The quality of a surgical light plays a fundamental role in the context of surgery, directly influencing the results and patient safety. The certification process for this equipment is governed by various standards, including NBR IEC 60601–2-41. In this study, two surgical lights installed in the operating room were selected, one with an LED lamp and one with a halogen lamp, from the University Hospital of the University of São Paulo. The experiments were conducted utilizing the surgical lights at their maximum intensity values. A photometer was positioned centrally at a distance of 1 m from the lowest part of the surgical lights to capture luminance data at specified points along vertical and horizontal axes, with measurements taken at 1-cm intervals. Additionally, a reflectance standard was employed, also centrally positioned 1 m from the surgical light, facilitating spectroradiometric measurements. A spectroradiometer was angled at 45 degrees and placed at a distance of 50 cm from the reflectance standard to acquire characteristic data of the emitted light. These datasets were then processed using dedicated software to derive precise values of the lights under examination. The results in relation to the optical requirements were measured and evaluated according to the requirements of the standard. Both lights performed adequately in relation to the requirements of the standard.
