Lumileds announced breakthrough LM-80 test results for its LUXEON 3535L Mid Power LED line. Completing 10,000 hours of LM-80 testing at 55˚C, 85˚C and 105˚C, Lumileds has exceeded lumen maintenance requirements of the U.S. Environmental Protection Agency’s ENERGY STAR® program, qualification by the DesignLights Consortium™ (DLC), as well as other emerging specifications. Projections based on TM-21-11 show that the devices will maintain 90% of their initial lumen output (L90) for a minimum of 60,000 hours at a 200 mA drive current and Ts temperature of 85˚C. Exceptional lifetimes were extrapolated at all test conditions. This performance means LUXEON 3535L LEDs can operate in an LED fixture for 13 years* while maintaining at least 90% of their initial brightness.
