“Near Infrared”, “IRA”, “Short wave” or “Bright” Infrared heaters and “Heat Lamps” operate between 0.75 to 1.4 microns and emit temperatures of 1300°C and more plus a bright red visible light. Emitters are typically Quartz with a reflector to concentrate the heat in a particular direction. There are also gas-fired Near Infrared heaters which burn propane or natural gas through a venturi to heat a steel tube, which glows sufficiently hot to produce the near infrared.
