Recessed lighting

Recessed lighting
Recessed lighting can provide dramatic, low-profile illumination for every room of the house. These fixtures are embedded into the ceiling, so there are no dangling cords, switches, lampshades, or bulbs to interrupt your view. Different varieties of recessed lighting can provide ambient, accent, task, and flood lighting depending on their bulbs, housing, and trim.


Another part of recessed lighting is the trim. As the most visible piece of material, this ring lays flat against the ceiling. A decorative element, trim can be white plastic to blend in with the ceiling, or tinted for a splash of color. Trims may also be incorporated into baffles, slight extensions that direct the beam of light into one area, such as toward a sink or desk.


Universal recessed lighting fixture is unique because it consists of the same complete unit, ready to install in any ceiling construction (retrofit, new construction), with the housing, trim and junction box included whether it is line voltage or low voltage recessed light.


Whether you are buying a simple desk lamp, accessory lighting for the living room or new lighting for an addition to the home, the first decision to make is how much light is required.
The lighting you select will depend on the job that needs to be done. Consider these basic guidelines:
1. General lighting provides moderate light throughout a room. Using several fixtures creates uniform lighting and minimizes glare and contrasts.
2. Task lighting supports activities such as reading and cooking. These activities may require more focused lamps, in addition to general lighting.
3. Protective and safety lighting helps prevent accidents in such areas as stairwells, and it discourages prowlers.
4. Decorative lighting highlights such room features as drapes, a fireplace or a piece of art.

Recessed Downlight Fixtures


Recessed downlight fixtures have a cylindrical, can-like shape and are recessed into the ceiling. The bulb is generally screwed in at the top of the fixture. Reflector lamps, also called “R” lamps (either incandescent, halogen or compact fluorescent) are usually used in these downlight fixtures.

If an R lamp (see illustration) is being used, consider an ER or BR lamp, as their shape allows better focus of the beam and the use of a lower wattage light than a standard R lamp.
Some fixtures have reflectors designed for a specific lamp shape, in which case a replacement lamp of another shape or length may not distribute the light as efficiently. Some compact fluorescent spotlights and floodlights come with their own reflector, increasing the amount of light that leaves the fixture.

Recessed fixtures may cause heat loss or condensation on cool surfaces due to airflow through the ceiling opening around the fixture and into the attic or roof space. One way to avoid this is to use surface-mounted track lighting instead of recessed fixtures. If recessed lighting must be used, select airtight fixtures that are rated for insulation contact to avoid a fire hazard.
