Lextar receives LM-79 and LM-80 accreditation

Vertically integrated LED maker Lextar Electronics Corp of Hsinchu, Taiwan says that its “Photometric Laboratory” has received LM-79 and LM-80 accreditation. According to the firm, this makes Lextar the first LED corporation in Taiwan to be awarded both accreditations.

LM-80 is the Lumen Maintenance assurance for LED packaging. LED lumens (brightness) decay over time, producing light fades or colorcast. LM-80 tests LED packaging at multiple temperatures for 6,000 hours to determine the quality and life of a particular LED. Major international plants at present all use LM-80 as indicators for the quality and life of their LED packages, making it a common testing standard across the globe, says Lextar.

LM-79 is the industry standard procedure for photometric and electrical measurements for LED lighting products. LED lamp manufacturers can test and report through LM-79 to provide an optical measurement value of credibility.

To receive the LM-80 accreditation, Lextar’s 3014 and 5630 LED packages exceeded 6,000 hours of testing over the course of nearly 9 months, and demonstrated a high standard luminous output when subjected to temperatures at 55 and 85 degrees Celsius. The 3014 and 5630 packages offer a high degree of stability and quality, and can be used in bulbs, tubes, down lights, panel lights, advertising light boxes as well as in many other applications.

Lextar’s CoB product series is also undergoing LM-80 testing, with accreditation expected next year.
