Lighting controls help to conserve energy in a variety of ways. A few examples of lighting control options are dimmers, radio RA systems, photocells, and time clocks.
Dimmers conserve energy by creating the option of adjusting the lighting levels when the highest level of lighting is not needed. Radio RA systems are used to operate lighting with lower light levels while providing complete control to the user. Photocells and time clocks are also a lighting control option that helps conserve energy. Photocells and time clocks are primarily used on outside lights as a control mechanism that lights an area only when needed therefore creating a more efficient outdoor lighting system overall.
