1. A phototherapy light engine comprising:
a) a thermally conductive core substrate having a first and a second surface;
b) a plurality of light emitting diodes (LEDs) for emitting light comprising phototherapeutic component wavelengths, the plurality of LEDs configured to couple with said first surface of said thermally conductive core substrate, said thermally conductive core substrate for absorbing heat from said plurality of LEDs;
c) a window positioned to cover at least part of said first surface of said thermally conductive core substrate;
d) a collar assembly coupled to said first surface of said thermally conductive core substrate, said collar assembly comprising a reflective surface on an interior surface of the collar assembly, and said collar assembly adapted to engage the skin surface and to limit escape of the emitted light from the skin surface and a surrounding area;
e) a heat sink coupled to said second surface of said thermally conductive core substrate, wherein said heat sink is configured and adapted to conduct heat away from said thermally conductive core substrate;
f) a receiver to receive input from a remote computing device; and
g) a transmitter to transmit performance data of the plurality of LEDs.
