Lumileds reported that its Luxeon 3535 L has completed 10,000 hours of its LM-80 testing. The 10,000-hour testing was at 55˚C, 85˚C, and 105˚C. The company says that the LED exceeded lumen maintenance requirements of the U.S. Environmental Protection Agency’s ENERGY STAR® program. Also, the LED exceeded the performance qualifications of the DesignLights Consortium™ (DLC), in addition to other emerging specifications.
According to Lumileds, the TM-21-11 data project 90 percent lumen maintenance (L90) for a minimum of 60,000 hours at 200mA drive current Ts temperature of 85˚C. This result means that the Luxeon 3535 L can maintain 90 percent of its original brightness for a minimum of 60,000 hours. 60,000 hours translates to more than 6.84 years of 24 hr/day operation.
The company noted that in the past, customers expressed concerns about the long-term performance of mid-power LEDs. However, Lumileds contends that its mid-power Luxeon 3535L LEDs have demonstrated unparalleled reliability and lumen maintenance.
