A lighting plot is a technical document that outlines the placement and details of the lighting equipment for a live performance or event. It includes information such as the location of lighting instruments, their function, and how they are used to enhance the overall production. This includes details like the timing and intensity changes of lights, which help to create different moods and atmospheres throughout the performance.

While elements such as the set's layout and visual elements may be referenced in a lighting plot, they are not typically included as the main focus of the document. Costume designs and sound effects are separate components of a production and are not typically part of a lighting plot.
