The long, linear body of these hazardous location lighting fixtures spreads light over a wide area for more coverage per fixture than round lights. They mount to flat surfaces where there's enough space for the larger fixture footprint and illuminate areas with flammable, combustible, or ignitable materials. These hazloc lights keep arcs and sparks contained so that the fixtures won't cause a fire or explosion. They carry class and division ratings as defined by NEC and OSHA for use in locations where specific hazards are present in normal or abnormal conditions. Class I and II fixtures also carry group ratings designating use in locations with specific types of gas, vapor, or dust. LED lights use less energy and typically last longer than other lighting technologies, reducing maintenance and downtime. Fluorescent lights are commonly used in facilities with other fluorescent fixtures where frequent bulb changes are expected as part of regular maintenance.
