Abstract :
To conserve critical materials which would be necessary to build new plants and to save the time required for construction, existing manufacturing plants are being pressed into service for war production. Many of these plants have inadequate lighting facilities. This article suggests that present lighting sources in such plants be supplemented by placing at strategic working points high-intensity fluorescent local lighting with light-hoods or reflectors. These reflectors, no longer made of steel because of wartime restriction, are now being formed successfully from fibrous materials.
