A light fixture, light fitting, or luminaries is an electrical device used to create artificial light and/or illumination, by use of an electric Table lamp. All light fixtures have a fixture body, a light socket to hold the lamp and allow for its replacement—which may also have a switch to operate the fixture, and also require an electrical connection to a power source, often by using electrical connectors (e.g. plugs) with portable fixtures. Light fixtures may also have other features, such as reflectors for directing the light, an aperture (with or without a lens), an outer shell or housing for lamp alignment and protection, and an electrical ballast and/or power supply.

A wide variety of special light fixtures are created for use in the automotive lighting industry, aerospace, marine and medicine.
