Lenses for Ceiling Lights

Lenses disperse light to reduce glare, while protecting bulbs from damage.

Wraparound-Lens Ceiling Lights

A wraparound lens disperses light from the sides as well as the bottom to produce ambient lighting.

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.

Recessed Ceiling Lights

Also known as troffers, these lights fit most standard drop-ceiling grids.

Recessed Can Lights

These lights fit into ceiling cutouts.

Plug-In Ceiling Lights

No need for wiring—these lights plug-in with a two-prong plug. Also known as shop lights.

Battery-Operated Motion-Sensing Ceiling Lights

Mount these fixtures where you need light but don't have an electrical connection. They automatically turn on when movement is detected and off when an area is unoccupied.

Wall Lights

These lights mount to the wall so they're often used in enclosed spaces such as stairwells, hallways, and storage rooms.

Hazardous Location Ceiling Lights

Suspend or mount with fasteners to the ceiling.

Wraparound-Lens Wet-Location Ceiling Lights

A wraparound lens disperses light from the sides as well as the bottom to produce ambient lighting.

Also known as jelly jar lights. These fixtures have a guard that protects the lens from breaking.

Wet-Location Recessed Ceiling Lights

Mount these lights flush with ceilings in wet locations—all are sealed to keep out humidity and dripping, splashing, and falling liquids. Unlike recessed can lights, which require a separate housing, these fit directly into a cutout in your ceiling and are held in place by springs.

Washdown Ceiling Lights

A sealed lens keeps moisture out to protect these lights against washdowns.

Polarized Light Filters

Reduce the glare from reflective surfaces.

Ultraviolet Light Filters

Block the transmission of ultraviolet light.

Colored Light Filters

Change the color of a room; filters allow only the same color lightwave to pass through.

Large-Area Floodlights

Illuminate outdoor areas and objects such as parking lots, flag poles, and billboards.

Security Lights

Also known as wall packs, these lights mount to exterior walls and ceilings.

Solar-Powered Motion-Sensing Security Lights

Powered by the sun, these security lights function in areas that don’t have access to electricity. They’re often used to shine light on parking lots, landscaping, signs, entryways, and other outdoor spaces.

Solar-Rechargeable Portable Lights

Use sun energy to bring light to remote areas and storage spaces without electrical wiring. These lights come with a solar panel to recharge their battery.

Plug-In Portable Lights

Hang these lights where you need them on the job site.

Washdown Portable Lights

With a NEMA 4X rating, these lights resist degradation when exposed to corrosive liquids, withstand liquids sprayed during washdowns, and are dust tight.

Lanterns

Provide 360° of lighting.

Workstation Strip Lights

Suspend these lights overhead or mount them above your workspace.

Wet-Location Emergency Backup Lights

These lights are sealed to protect against humidity, moisture, and dripping and splashing liquids.

Emergency Backup Lights

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