We installed the LED EXPLOSION PROOF LIGHTINGS certified by ATEX and IEC Ex from SHENZHEN KHJ SEMICONDUCTOR LIGHTING CO LTD in our Project COGEN LIGHTING IMPROVEMENT AT PGB UTILITIES KERTIH since 2016 until 2019 and were satisfied with the performance. The brightness improved tremendously and the installation easy.
