Abstract :
F. P. Kuhl, in his article entitled “New-Indirect Luminaire Improves Drafting-Room Illumination,” (Electrical Engineering, February 1940) showed one method by which a lighting installation may be improved and modernized to give better seeing conditions. As may be observed from his figures 4 and 5, the improvement in lighting was quite appreciable when the old-style milk-glass globes were replaced by specially developed louvered units utilizing 200-watt bowl silvered lamps.
