IN 1955, the lighting industry celebrated Light's Diamond Jubilee commemorating the invention of the incandescent filament lamp and the birth of electric utilities in the form of Edison Electric Illuminating Companies. A feature of this celebration was a 75-kw incandescent lamp constructed especially for this use, just as a 50-kw lamp had been made for exhibit at the New York World's Fair in 1939. This mammoth lamp, burned from time to time for demonstration during the celebration, should not be taken to indicate that advance in lighting has been solely in the size of the source.
