Tesla has succeeded in making artificial daylight. In his laboratory he shows numerous balls of glass of different sizes which look like miniature suns. The balls are empty: there are no wires in them nor outside of them. They do not burn the fingers. The light does not hurt the eyes as sunlight and ordinary electric light do. A number of leading New York and Chicago photographers will have this artificial daylight supplied to their studios. Tesla says: “The reason I have chosen to introduce the new daylight to the photographers first is that I believe them to be the severest critics in the matter of light. If it succeeds with them a new light will succeed everywhere.” - N. Y. World.
