The MAQUET PowerLED Major Surgical Lighting System is designed to enhance the comfort of the surgical team especially during lengthy procedures. Unlike halogen lighting, LED illumination emits virtually no infrared or heat. The PowerLED delivers 30,000 hours of illumination and requires no focusing or manual lighting adjustments. In addition, the appearance of wall cavities is the same regardless of the position of the light head over the surgical area, even when a number of LEDs are obstructed. The PowerLED emits no ultraviolet light and incorporates secondary ambient light with five easy-to-adjust illumination levels. It can also accommodate the addition of flat screens and cameras.
