These lights produce a wide beam of uniform light to fill large, open areas with ceilings up to 18-ft. high.

Hazardous Location Ceiling Lights

Suspend or mount with fasteners to the ceiling.

High-Temperature Hazardous
Location Ceiling Lights

Built for hot, hazardous areas such as steel mills and refineries, these lights work in temperatures up to 212° F. Rated NEC Classes I and II, they’re safe to use where there are ignitable concentrations of flammable or combustible gases, vapors, liquids, and dust.

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.

Tubular Machine Lights

These classic-style machine lights have a reflector to distribute light more evenly than strip machine lights.

Color-Changing Tubular Machine Lights

Just like traditional tubular lights that illuminate your machine with a bright white light, these lights can also be programmed to switch over to a red or green light for communicating machine status.

Easy-Retrofit Machine Lights

Update conventional fluorescent tubular lights with newer LED technology. These lights match the diameter of most older lights and fit existing brackets without the need to drill new mounting holes.
