Also known as troffers, these lights fit flush into most drop-ceiling grids. They’re fully sealed with an airtight gasket, so they’re rated IP65 for protection against low-pressure washdowns, humidity, and dust. Install them anywhere that requires frequent cleaning, even an ISO Class 5 clean room. They also meet NSF/ANSI 2, so you can use them in food processing areas with splashing liquid. These lights won’t shatter and contaminate your area—they’re rated IK10, the highest rating for impact protection. And since they’re IC rated, you won’t risk a fire if you install them in direct contact with insulation.

Casting a neutral light dispersed by a frosted lens, these lights won’t cause glare on equipment. The lens is made of acrylic to resist scratching and yellowing.

Illuminate areas that need frequent cleaning, such as food processing lines, with long rows of lights. Rated IP65, these lights have a sealed lens and liquid-tight end caps that protect them from low-pressure washdowns and dust. They also meet NSF/ANSI 2 for splash zones, so they’re safe to use in food areas with splashing liquid. These lights won’t shatter and contaminate your area—with a durable polycarbonate lens, they’re rated IK08 for impact resistance. Adjust the light appearance and brightness with the included remote.

When creating a run of lights, you’ll need connectors between the lights and a power cable. The connectors don’t require any wiring—just remove the end cap and insert the connector. Cable connectors let you space out the lights. In this setup, you’ll need a power cable for every 24 lights at 120V AC. Butt connectors join lights together end-to-end for a continuous row of light. You’ll need a power cable for every 30 4-ft. long lights, or 40 2-ft. and 3-ft. long lights at 120V AC.

Mount these lights to the ceiling with the included brackets. Add mounting hardware to suspend your lights from the ceiling. It includes stainless steel wire rope and connectors.

To control the lights automatically when people enter and exit the area, set them up with motion sensors. The sensors are sealed against washdowns. You’ll need a sensor for every 15 lights. Remote-controlled sensors are operated with a remote control that’s sold separately—one remote will work for multiple sensors. Bluetooth sensors connect to a free app. In the app, you can program and control lights to work in sync or independently.

Illuminate chemical plants, refineries, and other facilities where flammable and combustible gases may be present in the event of a leak or ventilation failure. These lights are rated for use in NEC Class 1, Division 2 hazardous locations. IP or NEMA rated, their seal also blocks out water and dust, so you can use them in damp, humid, and even washdown areas. Use the mounting holes to mount these lights to your ceiling.

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

UL marine listed lights resist the corrosive effects of salt water. ABS (American Bureau of Shipping) Design Assessed lights meet requirements for use on docks and ships.

Lights that meet NSF/ANSI 2 standards are commonly used in food handling and processing areas with splashing liquid.

Top-down protection for your clean rooms—a gasket on these lights seals out contaminants. They’re also covered in an antimicrobial paint and are fully enclosed. What makes them great for clean rooms also makes them great for washdowns and food preparation areas. They’re rated NSF/ANSI 2 for splash zones, so you can use them around splashing liquids from food. They’re sealed against humidity and low-pressure washdowns thanks to their IP65 rating. You can install these IC-rated lights in direct contact with insulation without risking a fire. Their lens disperses light evenly.

Lights with clamping arms will install into any finished ceiling opening, even if you don't have a drop ceiling. They have a prismatic lens that casts a beam that covers a wider area and limits glare better than lights with a smooth lens.

Neutral lights are often used in workspaces. Cool lights highlight white and blue tones for higher visibility than neutral lights.

Prevent contaminants from entering your ISO Class 3 clean room—these lights have an airtight seal. What makes them great for clean rooms also makes these lights ideal for food preparation and other spaces that require frequent washdowns. They’re rated NSF/ANSI 2 for direct contact with food. Rated IP65 and ETL listed for wet locations, they’re sealed against humidity and low-pressure washdowns. They have a cool light appearance that highlights white and blue tones to make your work more visible. A prismatic lens casts a wide beam and limits glare on your equipment.

To install, fasten with No. 14 tapping screws and seal with silicone (both not included).

A gasket seals the enclosure of these backup lights from washdowns. Adjust the heads toward your walkways—they kick on when the power goes out, lighting the path toward exits. Rated UL 924, their battery provides at least 90 minutes of light. A low-voltage disconnect automatically shuts off the battery before it's fully drained, prolonging its overall lifespan. All are dust-tight.

Lights cannot be sold to the listed areas due to energy efficiency regulations.

Lights rated IP65 withstand low-pressure washdowns, like spray from a garden hose. For high-pressure or corrosive washdowns, choose a light rated IP66 or NEMA 4X. Those rated NEMA 13 can withstand light sprays of oil and coolant.

Lights that are rated NSF/ANSI 2 or ETL sanitation marked are approved for use in food processing plants and industrial kitchens.

Choose lights with a battery heater for cold environments such as refrigerated warehouses and outdoor garages.

All have a manual-test switch that lets you verify the battery and heads are working. Lights with automatic battery testing run a self-check once a month. An indicator tells you if they need maintenance.

Style B and D lights are compatible with add-on heads. Run wiring between add-on heads and your backup light to extend lighting into stairwells, exits, and other remote areas. The greater the wattage of the add-on heads—and the more of them you use—the more they’ll reduce your light’s run time. Maximum wattage for add-on heads refers to the total wattage of add-ons you can use without pushing your light’s runtime below 90 minutes.

Maximum distance between lights represents how far you can space out two lights without creating a dark zone.

Brightness is measured in lumens; the higher the lumens, the brighter the bulb. Color rendering index (CRI) is a measurement on a scale of 0-100 of how accurately the light from a bulb represents an object's true colors; the higher the number, the more natural the colors appear. Any CRI value over 80 will show colors true to life. Bulbs with a warm light appearance have yellow tones. Bulbs with a neutral light appearance are often used in workspaces. Bulbs with a cool or daylight appearance have white/blue tones and are good for inspecting. A bulb’s estimated yearly cost is based on 3 hours of usage per day at $0.11 per kWh.

Fluorescent bulbs are energy efficient, but they contain small amounts of mercury (for disposal information, visit www.epa.gov/cfl). Plastic-coated glass bulbs are shatter resistant; the coating retains glass shards if they break.

Bulbs that cannot be sold to the areas listed exceed local regulatory limits on mercury and/or do not meet local efficiency standards.
