Following 9-11 and the collapse of the World Trade Centre, The Empire State Building once again became Manhattan’s tallest building. Construction is well underway on the WTC’s replacement, and on April 30th 2012 the new No.1 World Trade Center once again become New York’s tallest structure.
The Empire State Building has been a Manhattan landmark since 1939 and is always lit during the hours of darkness. Its light shows are as legendary as they are spectacular, and it has recently brought these up to date by replacing the existing 400 incandescent lamps with 1200 Philips Color Kinetic led luminaires.
The old lights could display 10 colours – the new leds can display a 16 million. The led arrays will be computer controlled to allow lighting effects such as “ripples, cross-fades, sparkles, chasers, sweeps, strobes and bursts”. The system cost several million dollars to install but uses only 25% of the energy of the previous lights. It will recoup installation costs within 6 years.
