Illuminance determines how bright the surgical field is, while CRI and R9 determine how safe the surgery is. As global medical standards become stricter, high-color-rendering LED surgical lights have become the mainstream choice for modern operating rooms. When purchasing surgical shadowless lamps, always take Ra ≥95 and R9 ≥50 as the basic threshold, and select R9 ≥50 high-precision configuration for complex surgeries. Scientific CRI parameter matching effectively improves surgical accuracy, protects patient safety, and reduces the work fatigue of medical staff.
