Which phrase describes turning on theatre or film set lights?

• A. Lights On
• B. Light Striking
• C. Light Saving
• D. Lighting Up

Answer: (B)

The main idea here is the specific terminology used by lighting crews to indicate bringing illumination onto a set. In traditional theatre language, to strike a light means to ignite or bring a light into operation. Extending that idea, the act of turning on and activating the lights on a film or theatre set is described as lighting or striking the lights. So the phrase describing the moment you bring the lights to life is light striking, which captures the action of initiating illumination rather than simply stating that the lights are already on or that you are saving energy. While others might say lights on or lighting up in casual speech, light striking fits the historical and technical phrasing used on sets about starting the lighting for a scene.
