Which of the following is NOT a component of a typical lighting control system?

A typical lighting control system includes various components that enable users to manage lighting effectively. The correct choice, stating that light fixtures are not considered a component of the lighting control system, makes sense in this context because lighting control systems primarily consist of devices and technologies that manage the operation of the light fixtures rather than the fixtures themselves.

Switches are used to turn lights on or off and may include various types of controls, such as wall switches or remote controls. Sensors, including occupancy sensors and daylight sensors, play a crucial role in making lighting systems more intelligent by automatically adjusting lighting levels based on occupancy or natural light availability. Dimmers are integral to providing flexibility in lighting quality and intensity, allowing users to adjust the brightness to meet varying needs and preferences.

While light fixtures are essential for producing light, they do not fall under the operational control mechanisms within a lighting control system; instead, they serve as the output component that responds to the controls provided by switches, sensors, and dimmers.
