Ceiling- and Wall-Mounted Luminaires

  • The RE730, RE827, and RE830 fluorescent lamps that work in architectural and recessed luminaires can be used in ceiling- and wall-mounted luminaires.
Bedroom with a ceiling-mounted luminaire containing linear fluorescent lamps.
  • Luminaires containing linear, long twin-tube, or circline fluorescent lamps are ideal for kitchens, playrooms, home offices, and utility rooms.
  • Screwbase capsule or screwbase globe compact fluorescent lamps fit many simple ceiling-mounted luminaires and porcelain sockets. For example, a capsule compact fluorescent lamp in a porcelain socket is a good choice for a basement or utility room if the light is left on for long periods of time.

Hallway with wall sconces designed for compact fluorescent lamps and night light.
  • Select wall sconces that are designed solely for compact fluorescent lamps for hallways, bedrooms, and living rooms, and in rooms with low ceilings.
  • In bathrooms, luminaires positioned vertically at the sides of the mirror and above light-colored counters provide the best visibility to the underside of the chin. Linear or long twin-tube fluorescent lamps work especially well in the bathroom in separate luminaires or built into vanity mirrors or medicine cabinets.
  • Compact fluorescent globe lamps substitute for the incandescent Hollywood lights popular with home owners. When a home owner insists on vanity lights above the mirror, the luminaires should be 6 feet 6 inches above the floor.

  • Incandescent track lighting should be used only where flexibility or accent lighting is important. If the track heads do not have a built-in reflector, use halogen reflector lamps.
  • Position track heads so lamps are not visible from usual seated or standing positions.
  • Wall-mounted luminaires less than 6 feet 8 inches from the floor should not protrude more than 4 inches from the wall.
  • Installing junction boxes at least 5 feet 9 inches above the floor allows wall sconces to be positioned high enough so that people don't bump into them.

When you purchase a luminaire, look for the "ENERGY STAR" label.
