High-voltage gaseous and fluorescent tubes for advertising and architectural lighting effects

Rapid strides have been made in the field of high-voltage electrical-discharge tubes. The most recent development has been the use of fluorescent phenomena. Fluorescent materials were first introduced as an integral part of the glass. The New York World´s Fair has made a number of installations of Claude Zeon fluorescent tubes in which the fluorescent materials are placed as a coating on the inside walls of the tubing. Remarkable efficiencies and a full range of pastel shades make high-voltage fluorescent tubing a valuable tool for the use of the engineer, architectural designer, and advertiser.
