x4 r$ JANUARY, 193! Page I INew Liffht Exceeds . . . Sun's Brilliancy M, .ODERN projection calls for a light source equaling and in some cases exceeding the brilliancy of the sun itself. Sound, color, and wide films, with long throws on porous screens now demanded by the modern theatre, have called for a most intense and active program of research and development to keep National Projector Carbons ahead of the requirements of modern projection. The concentration of large quantities of electrical energy in slender carbons, while keeping the light confined to a point source, represents a most remarkable advance in lighting practice. The results of this development program have been the production of National Projector Carbons of the highest quality with economies which make carbon cost* extremely low in comparison with other important items needed for the successful operation of the theatre. NATIONAL PROJECTOR CARBONS National Carbon Company will gladly cooperate ivith the producer, exhibitor, machine manufacturer or projectionist on any problem involving light. . . .
