1938 - Chicago is experimenting with the golden light from sodium lamps

CHICAGO'S GOLDEN LIGHT

CD 1966018 E&MP27.102

Electric Lighting

April 20, 1938


BEFORE AND AFTER SODIUM ILLUMINATION IN CHICAGO

Chicago is experimenting with the golden light from sodium lamps, developed by General Electric scientists, at three main intersections with heavy night accidents.

The special illumination is under the observation of the Utilities Research Commission, Inc., and has been in operation at 79th Street and Stony Island, Chicago and Ashland Avenues, and Diversey and Cicero, since last November.

Records show a night accident decrease with the new lamps, but they must remain in operation for at lease a year before a thorough analysis can be made into their worth to the public. The attached [27.103 & 27.104] pictures show the illumination at the intersection of Ashland and Chicago Avenues before and after sodium lighting.
