About Brightness and Light Appearance

Find the right lumen level to brighten your space. Then, compare the way warm, neutral, and cool lighting affect the appearance of everyday objects.

Ceiling and Wall Lights

Linear Bay Lights

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.

Round Bay Lights

Brighten large, open areas, such as warehouses and manufacturing spaces. IP rated and UL listed for wet locations, these lights are sealed against washdowns.

High-Temperature Linear Bay Lights

Rated for over a decade of use well above 100° F, these linear bay lights long outlast standard facility lights in high heat.

Linear Ceiling Lights

Link these lights together to create different shapes with a sleek look.

Hazardous Location Linear Bay Lights

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.

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.

Retrofit Hazardous Location Round Bay Lights

Upgrade your existing hazardous location bay lights to energy-efficient LEDs.

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 other liquids.

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.

Explosion-Proof Floodlights

Light up offshore rigs, coal mines, and other outdoor areas where gas, vapor, or dust could ignite. These lights have an enclosure that contains sparks and explosions, so they won’t react with nearby hazards.

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.
