Lamps, All Types Information on GlobalSpec

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.

Fluorescent lamps, halogen lamps, and heat lamps are three common types of lamps. Fluorescent lamps are high-efficiency lamps that use the electrical discharge of low-pressure mercury vapor to produce ultraviolet (UV) energy. The UV light is transformed into visible light. These common lamps than can be found in offices, homes, stores and street lights. Halogen lamps are high-pressure incandescent lamps that contain halogen gases such as iodine or bromine. These gases allow the filaments in halogen lamps to be operated at higher temperatures and efficacies. Heat lamps are also known as infrared emitters, infrared bulbs, infrared tubes, or infrared lamps. These lamps differ from illuminating lamps because of their low filament temperature, which results in less light and increased infrared (IR) radiation.

Incandescent lamps, LED lamps, and many other types of lamps are also available. Incandescent lamps generate light by passing electric currents through a thin filament wire until the wire is extremely hot. Light emitting diode (LED) lamps are arrays that contain traditional lamp ballasts. Other types of lamps include projection lamps, spectral lamps, and stage lamps. Projection lamps use a built-in reflector to concentrate light in a particular direction. These types of lamps are used in a variety of applications. Examples include slide projection, microfilm, overhead projectors, movies, medial and scientific instruments, and airport runways. Spectral lamps are lamps that radiate line spectra of various gases and metal vapors with high brightness and spectral purity. Stage lamps are typically used for stage, studio, or television lighting applications.

Selecting lamps requires an analysis of specifications and features. Performance specifications include lamp power (wattage), bulb-burning lifespan, overall length of the lamp, color temperature of emitted light, and the average lamp output. Some lamps are available with additional features such as compact design, reflectors, shatterproof coating, twin tube filaments, and water-cooling. Additional features may be available through certain manufactures.

Products & Services Related to Lamps, All Types

Fluorescent Lamps

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

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.

Heat Lamps

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.

High Intensity Discharge Lamps

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.

Incandescent Lamps

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

Projection Lamps

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.

Stage Lamps

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.
