THE STANDARD DIRECT CURRENT MOTION PICTURE CARBONS
The Silvertip carbon used with a Columbia upper gives a light source that is hard to beat. The Silvertip is a quality product that has received the stamp of approval of the best operators in the country.
The Columbia-Silvertip combination gives:
1. Absolutely steady screen illumination free from Dickering shadows. The small diameter of the Silvertip causes it to burn with a sharp point which keeps the arc steady, and also eliminates the shadows on the screen.
2. A powerful, flexible light source. The are can be varied at the will of the operator, according to the density of the film, within a reasonable limit of the rated amperage of the combination used.
NOTE: Silvertips are for direct current only.
