Systems and methods for projecting motion pictures using a light source comprising an electrodeless lamp (12, 54). The electrodeless lamp (12, 54) may be used with a motion picture film projector or a so-called "digital cinema" projector, as well as a projector for projecting still images. The electrodeless lamp (12, 54) may be operated in a pulsed mode, thereby eliminating the need for a shutter in a typical film projector. The light source also may employ a plurality of electrodeless lamps (32, 61, 62, 63, 64, 65, 66, 80). Each lamp may be selected to provide radiation corresponding to a different spectral composition. For example, the lamps may emit red, blue, and green light to illuminate a plurality of "Digital Micromirror Devices" (58) or other digital imaging means.
