Ambient lighting, which is considered general lighting, provides the basic lighting for a space or a room. It is the starting point which lighting designers, engineers, and contractors use to start looking at the best way to light a space. Ambient light can come from recessed down lights mounted in the ceiling, ceiling lights mounted to the surface of the ceiling, or table and floor lamps. These types of fixtures characteristically give an even, diffuse light level for the space.
The type of lighting that you want to create for a space or room will depend on the type of light source that is used. You might use soft white incandescent for living rooms and bedrooms to achieve a warm even glow in the space. Fluorescent lights can be used to achieve a higher illumination level in larger areas such as garages and utility rooms.
A good lighting plan combines all types to light an area according to function and style. Any discussion of home lighting must begin with three (Ambient, Task. and Accent) of the five important concepts.
