Also known as short wave infrared heaters, transmit heat through electromagnetic radiation, making them efficient and rapid heating solutions. They are commonly used in industrial applications like paint curing, heating plastics, and drying processes. SWIR lamps operate in the 0.9 – 1.7 μm (or sometimes 0.7 – 2.5 μm) wavelength range. They are known for their high efficiency in converting electrical energy into heat, with some reaching 80% efficiency.
