Abstract
A new high-intensity carbon trim has been developed for the projection of 16-mm film. The characteristics, operating data, and performance of this “Pearlex” trim are described. The light from the original combination of carbons has been modified to give a color quality suitable for 16-mm color-film which has been processed for projection with incandescent lamps. Measurements show that this new combination, in lamps specifically developed for it, provides approximately three times as much light as was hitherto available for 16-mm projection, thus greatly improving the projection of 16-mm film to large audiences.
