Which control can be used to dim fluorescent lighting?

• A. Light Sensors
• B. Occupancy Sensors
• C. Timer Switches
• D. Standard Dimming Switches

Answer: (D)

Dimming fluorescent lighting is about controlling the level of light output by adjusting the power sent to the ballast. A standard dimming switch is designed to provide that range of brightness by delivering a dimming signal to a ballast that can interpret it. When the ballast supports dimming, this switch lets you set lower light levels and smoothly adjust them as needed. The other controls serve different purposes. Light sensors respond to ambient daylight and auto-adjust brightness, but they aren’t used for manual dimming. Occupancy sensors focus on turning lights on or off (and sometimes provide limited dimming in specific setups), not general brightness control. Timer switches simply switch lights on and off at scheduled times.
