A microwave powered ultraviolet and/or visible light producing system comprising a housing defining a microwave cavity having a volume Vo, an inlet and exhaust ports which communicate with the microwave cavity. Disposed within the microwave cavity and uniformly distributed therewithin are a number N of ultraviolet and/or visible light producing lamps, each of which has an inner diameter D, a length L, and a nominal power p. Communicating with the microwave cavity is a microwave magnetron generator having a microwave power P and producing microwaves having a wavelength lambda . Electrically connected to the generator is a power supply. The optimal operating condition for the system to maximize the ultraviolet and/or visible light output and longevity of the lamps and minimize system power consumption is governed by the relationships:Vo>/=V min 1 wherein V min 1=8 pi lambda 3/3;Vo>/=V min 2 wherein V min 2= pi (D+1)2N L/4;and wherein V min is the larger of V min 1 and V min 2, and k is a constant with a value in the range of 0.3</=k</=3, and pi =3.14.
