From the press release:

“Lights, Camera, Christmas!” is a new competition series in which 16 families from across America will decorate their homes to the extreme for Christmas – in ways that would certainly make even Clark Griswold envious – for a $50,000 Grand Prize. The series will air this December on ABC.

In the first nationwide Christmas lights competition of its kind for television, four families will compete each week to transform their homes for the holidays in just 21 days. These 16 families were chosen through an extensive nationwide search, based on their previous elaborate Christmas light displays, incredible choreography and over-the-top designs. The four finalists will be flown to a surprise finale city to compete for the $50,000 Grand Prize.

Brady Connell and Max Swedlow (both “Extreme Makeover: Home Edition”) are Executive Producers for the series. Executive Producers for FremantleMedia North America are Thom Beers and Jennifer Mullin.
