Also known as troffers, these lights fit most standard drop-ceiling grids, so they’re often used in indoor spaces such as offices and storage rooms. They can be hardwired to operate on any of the voltages listed.

Lights with a parabolic lens are reflective to direct light downward and reduce glare. They require fluorescent bulbs (sold separately).

These fixtures disperse light from the top, bottom, and side to produce ambient lighting. They mount to the wall so they're often used in enclosed spaces such as stairwells, hallways, and storage rooms. Rated for use in damp locations, these lights withstand humidity and moisture. The lens is grooved or smooth and frosted to disperse light evenly.

Lights without bulbs work with tubular fluorescent bulbs (sold separately).

These lights are rated for protection against washdowns. A sealed lens keeps moisture out.

Style C have a tubular lens that allows light to shine from all directions. The lens is acrylic so it won’t turn yellow over time. Lights are NSF C-2 rated for protection against washdowns in food processing areas.

Lights without bulbs work with tubular fluorescent bulbs (sold separately).

These lights are UL listed for hazardous locations where flammable/combustible gases, vapors, and liquids may be present. They are rated NEMA 4X/IP66 for protection from corrosion and washdowns. Lights have a sealed lens and corrosion resistant housing. They can be hardwired to operate on any of the voltages listed.

Style 1 can be used where ignitable concentrations of hazardous material occur infrequently, such as in the case of an accidental spill or failure of a ventilation system. Rated for Class I, Division 2, Groups A, B, C, and D, these lights withstand acetylene, hydrogen, ethylene, and propane.

Style 2 can be used 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; 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.

Fastener-mount lights have a stainless steel housing that resists corrosion better than aluminum. They require tubular fluorescent bulbs (sold separately). They have an acrylic lens that won't turn yellow over time.

Thread-on lights have a lightweight aluminum housing. They include bulbs with a cool light appearance, which highlights white/blue tones and is good for inspecting. Lights have two female connections—thread onto 1/2 NPT conduit to suspend lights from the ceiling.

Mount lights in recessed spaces so the lens is flush with the wall. These fixtures are ETL/C-ETL listed for Class I, Division 2, Groups A, B, C, and D; and Class II, Division 2, Groups F and G for use where ignitable concentrations of hazardous material occur infrequently, such as in the case of an accidental spill or failure of a ventilation system. They withstand acetylene, hydrogen, ethylene, propane, carbonaceous dusts, and nonconductive dusts. These lights are often used in freestanding buildings, such as paint spray booths, so the back opens like a door for changing light bulbs from the outside. They can be hardwired to operate on any of the voltages listed. They work with tubular fluorescent bulbs (sold separately).

These LED lights have an air-tight seal to protect against contaminants. The lens is prismatic to disperse light evenly. Lights can be hardwired to operate on any of the voltages listed. To install, drill mounting holes and seal with silicone (not included).
