Infrared radiation consists of magnetic waves at a frequency that is invisible to the naked eye, but which we feel as warmth on our skin. 

The frequency of the waves emitted by the carbon and special halogen heating elements enables our skin to absorb over 4 times more heat than another other product using a quartz element or an ordinary halogen lamp. The amount of heat perceived by the user is actually 4 times greater than with an ordinary heater.
