  2. 0-10 V lighting control - Wikipedia

    en.wikipedia.org/wiki/0-10_V_lighting_control

    Dimming fluorescent ballasts and dimming LED drivers often use 0–10 V control signals to control dimming functions. In many cases, the dimming range of the power supply or ballast is limited. If the light output can only be dimmed from 100% down to 10%, there must be a switch or relay available to kill power to the system and turn the light ...
