Liberty Science Center Saves Real Cash Using Cree LEDs

As some of you may know, the Liberty Science Center is an interactive science museum and learning center located in Liberty State Park in Jersey City, New Jersey. The center, which first opened in 1993 as New Jersey’s first major state science museum, has science exhibits, numerous educational resources, and the largest IMAX Dome theater in the United States. Liberty Science Center is also home to the original Hoberman Sphere, a silver, computer-driven engineering artwork designed by Chuck Hoberman, a famous inventor of folding toys and structures.

The most recent green initiative included revamping the facility’s interior by replacing traditional lighting with energy-efficient LED lighting.  Liberty Science Center officials decided to replace more than 1,700 incandescent bulbs with new LED lighting fixtures.

Among the lights that were replaced were 1,500 energy-wasting 90-Watt incandescent PAR38 bulbs. In their place are 1,500 Cree LRP-38™ LED spotlights, specifically designed for displays in museum environments. Many of the exhibits are now lit with 12 Watt LRP-38 LED lights, which consume significantly less energy while delivering beautiful light. The LRP-38 is also designed to last 50,000 hours and produces little heat, saving on air conditioning needs and related costs, and emits virtually no ultraviolet rays, which can help protect priceless objects featured in the museum.

The Liberty Science Center also replaced 250 60-Watt incandescent bulbs with 11-Watt LED lights. Additionally, a total of 30 50-Watt MR16 incandescent lights were replaced with 5.5 Watt LED lights.

In all, officials at the science center estimate that the museum will see its energy consumption reduced by nearly 625,000 kilowatt-hours each year and nearly $120,000 per year in energy and maintenance costs.
