A heat lamp is an incandescent light bulb that is used for the principal purpose of creating heat. The spectrum of black-body radiation emitted by the lamp is shifted to produce more infrared light. Many heat lamps include a red filter to minimize the amount of visible light emitted. Heat lamps often include an internal reflector.

Reflectors (such as the moon, cat's eyes, and mirrors) do not actually produce the light that ...
Infrared heating uses infrared lamps, commonly called heat lamps, to transmit infrared radiation to the body that is being heated.
