we are very familiar with the quality of performance

Shown at the Cree booth, #149 at Lightfair 2010 in Las Vegas, the LR24HE is 30 percent more efficient than the best 2-foot-by-2-foot fluorescent troffers and 15 percent more efficient than the led high bay light fluorescent troffers. The LR24HE uses Cree TrueWhite? Technology to deliver 3200 lumens at 3500 K with a 90 CRI. It is designed to last at least 50,000 hours.

“By using the LR24HE, which is the most efficient product for general illumination, lighting designers and architects now have the freedom to reintroduce accent and decorative lighting and still meet energy codes or achieve LEED points,” said Gary Trott, Cree vice president market development, LED Lighting. “Cree continues to leverage TrueWhite Technology to deliver breakthrough new performance levels.

announces it is extending the warranty on its entire family of fixture products to five years. Lengthening the warranty lets customers know that Cree stands behind the long-term performance and reliability of our fixtures.Ty Mitchell, Cree vice president and general manager, LED Lighting said that they have almost 20,000 hours of real-world data on products from their early installations nearly three years ago, and the performance is rock solid.

Professor Peter Parbrook, who has been appointed to lead the GaN growth activity at the Tyndall National Institute using strategic funding from Science Foundation Ireland, comments: “From our existing AIXTRON reactors we are very familiar with the quality of performance and engineering available with their tools. There are many reasons why we opted for a LED high bay lighting reactor for our GaN programme: for instance the flexible reactor configuration which includes gap adjustment. Plus we can work with a range of different substrate sizes to suit our various research projects. Inherently, the tool also has high growth uniformity and we are looking forward to using the ARGUS pyrometric system to give us precision in-situ monitoring and process control.” The growth tool will complement Tyndall’s existing expertise in the theory of GaN photonic materials and fabrication of GaN based devices.
