Can't tell for sure but based on the shape and size of the lights and the size of their bezels I am fairly confident that they're AmericanDJ Punch LED Pros... If I'm right it would make the measurements for the facade 36" for the wings and 72" for the center panel.
The Punch LED Pros are an older product and can be harder to find; You'd be better off going with Chauvet ColourStrip Minis or ColorKey KasBars or something if you're trying to recreate this effect.
