Abstract
Methods and apparatus involving at least two LEDs configured to generate at least two different spectra of radiation that are combined to produce white light. At least one parameter of the at least two different spectra of radiation generated by the at least two LEDs is controlled, based at least in part on at least one lighting control signal received by the apparatus over at least one wireless communication link, so as to control at least a color temperature of the white light.
