The common approaches to solid state white lighting include phosphor conversion of blue or UV sources and combining red, green, and blue LEDs. However these methods only begin to address the reproduction of the complex, time-varying spectra humans call light. This paper will suggest a massive primary approach to solid state lighting and communication. LEDs allow an economic means to divide up the visible spectrum into many individually controllable slices, which can then be used in harmony to reproduce the desired illumination. It will also be suggested that the evolution and development of the radio frequency spectrum and high fidelity audio can provide guidance to exploiting the visible spectrum.
