What is a lighting outlet?

A lighting outlet is defined as a box that contains branch circuit conductors specifically connected to a luminaire, which is a device that provides illumination. The purpose of a lighting outlet is to supply power to a light fixture or lamp, facilitating its connection to the electrical supply. This definition highlights the functionality of the outlet in the overall electrical system, where it serves as a crucial point for connecting lighting fixtures directly to the circuit.

The other options, while related to lighting, do not accurately describe what a lighting outlet is. A device for controlling lamps suggests an element of switching or dimming capabilities but does not represent the physical connection point for power. Similarly, a power supply port for lighting implies a more generic connection not specifically tied to a designated outlet. Lastly, a connection point for outdoor lighting suggests a specific application without encompassing the full definition of a lighting outlet as used in electrical terminology.
