STAFF REPORT LHR: Samsung Electronics has announced that the Samsung LM561B, a high-efficacy mid-power LED package, has been LM-80 certified. LM-80 is a widely observed test for lumen maintenance developed and accredited by U.S. Department of Energys Energy Star programme.
“Through the LM-80 standard testing, we have affirmed that our LM561B package is an outstanding mid-power solution optimized for premium LED lighting applications that demand high efficacy and reliability,” said Bangwon Oh, Senior Vice President of LED Lighting Marketing, Samsung Electronics.
He said that the company expects that the LM561B product lineup will be even more widely accepted for a variety of LED applications with this certification.
Samsung LM561B completed 6000 hours of LM-80 testing, and among the test results, TM-21 data demonstrated an L70 of 93,000 hours under a 150mA driving current at an operating temperature of 85 degrees Celsius.
This means that the Samsung LM561B will maintain at least 70 percent of the initial light output for a minimum of 93,000 hours, which will make the LED light more amenable to applications that require a high level of lumen maintenance.
The Samsung LM561B is designed for LED lighting applications such as LED tubes, LED ambient lighting, downlighting and retrofit lamps, and features 170lm/W light efficacy.
