For years, New Jersey children have gone to the Liberty Science Center to learn more about nature, humanity and technology. So it makes sense that science center officials recently decided to install new lighting technology, retrofitting more than 1,700 incandescent bulbs with LED lights.
 
Among the lights that were replaced were 1,500 energy-wasting 90-Watt incandescent PAR38 bulbs. Those lights were replaced with 1,500 Cree LRP-38™ LED lights. 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.
 
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. When factoring in maintenance savings because of the long life of the LED lights, science center officials say they’ll save an estimated $119,825 per year in energy and maintenance costs.
