Which type of outlet is intended for the direct connection of a lampholder or luminaire?

A lighting outlet is specifically designed for the direct connection of a lampholder or luminaire, making it the appropriate choice for this question. The definition of a lighting outlet in the National Electrical Code (NEC) emphasizes its purpose of facilitating the installation of light fixtures directly. This type of outlet ensures that the fixture can be securely and safely connected to the electrical system, providing the necessary support and wiring for effective operation.

In contrast, power outlets are typically designed for general electrical devices and may not be suited for direct light fixture connections. Dedicated outlets are used for specific appliances or equipment, providing exclusive circuitry for their operation. General purpose outlets are versatile but again not specifically designated for lighting fixtures. Each of these other outlet types serves a different purpose, which helps clarify why the lighting outlet is the best choice for connecting lampholders and luminaires directly.
