Linear Bay Lights



With a lower profile design than other bay lights, linear bay lights mount closer to ceilings, providing more room for racks or shelving. Use them in large, open areas such as warehouses and manufacturing spaces where the ceiling is up to 40 ft. high. Rated for use in damp locations, these lights withstand humidity and moisture. They can be hardwired to operate on any of the voltages listed.
Style A and C lights require suspension hardware (sold separately), which includes two wire rope slings with hooks and two wire rope clamps. No tools required—adjust the length of the suspension hardware and tighten the clamps to secure. Style B lights come with suspension hardware: two V-hanger brackets and two 36 in. chains.
Lights with built-in LEDs last longer, are more efficient, and generate less heat than fluorescent lights. They emit a neutral white light often found in workspaces. All have a lens that disperses light evenly.
Lights without bulbs work with tubular fluorescent bulbs (sold separately).
Lights with an aluminum housing are lightweight and resist corrosion better than those with a steel housing. Lights with a steel housing are more durable than lights with an aluminum housing.

Linear Ceiling Lights
Link these lights together to create different shapes with a sleek look. Also known as slot lights, they’re often found hung from, mounted to, or recessed into ceilings in offices and cafeterias. Any shape you form will be lit up continuously because the L, tee, and X connectors (sold separately) light up. Straight connectors (sold separately) link two lights together from the inside. There’s no need for tools for any connections. Remove the end panels, push together the electrical cables, and snap the light in place. You can link up to 32 feet of lights together with a single power connection. These lights include all necessary hardware for mounting.
Choose between a warm or neutral light appearance on the power supply to match existing lights. Each LED is inspected to make sure there are no visible differences in temperature and brightness, so you can combine multiple lights within the same space.
Suspension lights can send up to half their light upward to reduce glare, prevent eye strain, and make your space appear larger. Use them against a white ceiling for the best effect.

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.

Retrofit Hazardous Location Round Bay Lights

Upgrade your existing hazardous location bay lights to energy-efficient LEDs. Choose a light that matches the model already in place—they’ll fit into your existing hood and connect to the wires already in your conduit. Safe to use in areas with combustible concentrations of gases, vapors, dust, and fibers, these lights are rated NEC Class I, II, and III.
These lights even stand up in wet and outdoor locations. Rated IP66 and IP67, they withstand washdowns and submersion in water. They’re also dust tight. For resisting salt water and other corrosive liquids, they’re UL marine listed and NEMA 4X rated. They’ll keep shining in extreme temperatures, from -40° F to 145° F.
Style A have mounting holes that align perfectly with Crouse-Hinds mounting hoods—no mounting adapter required.
Style B and C require an adapter (sold separately) to fit into Crouse-Hinds, Killark, and Mercmaster mounting hoods. Style B are rated IK08 for impact resistance against accidental bumps.

Explosion-Proof Linear Bay Lights
Safely light up chemical processing plants, mining operations, and other large areas where combustible gases and dust are present. These lights have an explosion-proof housing that contains sparks and flames, so they won’t react to nearby hazards. With a T4 classification, their surface temperature stays below 275° F to avoid igniting flammable substances. Because they’re totally sealed, they also work well in wet, dusty, and corrosive environments—they’re IP and NEMA rated, and UL marine listed.
Mount them to your ceiling or other surface with the included adjustable bracket. The bracket pivots, so you can aim the light where needed. To suspend them from your ceiling, combine a pendant mount and junction box (sold separately).

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.

Retrofit Washdown Round Bay Lights

Upgrade your existing bay lights to energy-efficient LEDs without replacing your mounting hood or conduit. These lights are NEMA 4X rated, so they’re sealed to withstand sprayed water and cleaning chemicals from washdowns. They’re also UL marine listed to resist corrosion from salt water. IP66 and IP67 rated, they’re dust tight. Even in extreme temperatures, from -40° F to 145° F, they keep shining.
Style A have mounting holes that align with Crouse-Hinds mounting hoods—no mounting adapter required. Styles B and C require an adapter (sold separately) to fit into Crouse-Hinds, Killark, and Mercmaster mounting hoods. Rated IK08 for impact resistance, they’re strong enough to take a hit without cracking.

Portable Bay Lights


Light up large, open rooms where you need a quick setup and takedown, such as a room under construction. Just hang these lights from a ceiling up to 30' high and they’re ready to go. Connect up to 10 lights on a single circuit. The brighter the light, the further you should space them apart. All withstand humidity and moisture, so you can use them where it’s damp.
Lights with an outward beam direction have straight sides, so they’ll direct some light to the ceilings and walls of your facility. Rated IP64, they’re sealed against splashing liquid and dusty conditions.
Lights with a downward beam direction have angled sides, so they’ll direct more light towards the floor than lights with an outward beam direction.
