1. A high-output LED light source comprising:
at least one LED;
a circuit board, wherein the at least one LED is mounted on a first side of the circuit board; and
a spiral planar heat sink, wherein the spiral planar heat sink comprises a continuous spiral coil forming a plurality of windings, the windings continuously extending radially outward from a center axis, such that successive windings fall within a common plane, wherein the spiral planar heat sink is thermally bonded to a second side of the circuit board.
