Lextar is the only vertically integrated LED company in Taiwan; its Photometric Laboratory has also become the only one throughout the island and is also one of the few in the world at the same time to become accredited with LM-80 packaging testing approval and LM-79 lighting product testing. In the future, Lextar will be able to use its own laboratory for product testing, which will simplify testing procedures, decrease time and lower costs, as well as quicken the company's ability to capture LED lighting business opportunities across the world.
LM-80 is the Lumen Maintenance assurance for LED packaging. LED lumens (brightness) decay over time, producing phenomena such as light fades or colorcast. The LM-80 test approach uses 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. This certification helps downstream lamp manufacturers determine the quality of the pros and cons of LED lighting, and can significantly shorten the verification time needed for customers’ lamp products.
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, which enhances the trust between customers and their products and vendors.
In addition, Lextar’s 3014 and 5630 LED packages have completed 6,000 hours of LM-80 testing over a course of nearly 9 months and are able to remain a high standard luminous output when subjected to temperatures at 55 and 85 degrees Celsius, showing that the products have enhanced their lifespan reliability. The 3014 and 5630 packages have many advantages such as high degree of stability and quality, and can be used in bulbs, tubes, down lights, panel lights, advertising light boxes as well as
