The history of screen lighting, in which National Carbon Company has played a major role since the very beginning. records a continuous How of improvements to obtain more and better light. Even today, with light levels which were considered unbelievable not long ago, progress has not stopped. Year after year the table above has been revised to include new carbons or improved carbons with one objectiveia better and brighter light

at the lowest possible cost.

Today every theatre in the country, large or small, can have snow-white projection light of sufficient intensity to prmide a clear cut image on the screen, and a safe and comfortable level of general illumination in the audi torium. Each of the arcs listed above supplies light of

buggyeand are just about as popular.

Check today to see if your projection light is sumlciently bright to reflect in your boxotfice.
