Electric Lighting

1941

A giant steel sphere split in two serves as a testing chamber in Westinghouse Laboratories for powerful 400-watt mercury vapor lamps which may soon rekindle the Statue of Liberty’s torch. S.G. Hibben, Director of Applied Lighting, examines the glass capsules for the quality and distribution of their rays.

Batteries of these lamps, tests reveal, can make the torch visible for 10 to 20 miles at sea.

New electric beauty treatment for the 55-year old Goddess will include floodlighting for her copper robes. The blue-green hue of mercury vapor lighting would change the color of the monument for the first time since 1886.
