Shadows exist in surgery, created by surgeon position, surgical team movement, equipment or the depth of a wound. The key is to minimize shadows so a surgeon always has the clearest possible view of the surgical site. Enertech LED light insures the relation between light body and light field diameter to perform an optimum illumination of the OT field in terms of area and depth. The Enertech reflectors are designed to construct a number of light beams to dissolve the shadows.
