1. Visibility: Medical procedures often require precision and accuracy, which can only be achieved with good visibility. Proper lighting can improve visibility and reduce the risk of errors, making procedures safer and more effective.

2. Color rendering: Correct lighting can help ensure accurate color rendering, which is important for medical procedures where color differentiation is critical. For example, in surgery, accurate color rendering can help distinguish between healthy and diseased tissue.

3. Eye strain: Medical professionals often work long hours, and incorrect lighting can cause eye strain and fatigue. Proper lighting can help reduce eye strain, improve visual comfort, and increase alertness.

4. Infection control: Medical facilities require lighting that is easy to clean and maintain to prevent the spread of infection. Proper lighting design can ensure that fixtures are easy to clean and free from bacteria and other pathogens.

5. Patient comfort: Proper lighting can also help improve patient comfort and well-being. Bright, harsh lighting can be uncomfortable and cause anxiety, while dim or poorly lit areas can be disorienting. Correct lighting can create a calm and welcoming environment that promotes healing.

Overall, correct lighting is crucial for medical procedures as it can improve visibility, accuracy, safety, and patient comfort. By designing lighting systems that meet the specific needs of medical facilities, healthcare professionals can provide better care and improve patient outcomes.
