Define the term "spotlight."

The term "spotlight" specifically refers to a focused beam of light that is used to illuminate a particular subject, such as an actor or a specific area on stage. This type of lighting tool allows for precision in highlighting moments or performances during a production, creating emphasis and drawing the audience's attention to key elements on stage. Spotlights are often adjustable, enabling the operator to change the angle and size of the beam to suit their lighting needs. This characteristic makes spotlights an essential component in theatrical lighting design, as they help to create mood and focus within a scene, enhancing the overall visual storytelling of the performance.

In contrast to this, a broad lighting tool implies a less focused approach, which would not serve the purpose of spotlighting individual performers or moments effectively. Similarly, stage props and costume equipment relate more to physical elements of the production rather than specific lighting techniques.
