Book excerpt: Excerpt from Color and Spectral Composition of Certain High-Intensity Searchlight Arcs The development of high - intensity arcs by the use of specially prepared carbons has resulted in the production of a light which is very blue relative to artificial incandescent sources. In a general investigation of searchlights, including the effectiveness and suitability of their illumination for various purposes, it appeared desirable to have at least approximately quantitative data on the color of this light. An investigation was made with the cooperation of the Search light Investigation Section, Corps oi Engineers, U. S. Army. A report was issued to the Corps of Engineers and others January 2 3, 1919. Another report was made to the American Physical Society, April 25, These reports are combined in the present paper.
