Cree Introduces the Industry’s Most Comprehensive LED Luminaire Test

Cree Technology Center Achieves NVLAP Accreditation
DURHAM, N.C. --

LED lighting leader Cree, Inc. (Nasdaq: CREE) announces the addition of TEMPO 24 to its comprehensive suite of Cree Services for LED luminaires. The new TEMPO (Thermal Electrical Mechanical Photometric Optical) 24 service combines IES LM-79-08 photometric testing with an extensive set of LED performance tests that surpasses all industry testing parameters and can help ensure total system design and quality. The Cree Durham Technology Center has been accredited by The National Voluntary Laboratory Accreditation Program (NVLAP) and furthers Cree’s commitment to helping LED manufacturers overcome design challenges and bring quality products to market faster.

“LM-79 is a necessary test and has become a requirement for doing business in the Solid State Lighting market,” said Mark McClear, director of global applications engineering, Cree. “TEMPO 24 includes a fully accredited LM-79 test, but goes well beyond this or any currently existing standards.  Cree has identified through our years of SSL experience nearly a dozen other potential problem sources of LED luminaire design.  Our goal is the same as our customers – and their customers as well – quality SSL products that save energy.  TEMPO 24 helps ensure this and gives customers the information they need to design and specify an SSL product with confidence.”

“In my experience, if I had to select a single document that’s had the greatest impact in selling LED light sources to customers, it would be the Cree TEMPO report,” said Pierre van Helden, CEO, LED Lighting SA. “The service provided an independent and thorough review for our products and the results give us the confidence to sell our products with passion—giving our customers the assurance that our products are being designed and produced to the highest international standards.”

TEMPO 24 provides LED luminaire tests that are not offered by any other third-party testing facility. In addition to LM-79 testing which is an approved method for taking electrical and photometric measurements, TEMPO 24 testing includes binning and color point evaluation, chemical compatibility and TM-21 lifetime projection. TEMPO 24 examines all aspects of an LED design and provides customers a true assessment of luminaire performance that can be used to promote and distinguish their product. Every TEMPO service delivers an accurate, easy-to-understand TEMPO report that includes all testing results and relevant performance data.

Cree’s Durham Technology Center NVLAP accreditation (NVLAP lab code 500070-0) ensures that TEMPO measurements are performed according to the Illuminating Engineering Society (IES) approved method for the electrical and photometric measurements of LED lighting – delivering lighting manufacturers consistent, accurate and repeatable measurements for luminaires. NVLAP accreditation signifies that a laboratory has demonstrated it operates in accordance with NVLAP management and technical requirements pertaining to quality systems, personnel, accommodation and environment, test and calibration methods, equipment, measurement tractability, sampling, handling of tests and calibration items, and test and calibration reports. Cree laboratories also work to American National Standards Institute (ANSI) and National Institute of Standards and Technology (NIST) requirements.

Cree currently provides TEMPO Services out of its Cree Technology Centers located in Durham, N.C. and Santa Barbara, Calif. For more information on Cree Services, please visit www.cree.com/tempo. You can also visit Cree at Booth #130 at Lightfair International in Las Vegas, May 9-11.
