Infrared heat lamp 125x170mm Infrared heat lamp R125 E27 clear. This lamp is a special short-wave infrared lamp (IR-A) for technical applications. The radiation maximum is around 1,100 nm. In conjunction with a paraboloid-shaped internal reflector, which focuses the infrared rays to a high intensity, these heat lamps achieve an optimal depth effect in the irradiated materials. The main advantages of heating with this lamp are its short response time, precise controllability and high efficiency. Energy efficiency class: not subject to labeling Mercury content (mg): 0 Switching cycles: 20,000
