Rated for over a decade of use well above 100° F, these linear bay lights long outlast standard facility lights in high heat. They’re often installed in warehouses located in sweltering climates and in fiery manufacturing facilities, such as steel mills.

Style A lights have outer LED modules that can be rotated to aim some amount of light upwards. This creates uplighting, which reduces glare and eye strain. These lights are rated to resist humidity and impact. Hang them from your ceiling using suspension hardware or thread them onto 3/4″ NPT conduit. Add motion sensors for them to turn on automatically. A remote control is required to adjust the default motion sensor settings.

Style B lights are rated IP66 for protection from washdowns. They're also rated IK10—the highest rating for electrical equipment—and offer four times the impact resistance of Style A lights. Mount them using the included bracket and eyebolt.

Style C lights are ETL listed for wet locations. Their pass-through heat sink prevents dust and debris from building up, keeping them cool without the need for cleaning. Install them using the included suspension hardware or with a mounting bracket (sold separately).

With more surface area than round bay lights, these fixtures produce softer light with less glare. Use them to replace old fluorescent lights and illuminate large, open areas with high ceilings. Rated for use in damp locations, these lights withstand humidity and moisture.

Lights with a narrow beam direct light downward, so they’re good for confined spaces such as warehouse aisles.

Lights with a motion sensor turn on when people or vehicles are present. Add a remote (sold separately) to program your sensor’s settings without needing to climb up to the light.

Style A are made of thin, lightweight materials and are the most economical option. They include suspension hardware.

Styles B-D have thermally protected drivers and larger heat sinks than other bay lights, so they’ll last longer at higher temperatures. Their LEDs have a consistent color temperature, which helps maintain a uniform appearance across multiple lights.

Style B lights are compatible with an emergency backup battery (sold separately), so they’ll stay lit for 90 minutes if the power goes out. The battery meets UL 924 standards.

Style C can be mounted with the included suspension hardware or mounting brackets (sold separately). The suspension hardware comes with two wire rope slings with hooks and two wire rope clamps. No tools are required for installation—adjust the suspension length and tighten the clamps to secure. Those with a backup battery stay lit for 90 minutes if the power goes out.

Style D direct some light upward to reduce glare and improve visual comfort. They’re most effective when used with a white ceiling. These lights can be mounted in several ways to fit your space—suspension, ceiling, hook, and conduit mounting hardware is all sold separately.

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.

Mount these lights in large, open areas where flammable and combustible gases may be present, such as during leaks or ventilation failures. These lights are rated for use in NEC Class 1, Division 2 hazardous locations. They meet NEC hazardous location temperature classifications, so their surface stays cool enough to avoid igniting hazardous gases. All are IP rated and UL marine listed, which confirms they also keep out dust and water and resist the corrosive effects of salt water. Mount them to your ceiling or wall with the included bracket.

For additional protection, choose a light rated for more NEC classes. NEC Class II-rated lights protect against flammable and combustible dust. NEC Class III-rated lights protect against flammable and combustible fibers.

Style 1 are IK08 rated—they'll withstand impact. They have a tempered glass lens that resists scratches better than a polycarbonate lens. All are ETL and C-ETL listed to meet U.S. and Canadian safety standards. To hang them from the ceiling, add suspension hardware or combine them with a pendant mount and junction box (all sold separately).

Style 2 meet ABS (American Bureau of Shipping) requirements for use on docks and ships. If you want to mount these to a 2 3/8" dia. pole, add a mounting bracket (sold separately).

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).

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.

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.

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.
