What term is used for turning on theatre or film set lights?

The term "Light Striking" refers specifically to the action of turning on or activating the lighting fixtures on a theater or film set. This process is essential in setting the mood, highlighting scenes, and ensuring visibility for performances or recordings.

When lights are "struck," it usually indicates that they are being energized for use, whether that's testing their functionality or preparing them for a shoot or show. This moment is crucial because it helps the crew assess the lighting levels and make necessary adjustments to achieve the desired look and feel for the production.

The other terms might relate to lighting in some context, but they do not accurately represent the specific act of turning on the lights. Thus, "Light Striking" is the precise terminology used within the industry for this important step in the production process.
