New York City’s famous landmark, the Empire State Building, is used to being lit up for events – Christmas, Election Day, St. Patrick’s Day, etc. But it’s never seen anything quite like this. The tower now has a new LED lighting system.

“The state-of-the-art dynamic lighting system from PCK is unique to ESB and allows customized light capabilities from a palette of over 16 million colors in limitless combinations along with effects previously not possible such as ripples, cross-fades, sparkles, chasers, sweeps, strobes and bursts. In addition to greater control and management of the lighting, the new computerized system will deliver superior light and vibrancy levels in real-time, unlike the previous floodlights,” says a release.

Last night, the debut light show featured two songs by NYC native Alicia Keys.

People were able to follow along with the light show by tuning their radio dials to one of four different stations, all broadcasting the Alicia Keys’ songs: “Girl on Fire” and “Empire State of Mind.”

“The Empire State Building’s lights are the international icon of the New York City skyline. We use our tower lights to partner with select charities, organizations, and events around the world,” said Anthony E. Malkin, President of Malkin Holdings which supervises the Empire State Building. “‘Philips Color Kinetics’ new LED lights were installed over the summer and have been set at the color and intensity of the incandescent lights they replaced. As of tonight, our lights’ full range and intensity will be brought to life, forever changing the New York skyline. We wanted to celebrate with and thank New York City and our global audience with a specially choreographed, custom light show.”
