Evaluation: Draeger Polaris 600 Major LED Surgical Light

February 13, 2019 | Evaluations & Guidance

Preview

  • The Draeger Polaris 600 is used to provide high-quality, consistent, and shadow-free illumination for surgical teams to see into deep cavities in a patient's body.
  • A wireless high-definition (HD) video camera is enclosed in the lower glass of the light head (so as not to require an additional sterile handle) to provide controllable views of the surgical site that may be transmitted to video monitors around the OR; all Polaris 600 lights are equipped with wireless video transfer technology.
  • Major device components and software features:
    • Ninety-two LEDs (arranged in 18 zones), intended to redundantly overlap beams of light into a homogenous light column as a means of shadow dilution
    • Maximum light illuminance intensity: approximately 160,000 lux, as measured by ECRI Institute
      • Twelve intensity settings from approximately 15% to 100% illuminance, as measured by ECRI Institute, plus a dim endo mode (approximately 3,000 lux) for procedures requiring low light
      • The Polaris 600 has a sync feature for installations with multiple light heads—when it is active, all light heads will output the same intensity setting if only one is changed.
    • High color rendering index (CRI) values of 95-96, depending on color temperature
    • Four values of color temperature (3,800 kelvins K, 4,400 K, 5,000 K, and 5,600 K) for different specialties or surgeon preference
    • Claimed LED life of 50,000 hr
    • Large light head diameter of 62.0 cm (24 in) with LEDs spanning approximately 55.9 cm (22.5 in) (1) Draeger offers the Polaris 100 and Polaris 200, medium-diameter LED light heads that output 40,000-120,000 or 40,000-160,000 lux, respectively, and offer slightly different performance characteristics than the Polaris 600 we tested.
