April 19, 2013
Date Announced: 19 Apr 2013 UL WTDP reduces the time it takes Seoul Semiconductor to get the UL Mark for products targeted to overseas markets by allowing the company to perform testing in its own laboratories.Seoul Semiconductor (SSC), a global LED manufacturer (, has announced it has achieved qualification for the UL Witness Test Data Program (WTDP) allowing the company to conduct UL tests on LEDs and modules in its own laboratories, under the supervision of a UL engineer. This allows the company to build on its foundation of manufacturing high-quality LED products such as Acrich, MJT, and nPola by adding in-house testing for the international standards that customers require. An added benefit of UL WTDP is speeding product introductions to global markets through the reduction in the time it takes to get the UL mark. Jeong Min Yeong, Chief of the Reliability Team, Seoul Semiconductor expressed, “We will continue to react quickly to the needs of the global LED lighting market as it rapidly grows by focusing on reinforcing our internal capabilities so we can quickly provide high-quality solutions for LED light sources as requested by our global customers."Seoul Semiconductor continues to make improvements to maintain its high-quality standards and its commitment to innovation and customer service. It already holds certifications to ISO/IEC 17025 “General Requirements for the Competence of Testing and Calibration Laboratories” and ISO/TS 16949 “Quality Management Systems” as well as being part of the U.S. Environmental Protection Agency (EPA)’s list of recognized laboratories for conducting LM-80 testing in order to meet ENERGY STAR® requirements for solid state lighting products.
