Caption: FILE PHOTO, March 9, 1965 - Rays from a 30-inch carbon arc searchlight produce more than 400 million candlepower, creating an aurora borealis-like effect above the St. Louis riverfront. The St. Louis Army Mobility Equipment Center put on the demonstration. The light, which was placed on the Jefferson National Expansion Memorial grounds just east of Third Street, was powered by a mobile generator and was 100 times more powerful than the searchlights used in World War II.
