Lighting fixtures produce artificial light in industrial areas or workspaces. They are electrical devices that hold one or more lamps and provide illumination. Most are designed for use with fluorescent, halogen, incandescent, light-emitting diode (LED), mercury, metal halide, sodium, or xenon lamps.

Types

Lighting fixtures are available in many different types:

• Desk lamps and table lamps are used for task lighting.
• Enclosure lights are used to provide illumination within enclosures.
• Flood lights are used to light a location or object to a luminance that is considerably greater than its surroundings.
• Floor lamps or sticks are standing lamps used for general-purpose lighting.
• Pendants or suspended luminaries hang from the ceiling, or from a cable or track system, by supports. Recessed lights include down lights and fluorescent troffers.
• Track lights mount on the ceiling and consist of metal rods and movable light fixtures that snap into place. 

Specifications

Light fixture voltage (V) and light fixture wattage (W) are standard performance specifications for most products. High intensity discharge (HID) lamps such as metal halide lamps may carry additional specifications such as spectral distribution, rated average life, lamp power, initial lumens, color rendering index, and color temperature. Halogen light fixtures range from 10 W to 1,000 W and LED light fixtures come in a variety of shapes and sizes.

Applications

Some lighting fixtures are designed for aerospace, automotive, industrial, marine, or outdoor applications. Others are used in residential, security, theatrical, or photography applications. Lighting fixtures for scientific, medical, or dental applications are also available.

Features

Common features for lighting fixtures include ballasts, bulbs, battery power, solar power, dimmers, fans, light detection, and motion detection.
