Excerpt from Illuminating EngineerThe discussion on this subject opened by Professor J. T. Morris at the last meeting of the Illuminating Engineering Society (see pp. 5 - 26) brought out several interesting points. Methods of lighting interiors are necessarily affected by the range of candlepower and efficiency Of the lamps available, and it is not surprising to find that as a result of the introduction of more powerful and efficient incandescent lamps general over-head lighting is being exploited to a considerable extent in many cases where local lighting with low candlepower lamps would formerly have been used. The rise in intrinsic brilliancy (which according to Professor Morris reaches over candles per square inch in the case of the half - watt lamp), has made proper methods of shading essential, and given some encouragement to the use Of indirect and semi-indirect methods Of lighting.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
