Abstract
FOR a number of years there have been commercially available several flame arc carbons which produce light of various colors but there have been no data generally available as to the visual candle power or the distribution of the energy of these lights in various parts of the spectrum until the publications by Coblenz, Dorcas, and Hughes<sup>1</sup> and M.J. Dorcas<sup>2</sup> within the past two or three years. These publications have given data as to the energy distribution of some of these arcs but nothing as to the visual candle power and the energy efficiency. Their data also, are as a rule, not at currents and voltages ordinarily encountered in the studio.
