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. Rated for use in damp locations, these lights withstand humidity and moisture.
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 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.

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. 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.
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).
