Lighting Fixtures and Lamps

Lighting fixtures and lamps 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.

BallastsBallasts 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 LampsFluorescent 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 LampsHalogen 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.

Heat LampsHeat 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.

High Intensity Discharge LampsHigh 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.

Incandescent LampsIncandescent lamps generate light by passing an electric current through a thin filament wire (usually of tungsten) until the wire is extremely hot.

LampsLamps 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 LampsLED lamps are light emitting diode arrays with traditional lamp ballasts.

Lighting FixturesLighting fixtures produce artificial light in industrial areas or workspaces.

Projection LampsProjection 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.

Spectral LampsSpectral lamps radiate line spectra of various gases and metal vapors with high brightness and spectral purity.

Stage LampsStage 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.
