Abstract
IN the Engineering Supplement to the Siemens Magazine of February 1941, there is an instructive article by Mr. C. J. Misselbrook on “Factory Lighting in War Time”. The fifth report of the Departmental Committee on Lighting in Factories issued in June 1940 has given a number of important recommendations on this subject and indicates a minimum standard which, although it would have been regarded a few years ago as unnecessarily lavish, is now in accordance with all good modern lighting practice. The recommendations of the report may be divided into two sections, adequacy and suitability, each of which presents its own problems. War conditions have resulted in the introduction of unskilled or semi-skilled workers into the industrial world and the work of training them is greatly facilitated if they are not expected to strain their eyes on unfamiliar tasks with inefficient lighting. In addition, the calling up of young men and their replacement by older workers increases the need for good lighting, for as a rule the eyes of older people are not so efficient as those of the younger generation, and consequently need more light for the equivalent 'seeing conditions'.
