LIGHTING FIXTURES

Basic Lighting System
A basic lighting system consists of the source, the means to energize that source, and the means to electrically and optically control the light produced by that source. Fixtures contribute to both forms of control of light from a system.

1. The source is the lamp. Fixtures are designed with the size and characteristics of a specific lamp in mind.
   
2. The second component of a lighting system is the means to energize the source. For example, a fluorescent lamp requires not only electricity but a ballast to perform this function.
   
3. The third component is optical and electrical control. A reflector is one means of optical control. It's a reflective surface that redirects the light striking it. Another means of optical control is the lens which redirects the light passing through it.

Electrical control provides the ability to adjust the amount of light for various situations and tasks. Lighting controls maximize energy savings without sacrificing the quality of the light or the productivity of occupants. Electrical and electronic controls include: Occupancy Sensors, Dimmers, Photocells, as well as the ubiquitous Manual On /Off Switches.
