Recessed Lights more colloquially known as pot lights or can lights, because of their shape, are lighting fixtures that are installed into hollow openings in ceilings or walls. When installed they look like a glowing hole in your ceiling concentrating the light in a downward direction. An interior housing rests on the hole, covering the electrical elements. An exterior trim covers the rough cut hole, attached to the housing. The housing is intended to protect the lighting fixture from fire hazards and flammable materials.
Summarized there are three parts of a recessed lighting fixture: housing, trim and bulb. The trim is the visible portion of the light. It is the insert that is seen when looking up into the fixture, and also includes the thin lining around the edge of the light. The housing is the fixture itself that is installed inside the ceiling and contains the lamp holder.
Recessed lighting has an uncluttered look that provides light within the home without taking up headroom or ceiling space. Recessed lights are often used to highlight wall fixtures or to provide focused overhead lighting for reading or working. Recessed lighting offers the advantages of being a hidden light source and moreover it is energy efficiency.
Additionally, in retail and consumer settings, LED down lights do not emit damaging ultraviolet or infra-red light, so fabrics and artwork can be illuminated without colour deterioration. Also, high quality LEDs produce better light that shows colour more effectively than fluorescents.
LED recessed Lights are designed to last about 50 times longer, which means less maintenance and less time spent on replacing burned-out bulbs that are often very hard to get at. The lifespan of an LED is simply unmatched by other types of lighting. Your typical LED light will last approximately eleven years based on twelve hours of use per day.
LED recessed lighting uses solid-state technology, which allows effective dimming in many applications and eliminates flickering. Use different dimmers to create zones of adjustable lighting throughout a room or home.
