A portable headlight assembly for illuminating a surgical site when look at by a practitioner and moves with the surgeon operates only when the light energy is directed toward the site. A headlight source has a HID lamp to illuminate via a light cable coupled to receive and transmit the illumination in the range of natural daylight between 5000 and 6700 degrees Kelvin. A power supply couples to the HID lamp when the light cable is located to receive focused light from it. A control monitors the operation of the headlight source and the portable power supply and is responsive to temperature of the portable power supply and radiation supplying illumination. The light cable extends between the HID lamp to guide illumination from the HID lamp and its reflector to a lens In a head strap worn by the practitioner for delivering the illumination towards the surgical site to enhance the color spectra of the visual field during surgery providing observation with depth of field and natural coloration. A method of using the portable headlight safely to illuminate a surgical site has steps of positioning it for movement by or with the surgeon. Supplying illumination at the surgical site with a headlight source having a HID lamp able via a light cable when coupled to make, receive and transmit illumination in the range of natural daylight between 5000 and 6700 degrees Kelvin and energizing with a portable power supply if coupled to the HID lamp when a light cable is located to received focused light from the HID lamp for operating the HID lamp when the light energy is directed toward the surgical site are steps. The step of monitoring the operation with a control responsive to temperature of the HID lamp and the portable power supply wherein the control responds to the level of heat in the portable power supply, and the headlight source. Extending the light cable between the HID lamp and a mount positioned on the head of a surgeon is a step for aiming the illumination toward the surgical site for enhancing the color spectra of the visual field during surgery providing surgeon observation including depth of field and natural colorations during surgery.
