Collection: Recessed Lighting Housings & Cans

A recessed lighting housing (also called a "can" or "pot") is the metal cylinder installed inside the ceiling cavity. It contains the electrical connections and provides the structural mount for the visible trim and light source. The housing is hidden above the drywall and is never seen once installation is complete.

New construction housings are installed before drywall, mounting to ceiling joists via hanger bars. Remodel housings are installed after drywall is in place — the fixture passes through the cutout hole and is secured by spring clips that grip the drywall from inside. If your ceiling is already finished, you need a remodel housing.

"IC" stands for Insulation Contact. An IC-rated housing is tested and approved to be in direct contact with ceiling insulation without creating a fire hazard. Most modern building codes require IC-rated housings in insulated ceilings. Non-IC housings must maintain a minimum 3-inch clearance from all insulation.

No. Canless recessed lights (also called wafer lights) are self-contained fixtures that clip directly into the drywall cutout with no housing required. They are ideal for remodels with shallow ceiling cavities. See our canless recessed lighting collection for housing-free options.

Not always. Trims and modules are generally designed to fit specific housing brands and sizes. Always verify that the trim or LED module you select is rated to fit your housing's aperture size (e.g., 4-inch or 6-inch) and brand family. When in doubt, purchasing a complete housing-and-trim kit from the same manufacturer guarantees compatibility.

An airtight housing is sealed to prevent conditioned air from escaping into the ceiling cavity, improving your home's energy efficiency. Many building codes and energy programs (such as ENERGY STAR) require airtight housings in conditioned spaces. Look for housings labeled "AT" or "IC/AT" for both insulation contact and airtight compliance.

The housing size determines the aperture of the finished light. 4-inch housings are the modern residential standard for task and accent lighting. 6-inch housings are the traditional standard for general ambient lighting in larger rooms. Choose based on the trim and LED module you plan to use, as they must match the housing size.

Technically yes, but it is not recommended. New construction housings mount to joists before drywall, providing a more secure and precisely positioned installation. Remodel housings rely on drywall clips, which are less rigid. For new builds, always use new construction housings for the best result.

No. Recessed lighting housings include an integrated junction box as part of their construction. All electrical connections are made inside the housing's wiring compartment, which is code-compliant and eliminates the need for a separate junction box.

"AT" stands for Airtight. An AT/IC-rated housing meets both the insulation contact (IC) and airtight (AT) standards, making it the most versatile and code-compliant choice for insulated ceilings in conditioned living spaces. This is the recommended specification for most residential new construction projects.
