Reflector and light systems include collecting and back reflecting surfaces that efficiently collect the energy produced by a light source and redirect the light back through the collecting surface without restriking the collecting surface or the light source. The reflected light does not reach the focus for the back reflecting surface until the light exits the system. A lens-end bulb may be used as the light source to produce a projected cone of light that is focused on a target that is positioned in front of the second focus and a reflected cone of light that is focused on the same target. In one form of the invention, the back reflecting surface is eliminated to permit the projected light to be focused on one target located externally of one end of the system and the reflected light to be focused on another target located externally of the other end of the system.
