DURHAM, N.C., April 2, 2009 (GLOBE NEWSWIRE) -- Cree, Inc. (Nasdaq:CREE) has been awarded ENERGY STAR(r) qualifications for its LED downlights. The product line, including the LR6, LR5 and LR4 downlights, has demonstrated LED lifetime and fixture efficacy that qualifies for the stringent commercial rating, as well as the residential rating.
ENERGY STAR is a joint program of the U.S. Department of Energy (DOE) and the U.S. Environmental Protection Agency (EPA) that helps consumers and organizations save money and protect the environment by promoting energy-efficient products. Products earning the commercial ENERGY STAR qualification must meet extended lifetime criteria, which is 40 percent longer than residential standards.
"Being rated for both commercial and residential applications is especially significant since more than three-quarters of the LED lighting we are deploying today is in commercial installations," said Neal Hunter, president, Cree LED Lighting. "Cree also provides the highest color rendering of any ENERGY STAR-qualified LED downlight. In stark contrast to compact fluorescent devices that contain toxic mercury, Cree's non-toxic LED fixtures deliver better efficiency and render colors such that the user doesn't have to compromise their lighting experience."
The Cree LR6 recessed downlight is available and qualified in two color temperatures (2700K and 3500K), and boasts efficiency of more than 54 lumens per watt with lumen output of 650 lumens -- higher than any other qualified recessed downlight. The LR6 was the first recessed downlight to receive the ENERGY STAR commercial qualification.
The Cree LR4 and LR5 recessed downlights are available and qualified in two color temperatures -- 2700K, with a CRI of 94 and 3500K, with a CRI of 91. The LR4 product line is also available in two shield angles, 15 degree and 30 degree.
The Cree family of LED downlights excels in delivering beautiful, efficient LED light in a manner that surpasses even the most stringent ENERGY STAR standards, as set out in the SSL ENERGY STAR 1.1 criteria for Category A: Recessed Downlights.
