The Appleton IHC Series is an Industrial High Lumen Output Luminaire designed to illuminate heavy industrial facilities with ceiling heights of 50 feet or greater, with a best-in-class maximum ambient temperature rating of 75 °C or 167 °F. Designed as a flexible solution, the IHC series offers various lumen output levels and can easy retrofit legacy 1000 and 1500-Watt HID fixtures. It has four light distribution patterns with specially designed optics to ensure the maximum amount of light is pushed downward to provide safe light levels with the least number of fixtures at a variety of mounting heights and a wider range of applications.
