Patent Number: 4158132 
Title: Lighting Control System with Cue Level Information 
Abstract: A stored-cue lighting-control system for controlling the illumination of a selected space, such as a stage. The system includes a photodetector for following the level of illumination in the space. During storing of cue data associated with a particular cue, related data, regarding the level of illumination intended to be produced by the cue, is also stored. During functioning of the system to place different successive cues in the space, the stored illumination level data is compared with current real-time data reflecting the actual illumination level then being produced in the space. An indicator signals any difference noted as a result of this comparison.
