if I were using normal iridescent lights that would be between 47 and 75 amps."
Austin Energy Program Coordinator James Parker gives us another idea of the energy saved by using LEDs.
"I have a strand of 50 C3 LEDs they're putting out right now, 2.8 watts,” Parker demonstrated. “Over here I have a strand of 50 C7 incandescent Christmas lights and they're showing 253 watts."
He estimates that if you have Christmas lights on for 300 hours a year (10 hours a day for 30 days), you would save at least $5 a strand by using LEDs.
"The pay back in the electric bill is really quick," Storms tells FOX 7. He uses a special software program to run his light show. The lights are connected to 32 channels. The program allows him to go in channel by channel to turn the lights on and off, and run it all to music.
The light show is on display from Thanksgiving through Christmas from 6-9 p.m. The show is synched to music played on radio station 106.9. Storms' lighting display is located in Round Rock.
