Hazardous Location Ceiling Lights


These lights are UL listed or CSA certified for hazardous locations where flammable/combustible gases, vapors, and liquids may be present. They have a sealed lens and can be hardwired to operate on any of the voltages listed.
Styles 1-2 can be used where hazardous material occurs infrequently. They have built-in LEDs that last longer, are more efficient, and generate less heat than other light technologies. Style 1 are housed in durable stainless steel. Style 2 have an acrylic lens that won’t turn yellow over time.
Lights with a cool appearance highlight white/blue tones that are good for inspecting.
All are IP66 rated for protection from washdowns. IP67 rated lights can be briefly submerged. NEMA 4X rated lights protect their parts from corrosion.

Hazardous Location Ceiling and Wall Lights with Guard






Also known as jelly jar lights. These fixtures have a heat-resistant lens and a guard that protects the lens from breaking. They are CSA certified for hazardous locations where flammable/combustible gases, vapors, and liquids may be present. They are rated NEMA 4X for protection against corrosion and washdowns. Lights are sealed to keep moisture out. They can be hardwired to operate on any of the voltages listed. Some work with LED or incandescent bulbs (sold separately).
Styles 1, 2, 3, 5, and 6 can be used in environments where ignitable concentrations of flammable/combustible gases, vapors, and liquids or combustible dust occur infrequently, such as in the case of an accidental spill or failure of a ventilation system, and where combustible/ignitable fibers or flyings are present under normal operating conditions and/or during frequent equipment maintenance or failure. Rated for Class I, Division 2, Groups A, B, C, and D; Class II, Division 2, Groups F and G; and Class III, Divisions 1 and 2, these lights withstand acetylene, hydrogen, ethylene, propane, carbonaceous dusts, and nonconductive dusts.
Styles 4 and 7 can be used in environments where ignitable concentrations of hazardous material are present under normal operating conditions, and/or during frequent equipment maintenance or failure. Rated for Class I, Divisions 1 and 2, Groups C and D; Class II, Divisions 1 and 2, Groups E, F, and G; and Class III, Divisions 1 and 2, these lights withstand ethylene, propane, conductive or metal dusts, carbonaceous dusts, nonconductive dusts, and combustible/ignitable fibers or flyings.

Hazardous Location Bay Lights

Use these lights in large, open areas such as warehouses and manufacturing spaces where the ceiling is up to 30-ft. high. They are ETL and C-ETL listed for Class I Division 2 Groups A, B, C, and D, Class II Divisions 1 and 2, Groups E, F, and G, and Class III Divisions 1 and 2 for use in environments where ignitable concentrations of acetylene, hydrogen, ethylene, and propane occur infrequently, such as in the case of an accidental spill or failure of a ventilation system. With built-in LEDs, these lights last longer, are more efficient, and generate less heat than other light technologies. They produce a neutral light appearance, which creates a balanced environment for general work areas. These lights produce a wide beam of uniform light. Lights can be hardwired to operate on any of the voltages listed. Thread onto 3/4 NPT conduit to suspend lights from the ceiling.
