Trend of Lamp Development and Operation in Motion Picture Projectors Employing 16 mm. Film

We have had to alter our conception of the application of the non-professional projectors employing 16 mm. film. It was formerly felt, that due to inherent limitations in illumination, these small units could only be recommended for use before a handful of people. However, due to their portability, comparatively low cost, and low film cost, they have become increasingly popular. While one of their major applications is in the home, they have become an important sales aid in the business field and find increasing use in the school classroom.
