One of the main goals of interior design is to augment the available space in each room. Professional interior designers often prefer recessed lighting fixtures, as these are implanted into the ceiling or floor and eliminate the need for visible switches, dangling cords, lampshades, bulbs or anything that might interrupt the overall view of a room. There are recessed lighting fixtures with all needed functions, sleek designs, elegant styling and modern features. Different types of recessed lighting fixtures are available in the market, most of which provide different varieties of lighting options for users.
Recessed lighting planning deals with the proper arrangement of a complete set of recessed lighting fixtures and related parts. Interior designers use various combinations of fixtures to produce light that may be focused and bright, diffused and soothing, or a happy comprise lying between the extremes. The first step in recessed lighting planning is the selection of the housing and covering that determines the pattern of light dispersed by the fixture. The next step in recessed lighting planning deals with the selection of the type of bulbs, which may be fluorescent, halogen, or incandescent. Fluorescent lights help to reduce electricity bills; halogen bulbs can be used in low 
voltage varieties and incandescent bulbs provide a soothing glow whose brightness can be varied with the help of a dimmer switch.
Recessed lighting planning deals with the proper arrangement of reflectors for deflecting light into corners or onto work desks. Recessed lighting planning also deals with the selection of diffusers, which are made from plastic or glass and are used for altering the light emitted by a bulb. Users can select different types of diffusers, depending on the lighting requirements of a room. Another important thing to consider during recessed lighting planning is the selection of the appropriate type of trims, which are decorative elements and the most visible part of a recessed lighting fixture, lying flat against the ceiling. Trims are usually made from white plastic, but other colors can be chosen to either blends with or contrast with the color of the ceiling.
