A light engine ( 16 ) includes at least one LED ( 12 ) for generating light of one of a plurality of wavelengths. The LED ( 12 ) is disposed on the magnetic core printed circuit board ( 14 ). A heatsink ( 26 ) is disposed in thermal communication with a base ( 24 ) and the LED ( 12 ) for conducting thermal energy away from the LED ( 12 ). The light engine ( 16 ) is magnetically attached to the heatsink ( 26 ) via a magnet ( 50 ) which is attached to the heatsink ( 26 ) to create that a magnetic force between the magnetic core board ( 14 ) and the heatsink ( 26 ).
