In electrical terminology, a luminaire is best defined as what?

• A. Switch
• B. Receptacle
• C. Light fixture
• D. Ballast

Answer: (C)

The main concept here is what a luminaire represents in electrical terms: the complete lighting unit that emits light. A luminaire is the assembly that houses the lamp and carries its wiring and other components needed to produce illumination. It isn’t just a switch, which only controls power; it isn’t a receptacle, which is an outlet; and while some luminaires include a ballast inside to regulate current for certain lamp types, the ballast itself is only a component, not the whole lighting unit. So the best answer is the light fixture.
