BRIGHT IDEA: On Monday night the top of the Empire State Building was bathed in a dazzling display of LED lights, synchronized with R&B star Alicia Keys singing "Empire State of Mind" on nationwide radio.
SEEING THE LIGHT: The LED system has 16.7 million color possibilities, in digital combinations of ripples, sparkles, sweeps and strobes. The old floodlights that lit the building came in only 10 colors.
DARK SECRET: The new lights were tested briefly in the wee hours of Thanksgiving morning, so most New Yorkers were treated to a stunning surprise a few days later.
