Abstract
A new 13.6-mm. super-high-intensity carbon is described which will burn at currents as high as 190 amperes and which has a higher intrinsic brilliancy and a more uniform distribution of light across the crater face than the regular 13.6-mm. carbon rated at 120 to 130 amperes. Tests comparing the light projected upon a projection screen by this new carbon and by the regular carbon show conclusively that the available light has been increased by at least 30 per cent. The arc lamp used with the carbons must be properly designed to take care of the increased current and carbon consumption.
