The Calculation of Illumination by the Flux of Light Method

Oct 02, 1908

It is the object of this paper to give certain methods employed by the authors for a number of months past in calculating the illumination of large interiors and to show the practical application of the excellent suggestions made by Dr. Clayton H. Sharp in his presidential address before the first annual convention of the Illuminating Engineering Society at Boston July 30, 1907. The authors expressed the opinion at that time that the simple methods suggested by Dr. Sharp would be of considerable practical value, and immediately upon the close of the convention worked out methods of applying them in every-day engineering practice.
