Ceiling Strip Lights

Also known as channel lights, the ends of these fixtures can be wired together to create long rows of lights to illuminate indoor workspaces such as offices and workshops. Rated for use in damp locations, these lights withstand humidity and moisture. They have built-in LEDs, which last longer, are more efficient, and generate less heat than other light technologies. They emit a neutral white light often found in workspaces. Lights can be hardwired to operate on any of the voltages listed.
Add suspension hardware (sold separately) to hang lights from the ceiling. Includes two wire rope slings with hooks and two wire rope clamps. No tools required—adjust the length and tighten clamps to secure.

Retrofit Ceiling Strip Lights

Fit traditional fluorescent ceiling strip lights with LED lights, which use less electricity. DLC (DesignLight Consortium) listed, these lights have been tested to confirm their energy efficiency. They mount to standard 4 1/4" to 5 1/4"-wide housings with the included screws and safety cables. Hardwire them into your system—they automatically adjust to match the incoming power. Remove the old bulbs and their wiring before installing these lights.
The lens resists scratching and won’t yellow over time, since it’s made of acrylic. It’s also frosted to disperse light and reduce glare.
Lights with a neutral light appearance look less clinical than those with a cool light appearance. They’re common in offices, showrooms, retail stores, and other workspaces.
Lights with a cool light appearance highlight white and blue tones. They’re also brighter than those with a neutral light appearance. Use them in environments that require high visibility, such as warehouses, workshops, and inspection areas.

Retrofit Recessed Ceiling Lights


Upgrade your fluorescent recessed lighting to energy-efficient LEDs without removing fixtures and exposing insulation. No need for a permit—these lights don't require opening the space above the ceiling. They connect to standard housings with the included springs and cables. Just remove the old lens, bulbs, drivers, and their wiring before installation. DLC (DesignLight Consortium) listed, these lights have been tested to confirm their energy efficiency. They’re also ETL listed for use in damp locations.
Adjust the light appearance and brightness to match your existing lighting. The frosted lens disperses light evenly to prevent glare on equipment.
