Lumileds shows record Lifetime Data For Mid Power LEDs
Earlier this month Lumileds announced breakthrough LM-80 test results for its Luxeon 3535L mid power LED line. Completing 10,000 hours of LM-80 testing at 55degC, 85degC and 105degC, Lumileds reported that it exceeded lumen maintenance requirements of the US Environmental Protection Agency's Energy Star program, qualification by the DesignLights Consortium (DLC), as well as other emerging specifications.
Projections show that the devices will maintain 90 percent of their initial lumen output (L90) for a minimum of 60,000 hours at a 200mA drive current and Ts temperature of 85degC. Exceptional lifetimes were extrapolated at all test conditions, says the company. This performance means Luxeon 3535L LEDs can operate in an LED fixture for 13 years while maintaining at least 90 percent of their initial brightness.
"Based on our experience as a leading high power LED manufacturer, we were able to utilise our technology know-how to create the Luxeon 3535L, which has become a top choice among discerning LED lighting manufacturers," said Rahul Bammi, VP of product management and 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).
