The FLE500AS movable operating lamp uses special infrared filter technology to filter 99% of the radiant heat and maintain the temperature in the patient’s wound area at below 10°c, thus eliminating the risk of water evaporation in the wound area. The color temperature calibration system is specially designed to provide a color temperature that is closest to natural daylight, reflecting the original colors of the body tissues to allow physicians to correctly diagnose the area to be operated.
