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 T_s 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.

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—the LUXEON 3535L. ”Based on our experience as a leading high power LED manufacturer, we were able to utilize our technology know-how to create the LUXEON 3535L, which has become a top choice among discerning LED lighting manufacturers,” said Rahul Bammi, Vice President of Product Management & Marketing. This sentiment is echoed by Titan LED, a manufacturer of LED tubes, who recently commented on the LUXEON 3535L LM-80 data. "The reliability of the Lumileds LUXEON 3535L gives me confidence to rate my products with long lifetimes. Titan LED’s customers appreciate our quality, which is why we choose Lumileds LEDs," said Brian Hennessey, President and CEO of Titan LED (Simi Valley, CA).

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 color temperature and CRI options, these standard format LEDs are perfectly suited for applications such as troffers, downlights, low bay and TLEDs. In addition, the LUXEON 3535L packages are offered at three performance and price levels—the LUXEON 3535LS, 3535L, and 3535L HE—giving fixture designers ultimate flexibility.
