Microwaves from a highly efficient magnetron discharges the buffer gas in the bulb and the radiator vapor formed in the process then is excited by plasma discharges. The diatomic molecules generate broadband light over the visible range of the spectrum. The resulting light has a color that is closest to the sun light. Pure Plasma Lighting utilizes the technology that uses circularly polarized waves, making it possible to use a stationary bulb that is patented in many countries, including the U.S.
