LEDs can operate for 13 years with 90% of their brightness
Lumileds has announced breakthrough LM-80 test results for its LUXEON 3535L mid power LED line. Completing 10,000 hours of LM-80 testing at 55, 85 and 105°C, Lumileds has exceeded lumen maintenance requirements of the U.S. Environmental Protection Agency’s ENERGY STAR programme, 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 200mA drive current and Ts temperature of 85°C.
Exceptional lifetimes were extrapolated at all test conditions. This performance means the LEDs can operate in a fixture for 13 years while maintaining at least 90% of their initial brightness.
Historically, customers have expressed concerns regarding the long-term performance of mid power LEDs. By leveraging its expertise in high power LEDs, Lumileds has developed a line of mid power emitters that demonstrate unparalleled lumen maintenance and reliability.
LUXEON 3535L mid power LEDs have become the go-to choice for a variety of indoor area lighting, high bay and low bay applications. Offered in a range of colour temperature and CRI options, these standard format LEDs are suited for applications such as troffers, downlights, low bay and TLEDs.
