New 13.6-mm Carbons for Increased Screen Light
A new 13.6-mm super high-intensity carbon designed for 170-ampere operation gives a substantial increase in light over either the old 180-ampere 13.6-mm super carbon or the 125 to 150-ampere new regular 13.6-mm carbon described previously.6The new regular and super carbons are compared with the old carbons as to light available on the screen and as to efficiency of light production.
