| 1. A spot light, comprising:
a plurality of tight emitting diodes which produce electromagnetic radiation,
a plurality of lenses, and
a head section having an opening at one end,
wherein the plurality of light emitting diodes are within the head section,
wherein the plurality of lenses are within the head section,
wherein each of said lenses forms a beam of said electromagnetic radiation, with each of said lenses being associated with
one of said light emitting diodes in a manner that results in said beams being substantially superimposed with each other
at a target distance from the lenses outside the head section, and
wherein the optical centers of one or more of the light emitting diodes are offset outwardly, in a direction away from a center
of said head, from the optical centers of their associated lenses, to cause the radiation passing through the lenses to be
substantially superimposed to a target area at the target distance.
