Lighting control consoles:

(also called lighting boards or lighting desks) are electronic devices used in theatrical lighting design to control multiple lights at once. They are used throughout the entertainment industry and are normally placed at the Front of House position or in a control booth. 

All lighting control consoles can control dimmers which, in turn, control the intensity of the lights. Many modern consoles can also control automated lighting, fog machines and hazers, and other special effects devices.
