Abstract
A new 6-mm experimental carbon is described which makes it possible to project 2 1/2 times as much light for 16-mm film as the present 6-mm “Pearlex” high-intensity carbons. A 7-mm “Suprex” carbon offers twice as much light as the ”Pearlex” carbon and longer burning life than the 6-mm experimental carbon. Measurements of radiant energy intensity at the film aperture and spectral composition are given.
