Abstract

The minimum light intensity required for comfortable reading depends on a number of factors. The test here reported was made with a group of students of Iowa State College and it should be emphasized that the results sought were minimum intensities for the sake of making comparison between different types of lighting possible. The maximum intensity permissible would doubtless be found much farther from that ordinarily recommended than is the minimum.
