Recessed downlight housings without a light source include the can, mounting hardware, and electrical connections but not the trim module that emits light. They allow standardizing on can size and installation type while leaving flexibility to select trim modules to suit lighting needs, match color schemes, and make updates as styles and technology evolve. These LED downlight housings typically last longer than other lighting technologies and use less energy to reduce operating costs. They recess into ceilings and set the edge of the housing flush with the surface to blend into ceilings for a clean look that doesn't draw attention to the fixture. Typical applications include multifamily housing, hospitality, retail, office, and healthcare settings.
