Pipe/Surface-Mount Flashing Lights
Lights meet NEMA 4X for protection from corrosion and washdowns.
LED bulbs last longer than halogen bulbs and provide years of maintenance-free operation.
Light intensity is measured in candlepower (cp), which indicates how bright a light appears at a distance. Common examples include a car’s taillights (50 cp), traffic signals (600 cp), headlights (15,000 cp), high beams (50,000 cp), and police car searchlights (150,000 cp).
Pipe-Mount Revolving Lights
Zinc lights meet NEMA 4X for protection from corrosion and washdowns. Use the surface-mount bracket (sold separately) to attach lights to a wall or other surface.
Light intensity is measured in candlepower (cp), which indicates how bright a light appears at a distance. Common examples include a car’s taillights (50 cp), traffic signals (600 cp), headlights (15,000 cp), high beams (50,000 cp), and police car searchlights (150,000 cp).

Stem-Mounting Hardware for Ceiling Lights



Finish your ceiling fixtures with a more polished look than chain or wire rope. All have sockets that swivel up to 8° to mount on sloped ceilings. Use them to hide wiring from an outlet box to your fixture for a seamless appearance.
Mounts don’t include a stem. They’re intended for bay lights with a 1/2 or 3/4 NPSM top connection. Add your own threaded conduit as the stem.
Mounts with 18" stem are intended for strip lights or fixtures with 3/8 trade size conduit knockouts on top. Remove the knockout and attach the stem with the included washer and nut.

Sockets for Bayonet Base Light Bulbs


Add lighting to machinery that’s prone to vibration—these sockets lock bayonet-base bulbs in place to resist bumps and movements. They make replacing bulbs easy because you don’t have to thread the bulbs in like screw-in sockets.
Bracket mount sockets require No. 6 screws (not included) for installation.
Pipe mount sockets are installed by drilling a 3/8" hole in your panel and securing the pipe nipple with a panel nut (sold separately).
