Two types of recessed luminaires fit attractively into homes. Round recessed downlights are called cans and high-hats. Downlights called troffers are larger square or rectangular downlights that usually house fluorescent lamps or halogen reflector lamps.
- Use a recessed downlight luminaire designed for compact fluorescent lamps, rather than putting a screwbase compact fluorescent lamp in a downlight designed for an incandescent lamp.
- Position recessed downlights near important visual tasks.
- Wall-wash recessed luminaires light a wall evenly. They should be spaced as far from each other as they are from the wall.
- Wall-wash luminaires mounted closer to the wall than 1 foot 6 inches produce harsh, scalloped patterns of light on the wall. Manufacturers provide proper mounting positions on product literature.
- Manufacturers offer a variety of accessories for recessed downlights. Baffles and trim cones that are deep or dark in color reduce a luminaire's efficiency.
- A room may contain many recessed downlights. Home owners can create a variety of scenes if the luminaires are wired in several groups for separate control; wall-wash luminaires should be grouped separately from general room lights. Dimmers installed on incandescent lamps extend the user's ability to set room scenes.
- Grazing light from recessed downlights installed close to walls accentuates taping and sanding irregularities in the same way as light from architectural luminaires.
- Wall-wash luminaires should not be aimed toward doors or windows.

CAUTION - A recessed luminaire installed in an insulated ceiling or roof cavity must be IC rated. IC-rated luminaires are designed so insulation can cover and abut the luminaire. Luminaires manufactured to restrict air leakage through the luminaire are labeled performance tested.
