New High Intensity Rotating Positive Carbons for Motion-Picture Projection
New 10mm and 11mm High Intensity Projector carbons have been developed for rotating positive-carbon-type motion-picture projection lamps. These carbons, designed for 95-110 and 110-120 amp, respectively, give substantial increases in light and efficiency, and operate with greater stability than former carbons of the same size and type. Performance data are presented.
