Abstract: The present invention provides a method of controlling a light output of a surgical lamp used for illuminating a surgical site. The surgical lamp includes a housing that defines an internal cavity. A light source is disposed within the internal cavity of the housing. The light source produces a light path and a light field at a surgical site that is remote from the housing. The method comprises providing a voltage sensitive device along the light path, the voltage sensitive device having light transmissive properties that change in response to a biasing voltage applied thereto, and applying a biasing voltage to the voltage sensitive device to achieve a desired light intensity at the surgical site.
