Abstract: A device and method of operation are disclosed which provide an improved light source. The device and its mode of operation serve to substantially reduce the energy required to produce sufficient light for normal human vision. A mechanical embodiment of the device serves to concentrate the total output of a light source into one or more relatively small beams, then sweep the beams of light around or over an area to be illuminated for vision.
