LED ribbons, bows and tiaras deck the Cartier store on the corner of 5th Avenue and 52nd Street. The festive lighting scheme includes several LED features designed by the London-based Metropolis Group of Companies and manufactured at its facility in Wales. Halfway up the building, two pieces of red "ribbon" wrapping the entire building meet at a 14-foot-wide LED bow, while two giant LED tiaras measuring 5 by 16 feet and 5 by 16 feet, sit above the building's two public entrances on 5th Avenue and 52nd Street.The entire display contains over 17,000 LEDs, including 2,340 red Luxeon LEDs from Lumileds in the ribbon, 1000 white Luxeons in each tiara and a mixture of red-and-hite 5-mm LEDs from Plus Opto. The tiaras and bow were built by Met3, Metropolis's LED-manufacturing operation in Swansea, Wales. The display was built in an 8-week period before being switched on in November.
