Such an instal-lation will produce an intensity of approximately 12 foot-candles. In the particular case shown and in the night views in Figs. 1and 2, practically the entire room is devoted to composing framesand larger lamps on wider spaces might be employed, providing theceiling was of sufficient height, say 15 feet, to allow for a spread oflight.
