There will in all probability be two aspects of wartime lighting : lighting for efficiency and lighting for protection.

LIGHTING FOR EFFICIENCY  The chief interest in lighting for efficiency will probably be in industrial lighting to increase the speed of production. As one of the ways of accomplishing this purpose, high intensities will doubtless be used, perhaps excessively high. These intensities will be fatiguing to the eye unless special care is taken to have well diffused light and to eliminate all glare and high brightness from the lighting fixtures themselves and from the field of view. For eliminating glare and high brightness a suitable use of glare baffles, or louvers, should be made. There is great need in wartime for a special development of louvered low brightness lighting. Even with the glare eliminated from the fixtures and the field of view, the use of excessive intensities of light on the plane
