Temporary Light Bulb Sockets

Also known as pigtail holders. Temporarily wire these sockets to provide light during construction. They have a rubber lip that molds around bulbs to form a water-resistant seal.

LED Retrofit Strip Lights

Fit traditional fluorescent ceiling strip lights with these LED lights, which use energy more efficiently, last longer, and produce less heat. They mount to standard 4 1/4" to 5 1/4"-wide housings with the included screws and safety cables. Remove the old bulbs and their wiring before installing these lights.

Brightness is measured in lumens; the higher the lumens, the brighter the bulb.

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, and they’re brighter than those with a neutral light appearance. Use them in environments that require high visibility, such as warehouses, workshops, and inspection areas.

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.
