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 3 withstand hazardous material under normal operating conditions. Housed in lightweight aluminum, they have built in LEDs that last longer, are more efficient, and generate less heat than other light technologies.
Lights with a cool appearance highlight white/blue tones that are good for inspecting.
All are IP66 rated for protection from washdowns. NEMA 4X rated lights protect their parts from corrosion.

Corrosion-Resistant Washdown Bay Lights


Illuminate harsh, wet areas, even outside in extreme weather—these lights are often used on ship building ports. Rated NEMA 4X and UL marine listed, they’re sealed against heavy rain and washdowns, and they won’t corrode from salt water or cleaning chemicals. They’re also IP rated to stay sealed in dusty conditions. And with a durable glass lens, they’re rated IK08 for impact resistance. They’ll work in temperatures from -40° F to 145° F. Bright enough for environments that require high visibility, these lights have a cool appearance that highlights white and blue tones.
A quick-connect mount lets you wire these lights to an outlet box without having to hold them in place. First, wire the mount to your outlet box with a 3/4" conduit connector. Then twist the light into the mount to lock it in place.
These lights are DLC (DesignLight Consortium) listed, so they’ve been tested to confirm their energy efficiency. They’re also CE Marked to meet European safety standards.

Hazardous Location Large-Area Floodlights

These lights are UL listed for Class I, Division 2, Groups A, B, C, and D for 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. They can be hardwired to operate on any of the voltages listed. They require a metal halide bulb (sold separately). These floodlights cannot be sold to California due to local energy efficiency regulations.

Explosion-Proof Dock Lights

Safe to use in areas with ignitable concentrations of flammable or combustible gases, vapors, liquids, and dust, these lights are rated NEC Class I, II, and III. Their housing contains fire and sparks, so they won’t ignite what’s in your environment. They’re rated T4A, an NEC hazardous location temperature classification. This means their surface temperature stays below 248° F to prevent them from reacting with nearby flammable substances. These lights swing out from the wall, and their head tilts and swivels to illuminate loading docks and trailers. UL marine listed and NEMA 4X rated, they stand up to salt water and other corrosive liquids, and they’re sealed to withstand washdowns.
Their lens is tempered glass, so it resists scratches and impact during loading and unloading. Since the lens is clear, the lights give focused illumination that is useful for tasks and spot lighting. The LEDs emit a cool light that highlights white and blue tones and has a brighter appearance than neutral light.
Hazardous location environmental ratings indicate where manufacturers have included safety features in products to facilitate their safe use in hazardous environments. Before selecting a product for a hazardous location, ensure it is rated for your environment.
