1. A LED lighting system (100), comprising:

  • a LED light source (115) including a plurality of colored LEDs operable to emit one of a plurality of spectral outputs as a function of at least one current flowing through said plurality of colored LEDs, each current of the at least one current having a variable time average flow;

    a user interface (123, 124, 133, 134) operable to facilitate a first user selection of a first spectral output from the plurality of spectral outputs; and

    a controller (112) in electrical communication with said user interface (123, 124, 133, 134) and said LED light source (115) to control the variable time average flow of each current flowing through said plurality of colored LEDs as a function of the user selection of the first spectral output.
