1. An illumination source for illuminating a target, comprising:

  • an elongate mounting base having opposite first and second surfaces and a heat sink extending along the length of the mountain base;

    at least one right printed wire board segment;

    at least one left printed wire board segment separate from said right printed wire board segment;

    a plurality of LEDs mounted at equally spaced intervals along said heat sink whereby heat transfer is provided from the LEDs to the mounting base, each LED of the plurality having a cathode lead attached to one of the at least one right printed wire board segment and the at least one left printed wire board segment, and each LED of the plurality having an anode lead attached to the other of the at least one right printed wire board segment and the at least one left printed wire board segment;

    a support base attachable to the second surface of the mounting base, the support base having a first length, the base constructed from a heat transferring material, the support base comprising a plurality of interior channels extending the first length;

    at least two support members attached to the first surface of the mounting base such that the plurality of LEDs are located therebetween, each of the at least two support members comprising a mirrored surface adjacent the plurality of LEDs for directing illumination produced by the plurality of LEDs towards the target;

    a window attached to the at least two support members;

    at least two brackets having the first length for enclosing the mounting base, the at least two support members, and at least a portion of the window; and

    at least two end caps for enclosing a first and second end of each of the at least two brackets.
