Lighting controls represent a major part of a high quality energy efficient lighting system that integrates daylight and electric light sources in order to provide a comfortable and visually interesting environment for the occupants of a space. Electric lighting controls are appropriate for a wide variety of spaces, from large open offices, to conference rooms and classrooms. Controls can be incorporated with daylight to provide flexibility, energy savings, and ecological benefits.

When electric lighting controls are used properly, energy will be saved and the life of lamps and ballasts can be extended . Lighting controls will help reduce energy by:

• Reducing the amount of power used during the peak demand period
   by automatically dimming lights or turning them off when they are
   not needed.

• Reducing the number of hours per year that the lights are on.

• Reducing internal heat gains by cutting down lighting use (allowing for
   reduced HVAC system size and a reduction in a building's cooling
   needs).

• Allowing occupants to use controls to lower light levels and save
   energy.
