3. How does the shadow management system work on the Harmony LC?

The shadow management system on the STERIS Harmony LC is one of its most advanced features. It uses multiple independent LED arrays arranged in a circular pattern within the light head. Each array can be individually controlled to adjust its brightness and direction. When an object, such as a surgeon’s head or hand, blocks some of the light, the system automatically compensates by increasing the output from the unblocked arrays. This ensures that the surgical field remains uniformly illuminated, with minimal shadowing. The system also includes a feature called “Virtual Shadow Management,” which uses software algorithms to predict where shadows will fall and adjust the light distribution accordingly. This is particularly useful in deep cavities where even a small shadow can obscure critical anatomy. The result is that surgeons can work more confidently without having to constantly reposition the light. The system’s ability to maintain consistent illumination even in challenging conditions is a key reason why many surgical teams prefer the Harmony LC over other lights.

4. What are the available color temperature settings and how do they affect surgery?
