What Is a Recessed Light?
A recessed light is a light fixture that sits within an opening in a ceiling or wall. Its visible trim surrounds a light source that shines into the room. The fixture gives the surface a low-profile look and can provide focused or general light.

How Recessed Light Works

A recessed light receives power through wiring connected to a lighting circuit. A switch controls the flow of power to the light source. Some fixtures use a replaceable bulb, while others have an LED built into the fixture. Related service: Recessed Lighting Installation.

The trim affects the appearance of the opening and the direction of the light. An adjustable trim lets you aim light toward a wall or a work area. A fixed trim keeps the light aimed in a set direction.
Some fixtures use a housing that fits inside the ceiling. Others have a slim body and a separate connection box. The ceiling space and the fixture design affect which style fits your room.

From the Electrician Pittsburgh team
When we plan recessed lighting installation, we look at the ceiling space and the room's use. We also check the fixture's connection method before choosing where the wiring will run. That helps us plan around framing and other material above the ceiling.
