Heat lamps are also known as infrared emitters, infrared bulbs, infrared tubes, or infrared lamps.

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

High intensity discharge lamps (HID) contain compact arc tubes, which enclose various gases and metal salts, operating at relatively high pressures and temperatures.

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

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.

Infrared heaters use a reflective shield to direct radiant heat onto a heated surface
