A system of variable color landscape lights illuminated by multiple light emitting diode chips provides the user a controllable spectral output. In its various configurations, the electronic control system allows a selection of various spectral light radiation. The color output of the light emitting diode chips is electronically controlled and can be changed by means of a push button switch, radio frequency control, infrared control, signals impressed on line voltages, and other control system means.
