Frequently Asked Question
There are primarily two types: Ceiling-mounted operating lights Mobile or floor-standing operating lights Some systems also include wall-mounted or hybrid lights for specific needs.
LED lights offer a longer lifespan, better energy efficiency, and lower heat emission. Halogen lights tend to be less expensive initially but generate more heat and have shorter lifespans.
A high CRI (typically >90) ensures that tissue tones and subtle color differences are clearly visible, which is crucial for accurate diagnosis and surgical precision.
Yes, most modern surgical lights offer adjustable brightness and color temperature (typically between 3,500K to 5,500K) to suit different procedures and surgeon preferences.
Shadow dilution refers to the light’s ability to maintain consistent illumination even when parts of the light field are blocked (e.g., by a surgeon’s head or hands). This ensures visibility throughout the procedure.
