Special lighting is a lighting instrument that used for a very specific purpose. It is rather than as part of a system such as an area light or color wash. Furthermore, it can be used alone, or at a higher level than the other instruments. Moreover, they can be used to highlight specific objects onstage, such as pieces of furniture, or to fill gaps not covered. Besides that, they can also create a very specific effect onstage, such as sunlight through a window, or gobo rotation. In fact, they are generally wired to their own circuits, dimmers, and channels, so it can be controlled independently.
