Disco Fixture is a term used to describe the lighting and sound equipment used in a disco or nightclub. The two most common pieces of equipment associated with this term are the strobe light (6 letters) and the glitterball (11 letters). The strobe light is a flashing light that creates a strobing effect, while the glitterball is a mirrored ball that reflects light around the room. Both of these pieces of equipment are essential for creating the atmosphere of a disco.
