Explosion proof high bay lights provide overhead illumination in hazardous location facilities with high ceilings, typically ranging from 20 to 50 feet. These fixtures are UL listed for Class I Division 1 and Division 2 (or Zone 1 and Zone 2) environments, making them suitable for petrochemical plants, refineries, offshore platforms, and chemical processing facilities where flammable vapors may be present at ceiling height.
Lumen output for explosion proof high bays typically ranges from 10,000 to over 40,000 lumens depending on fixture size and application. LED versions replace legacy metal halide and high-pressure sodium high bays with significantly lower energy consumption and reduced maintenance intervals, which is a meaningful operational advantage in hazardous locations where re-lamping requires special procedures and shutdowns.
Most models are available in UFO (round) and linear form factors and are listed for both indoor and outdoor wet location use.
