Evaluation: Getinge Maquet PowerLED II 500 Major Surgical Light
December 20, 2019 | Evaluations & Guidance
- The Getinge Maquet PowerLED II 500 is used to provide high-quality, consistent, and shadow-free illumination for surgical teams to see into deep cavities in a patient's body.
- An optional full high-definition (HD) video camera may be mounted in the central light handle to provide controllable views of the surgical site, which may be transmitted to video monitors around the OR; not all PowerLED II light heads are camera-ready.
- Major device components and features:
- A total of 56 LEDs, with specially designed collimators intended to focus beams of light as a means of shadow dilution. There are no moving parts within the light head—a design intended to reduce service burden.
- Maximum light illuminance intensity: 142,000 lux, as measured by ECRI, which increased to approximately 145,000 lux with the available BOOST feature
- Getinge Maquet specifications are a maximum intensity of 140,000 lux, with BOOST increasing the intensity to 160,000 lux.
- There are 10 intensity settings from 13% to 100% illuminance, plus BOOST functionality. The light also has a dim ambient mode with six selectable colors (white, yellow, green, turquoise, blue, and purple), each with five adjustable intensity settings, for procedures requiring low light.
- Automatic Illumination Management (AIM)—patented functionality that automatically compensates for the loss of illumination when certain LEDs are obstructed, by increasing power to the remaining LEDs by up to 20%. Getinge claims this has no impact on LED life and does not exceed rated voltage. This feature is standard on the PowerLED II.
- BOOST—exclusive functionality that maximizes light output if required by the conditions of the surgery. BOOST mode is indicated by flashing of the uppermost LED on the intensity controls. Note that when BOOST is enabled, AIM does not function. BOOST is standard on the PowerLED II.
- LMD—The Luminance Management Device (LMD) is an optional module that can be exchanged with the central sterile handle or camera. It is intended to automatically regulate the illumination that reaches the surgeon's eyes—for example, as a result of a high illumination bouncing off a particularly reflective surface—to reduce eye fatigue.
- Comfort Light—a broad ring of light projected around the light field intended to reduce the contrast between the extremely bright light field and more dull adjacent surfaces within the surgical field. Getinge Maquet claims that this reduction in contrast helps to minimize eyestrain and visual fatigue to improve surgical outcomes. This feature is optional but must be selected at the time of purchase and cannot be added to an existing installation. Customers wanting the Comfort Light must also get Getinge Maquet's touchscreen controller, because that is the only way to control the Comfort Light.
