Incandescent lamps have continuous emissions of light because they work by heating a filament wire until it glows and produces light. This continuous emission of light comes from the constant heating of the filament by an electric current passing through it.
Infrared waves from the electromagnetic spectrum are used in heat lamps and heat sensing devices.
Infrared waves are often used in heat lamps because they can penetrate the skin and generate heat without heating up the surrounding air. This makes them ideal for providing targeted warmth in applications such as heat therapy or outdoor heating.

They do not necessarily need heat LAMPS at all times but they usually require some source of heat. Captive snakes may have a heating lamp or a heating pad or in hotter parts of the world may not require heating. In the wild they do not need heating lamps. They use the sun and may go under ground when it is too cold.
