Lighting fixtures and lamp sockets produce artificial light in industrial areas or workspaces, and mechanically hold and electrically connect lamp bulbs to wiring

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

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

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.

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.

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

Commercial lighting is designed to illuminate commercial and industrial environments.

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

Lighting component parts and accessories include lamp tubes, phosphors, filaments, bases, and other lamp parts.

Polarimeters determine the amount of polarization of light

Industrial dyes are colorants consisting of single molecules that are able to absorb certain parts of the spectrum of visible light and reflect others. Dyes are soluble in the material in which they are dispersed

Colorants, pigments and dyes are dispersed in paints and caulk to provide characteristics such as color, hiding power, bulk, durability and corrosion resistance.

Helium neon (HeNe) lasers have an emission that is determined by neon atoms by virtue of a resonant transfer of excitation of helium. They operate continuously in the red, infrared and far-infrared regions and emit highly monochromatic radiation.

Ballasts are power supplies or transformers for fluorescent lamps.
