The INP-MASTER / SL 300 surgical lights consist of fiberglass flame-retardant domes, designed for high performance in operation theaters, and feature specially-designed LEDs for medical applications with adjustable color temperature from 3200K to 5000K. The LED bulbs are connected in parallel so that should one bulb fail, the others remain on and allow to differentiate the tissue with accurate color reproduction that does not change the natural color of the blood or other tissues during surgery.
