Semi LEDs, with cooperation of Integrated System Technology(IST), is proud to announce that its S35 product line has successfully completed the requirements of the stringent 6000 hour lumen maintenance test (LED high bay light) and the results showed an extrapolated lifetime of up to 50,000 hours.

SemiLEDs’ S35 series is the first product to pass the LM-80 after IST’s received the accreditation from the US Environmental Protection Agency (EPA). The results of other products will be down the pipeline, including the newly launched C35 family. In the Asian market, SemiLEDs is one of the few packaging companies that passed the test on a certified third party basis.

“LED components are sensitive to heat and most failures in lighting fixtures involves thermal mistreatment. Therefore, verifying the degradation at various temperatures is very critical.”Kevin Tsui, VP of Reliability Engineering Department of IST.

Kevin Tsui further explained that LM-80 is required by led high bay lighting and involves the collection of data based on 3 different case temperatures for over at least 6000 hours. The lumen maintenance requirement is also defined. This test will provide standardized quality assurance and quality certification for lighting fixture manufacturers and LED manufacturers respectively.
