As some of you may know, the Liberty Science Center, an interactive science museum
and learning center. Located in Liberty State Park in Jersey City, [New Jersey](https://greenlivingguy.com/2011/10/third-major-project-from-spi-alliance-with-kdc-solar-results-in-7-mw-solar-facility-in-new-jersey/).
Therefore the center, which first opened in 1993 as New Jersey’s first major state
science museum has science exhibits. Also many educational resources, and the largest
IMAX Dome theater in the United States. Liberty Science Center is also home to the
original _Hoberman Sphere_. It’s a silver, computer-driven engineering artwork designed
by Chuck Hoberman. Chuck is a famous inventor of folding toys and structures.

The most recent green initiative included revamping the facility’s interior. All
for replacing traditional lighting with [energy-efficient LED lighting](https://greenlivingguy.com/2020/04/why-led-lighting-is-a-better-choice-to-go-green/).
Liberty Science Center officials decided to replace more than 1,700 [incandescent bulbs](https://greenlivingguy.com/2020/02/10-energy-saving-technologies-for-homes-you-should-consider/)
with new LED lighting fixtures.

Among the lights replaced, 1,500 energy-wasting 90-Watt incandescent PAR38 bulbs.
In its’ place! Can you say 1,500 [Cree](https://www.creelighting.com/) LRP-38™ LED
spotlights. Likewise it’s specifically designed for displays in [museum](https://greenlivingguy.com/2011/03/the-smithsonian-and-the-getty-testing-msi-led-lighting-for-museums/)
environments. Many of the exhibits are now lit with 12 Watt LRP-38 LED lights.

So my goodness they consume much [less energy](https://greenlivingguy.com/2010/03/green-guru-guides-do-it-yourself-energy-audits-simple-solutions-to-reduce-your-utility-bill-and-carbon-footprint/)
while delivering great 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
almost 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 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](https://greenlivingguy.com/2020/04/cree-led-street-lighting-delivers-57-million-total-lifetime-savingsto-the-nations-largest-township/).
