Cree, Inc. has outfitted the National Aeronautics and Space Administration (NASA) headquarters, a leased facility in Washington, with CR Series LED troffers. The LED installation is part of a renovation of the 600,000 square-foot building. More than 1,300 of the lighting fixtures have been installed.

Piedmont Office Realty Trust, owners of the NASA headquarters building, expects the new fixtures to deliver energy savings of 52 percent over the previously installed T8 fluorescent fixtures. An additional 5,200 Cree CR22 troffers are planned to complete the lighting upgrade.

“We originally considered replacing the existing T8 fluorescent tubes with T5 fluorescents, but after testing Cree’s CR22 LED troffer, we knew it was the best solution for this installation,” said Tony Roberts, senior chief engineer supporting Piedmont Office Realty Trust.

The new fixtures are designed to last for more than 50,000 hours, twice the lifetime of comparable linear fluorescents, according to the company. Installation of the Cree linear luminaires enabled a reduction in fixture count by 10 percent, as well as reduced maintenance and operational costs for the NASA headquarters. The new lighting system also supports the objective to achieve LEED Silver certification for the facility. The photo to the right shows an NASA office corridor with the new fixtures.

The CR22 troffers feature integrated Lutron EcoSystem dimming technology and a Lutron Quantum lighting control system. The controls provide the flexibility needed to suit the lighting to the occupant. The system can also extend the LED’s lifetime.

Cree's product families include LED fixtures and bulbs, blue and green LED chips, high-brightness LEDs, lighting-class power LEDs, power-switching devices and RF devices. The company offers mercury-free LED lighting, lighting-class LEDs and semiconductor products for power and radio-frequency (RF) applications.
