Lighting and fixtures are used for illumination purposes or to provide a source of light for a specific application. This category includes halogen, incandescent, fluorescent, and lighting fixtures.
Ballasts are electrical devices that condition the line voltage (amplitude, amperage and waveform) to operate fluorescent and HID lamps. Basically they serve two functions: to provide the starting kick, and to limit the current to the proper value for a particular lamp.
Fluorescent lamps are high-efficiency lamps that use electrical discharge through low-pressure mercury vapor to produce ultraviolet (UV) energy, which is then transformed into visible light.
Halogen lamps are high pressure incandescent lamps containing halogen gases such as iodine or bromine, which allow the filaments to be operated at higher temperatures and higher efficacies.
High intensity discharge lamps (HID) contain compact arc tubes, which enclose various gases and metal salts, operating at relatively high pressures and temperatures. HID lamps are often used as UV light sources.
Illuminators are used to provide adequate contrast for imaging. Illuminators include backlights, LED illuminators, and fiber optic illuminators.
Incandescent lamps generate light by passing an electric current through a thin filament wire (usually of tungsten) until the wire is extremely hot.
Heat lamps are also known as infrared emitters, infrared bulbs, infrared tubes, or infrared lamps. Heat lamps differ from illuminating lamps in their low filament temperature, resulting in much less light and more infrared radiation.
Lampholders are mechanical devices that support lamps and connect them to electrical circuits. They hold light bulbs and make electrical contact to provide a bulb with power.
Lamps are light sources that emit incoherent light for illumination. There are many different types of products. Examples include fluorescent lamps, halogen lamps, heat lamps, incandescent lamps, LED lamps, projection lamps, spectral lamps, and stage lamps. Specialized and proprietary lamps are also available.
LED lamps are light emitting diode arrays with traditional lamp ballasts.
Lighting fixtures produce artificial light in industrial areas or workspaces.
Projection lamps use a built-in reflector to concentrate light in a particular direction. They are used in applications such as slide projection, microfilm, overhead projection, movies, medical / scientific instruments, airport runways, and others.
Searchlights or spotlights are powerful light sources that use a parabolic reflector to project a beam of light in order to identify aircraft or draw attention to an area.
Spectral lamps radiate line spectra of various gases and metal vapors with high brightness and spectral purity.
Stage lamps are used for stage, studio, or television lighting. They are often made of quartz instead of glass to provide higher pressure ratings, higher melting temperatures, and more energy-efficient designs.
Street lights are elevated light sources that illuminate dark public areas, most commonly roads, walkways, and parking lots. They are also referred to as street lamps.
