The round, compact body of these hazardous location lighting fixtures provides a traditional jelly jar look. They match existing lights for general lighting in 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 than incandescent lights and have built-in LED arrays so there are no bulbs to replace. Ceiling-mounted lights take up minimal space in areas with low ceilings. Pendant-mounted lights suspend from high ceilings to bypass overhead ducts or pipes and bring light close to work surfaces. Wall-mounted lights attach to walls in areas where ducts or pipes prevent ceiling mounting.
