Cree Brings LED Lighting to Largest Commercial Lighting Market

Cree, Inc., a market leader in LED lighting, announces the volume availability of the LR24, a 24-inch square, recessed LED luminaire.

The LR24 delivers high-quality, energy-efficient light for suspended-ceiling applications traditionally addressed by linear fluorescents, also known as lay-ins or troffers.

The LR24 is the newest addition to the Cree family of recessed LED fixtures and delivers the uniform, high light levels required for offices, schools, hospitals and retail environments while consuming less electricity than most linear fluorescents.
   
The LR24 features superior color rendering, with a color-rendering index (CRI) of 92—compared to a CRI of 70 to 80 for fluorescents. It is also dimmable to 5 percent with standard protocols—providing additional design flexibility and further energy-saving potential.
  
“With the addition of the LR24, we can light an entire office using Cree LED fixtures,” said Neal Hunter, Cree president of LED lighting. “You can have it all—superior energy efficiency, natural-looking light, no toxic mercury and an ultra–low maintenance system, designed for 50,000 hours. The volume availability of the LR24 builds on Cree’s success to-date, as we’ve already installed more than 1,000 early-production LR24s in various national-account projects.”
  
“We have installed LR24s on one floor at the U.S. Federal Reserve in Washington, D.C. as part of our ongoing energy-efficiency program,” said Chris Jennings, U.S. Federal Reserve, plant manager. “The graphic designers in the department love the uniformity and the color rendering of the new lights. We are impressed with the amount of light delivered by the LR24, and we look forward to evaluating additional Cree LED lighting products in other applications within the Federal Reserve.”
  
The use of LED lighting can be a great advantage in gaining LEED (Leadership in Energy and Environmental Design) certification. “LED lighting is becoming an exciting design element in sustainable design projects,” said Tom Liebel, AIA, LEED AP, Associate Principal at Marks, Thomas Architects. “Furthermore, the use of LED lighting for general illumination can dramatically lower a building’s energy-density, allowing an architect to re-introduce accent or decorative lighting—something that is sometimes sacrificed in buildings pursuing LEED certification today.” The LR24 delivers high light levels at only 0.5 to 0.75 watts per square foot.
  
With an elegant 24-inch square form, the LR24 offers architects and designers a modern lighting aesthetic, freeing them from the design constraints of linear-fluorescent technology. The innovative lens is recessed above the ceiling—reducing glare and creating an attractive and comfortable environment.
  
The LR24 has already been recognized for its superior efficacy in the 2008 Lighting for Tomorrow solid-state lighting competition, organized by the American Lighting Association, the U.S. Department of Energy (represented by Pacific Northwest National Laboratory) and the Consortium of Energy Efficiency.
