Fulham Co. Inc., a leading supplier of lighting sub-systems and electronics for commercial and specialty applications, announced that its ThoroLED Universal Voltage Highbay Retrofit Kit (part TRMUNV220ACXXXA), which was introduced early this year as a UL-classified retrofit kit for field installations, has now also been approved for UL listing for use as a retrofit luminaire for renovation projects. In addition, the Highbay Retrofit kit is a DesignLights Consortium (DLC) qualified system under Retrofit and Luminaire, which makes utility rebates more accessible. The ThoroLED Highbay Retrofit kit is suitable for both acrylic highbay and lowbay installations, such as warehouses, hangars, gymnasiums or any building where 400-watt metal halide (HID) luminaires are normally used. The surface-mounted LED driver can handle 120V to 277V input, and the driver can be programmed to optimize power consumption and lumen output. The retrofit kit also has a built-in heat sink with integrated thermal management. The kit can be installed to upgrade an existing highbay luminaire in five to 10 minutes with four-point installation.
