Also known as troffers, these lights fit most standard drop-ceiling grids, so they’re often used in indoor spaces such as offices and storage rooms. They can be hardwired to operate on any of the voltages listed. Solid lens are frosted and smooth or prismatic to disperse light evenly. With built-in LEDs, these lights last longer, are more efficient, and generate less heat than fluorescent lights. They emit a neutral white light often found in workspaces.

Create recessed can lights by pairing a housing with a light. These lights fit into ceiling cutouts to provide directed, ambient lighting so they’re often used in indoor spaces such as offices and lobbies, or for decorative lighting. Rated for use in damp locations, these lights withstand humidity and moisture.

Housings for unfinished ceilings are mounted between support beams. Expand the hanger bars to fit spaces up to 25 1/4" long. Slide the housing along the hanger bars to adjust the location of the light.

Housings for finished ceilings don’t require access to support beams. They are held in place by clips.

Lights have built-in LEDs, which last longer, are more efficient, and generate less heat than other technologies. Clips on the sides hold the light in a housing.

Baffle-reflector lights minimize glare and soften the light. Smooth-reflector lights focus light down.

Install screw-in base lights using the screw-in base converter.

Lights with a hardwire connection have three switches for adjusting their brightness and light appearance.

Warm light highlights yellow tones similarly to incandescent bulbs. Neutral light is often used in offices and retail stores. Cool light is best for performing detailed tasks and inspections.
