Infrared Heater or heat lamp, is actually a human body with a higher temperature which transfers Electrical power to some entire body which has a decreased temperature through electromagnetic radiation. Dependant upon the temperature of your emitting overall body, the wavelength of the peak with the infrared radiation ranges from 780 nm to one mm.
