Abstract
Color-temperatures of various carbon arcs have been calculated from spectral energy data. The dominant wavelength and per cent purity of each arc are given with reference to both “Average Daylight” and “Noon June Sunlight.” It is pointed out that the color-temperatures of these carbon arc light-sources are of value in comparing them on a visual basis only. The effect of the radiant energy from the arcs upon any photosensitive medium other than the human eye, for example, photographic film, is very different from the visual impression. Spectral energy distribution curves of several carbon are sources are published for the first time.
