Updated 2.7.2019 – Recessed lighting is a type of fixture that can be built into walls, ceilings, or floors of a structure. Understanding what each part does and the terminology used to describe the many types of recessed lighting will help you choose the right fixture for any room. Recessed housing, more commonly known as a can, consists of the fixture’s socket, electrical hardware, a protective shell, and brackets or clamps for secure mounting.
If you’re placing lights in an existing structure, remodel housings slip into a small opening and have adjustable arms that provide a secure fit.
New construction fixtures attach directly to structural supports, making them an excellent choice for installation in unfinished walls or ceilings. Pro Tip: It’s a good idea to measure each fixture location and check it for obstructions such as pipes or air ducts before you finalize your lighting plan.
Insulated walls typically form a barrier between the climate-controlled sections of your home and areas exposed to outdoor temperatures. Using airtight IC housings in these locations can reduce drafts and save money on your energy bill. Adjustable trims have a swivel joint that lets you point the light they produce in a particular direction.
Baffle trims have grooved reflectors that diffuse ambient light making them ideal for bedrooms or living rooms.
Decorative trims have shades that extend beyond the installation surface, adding color and texture to a room. Wall wash trims have a solid cover over half their face that directs light to the side.
If you have existing recessed lighting, retrofit modules let you use energy-efficient LED bulbs in incandescent fixtures. Dimmable fixtures let you create a particular mood in the bedroom or dim the lights when watching a movie in the family room.
