Abstract: The fact that there are today in operation approximately one thousand motion picture machines using the tungsten filament lamp as a light source proves that the incandescent lamp is a success in this field. The history of the developments which were gone through to achieve this success is very interesting. Some of the lamps and apparatus, which a short time ago seemed marvelous, today appear almost crude. However, we shall not take your time to describe the discouragements and the achievements along this line during the past three years. Nor shall we devote much time to description of the fundamental differences between the are and the incandescent systems. This data is already more or less familiar to you, through papers presented before your Society, through articles in the trade journals, and through commercial advertising of the concerns manufacturing projection equipment.
