A series of man-made waterfalls installed around New York Harbor were lit using LED lighting fixtures to simulate the effect of moonlight on the water.
The New York City Waterfalls public art installation, by artist Olafur Eliasson, comprised four man-made waterfalls in the New York Harbor situated along the shorelines of Lower Manhattan, Brooklyn and Governors Island. One of the key features of the waterfalls was their use of LED lighting behind the water flow to simulate the effect of moonlight.
The Waterfalls ranged from 90 to 120-feet tall and were on view from June 26 through October 13, 2008. The project was commissioned by the non-profit Public Art Fund in collaboration with the City of New York. Each waterfall pumped 35,000 gallons of water per minute from the East River to the top of a scaffold. As the water flowed over the lip of the falls it is illuminated by LED fixtures. Each waterfall utilized a continuous row of assembled 5 feet sections of LED fixtures, with a mixture of cool and warm white LEDs controlled by 3 separate channels. The total wattage was 300W per 5 ft. section at 100% output, while the actual operating load was 15-25%, depending on the site. Light from the LED fixtures grazed the back of the water, penetrating the flow and accentuating the effect of wind gusts and changes in water flow rate. A custom baffle just below the LED source prevented glare at normal viewing angles.
