With a professional optical design and a large number of equally distributed LED light sources divided into ten independent light source groups, a uniform light spot and superb shadowless effect can be achieved. Each group of LED light source has an independent circuit control, the failure of any group will not affect the normal use of shadowless lamp, to ensure the safety of operation. The light head has an ultra-thin streamline design, and its 40mm edge completely satisfies the OR's laminar flow purification standards.
