Types of Lighting Controls

Lighting Control Systems

Lighting control systems provide the ultimate in lighting energy cost control, streamlined facility maintenance and energy efficiency. They involve communication between the lighting equipment and a central control system that can be adjusted, automated and monitored.

Occupancy Sensors

Occupancy sensors work off of sound or motion control – they automatically dim or switch lights off when an area has not been occupied for a specified amount of time and switch lights back on when motion is detected. This can result in 35-45 percent energy savings.


Dimmers allow the user to adjust the level of lighting from very bright to near dark. Light sources use less energy when dimmed and can automatically save 4-9 percent in electricity usage over a standard toggle switch.


Effective daylighting uses natural light to offset electrical lighting loads. When designed and implemented correctly, daylighting lowers energy consumption and reduces operating and investment costs.

Daylight Dimming

Instead of shutting the lights off when enough daylight triggers the photosensor, daylight dimming allows lighting to be continuously adjusted in proportion to the amount of sunlight available.

Time Scheduling

Scheduling with time clock controls turns lights on and off, sets lighting levels for different times of day and changes the lighting profile for after-hours mode. More sophisticated systems also respond to signals sent from external control devices such as sensors or switches.
