CHF, CHG Recessed HID Cleanroom


The Fail-Safe CHF/CHG is designed to deliver highly efficient HID lighting to clean room areas. These units are ideal for ceiling heights up to 18 ft. Lower wattages are also available for standard 8 ft. and 9 ft. ceilings. Units are enclosed and gasketed to protect against the chance of foreign matter entering high-tech environments through the light fixture. The CHF outside, flanged door is designed to work with conventional sheet rock or plaster ceilings. Door frames feature a gasket design that eliminates ledge or crevice exposure, preventing the harboring of contaminants. Suitable for I.E.S. Class 100 (M3.5) and above. It is UL/CUL listed for wet locations.
