1. A light emitting diode assembly comprising:

  • a light emitting diode package including;

    a front luminescent portion,a mounting base,a heat transfer plate on a rear surface of said mounting base, anda first and second contact lead extending from the sides of said mounting base;

    an interior mounting die, said interior die being thermally conductive, said interior die having a first end thereof configured to receive said mounting base of said light emitting diode, wherein said heat transfer plate is in thermal communication with said interior die;

    an exterior enclosure, said exterior enclosure being thermally conductive, said enclosure having a tubular outer wall with an interior surface and an exterior surface and a front wall with an aperture therein, said interior surface of said outer wall and said front wall cooperating to form a cavity for receiving said interior mounting die, wherein said luminescent portion of said light emitting diode extends through said aperture in said front wall, said interior die being in thermal communication with said exterior enclosure, wherein, in assembled relation, said light emitting diode, said interior mounting die and said exterior enclosure form a lighting head sub-assembly; and

    surface area enhancements extending outwardly from said exterior wall of said exterior enclosure.
