The glare and “hot spot” of the ordinary household light bulb shown at right has been completely eliminated in a new type bulb introduced by Westinghouse today.

The new Eye Saving white bulb is especially suited for reading and close seeing tasks, according to F.M. Sloan, Westinghouse vice president. A new process coats the interior of the bulb with millions of special glare-deflecting particles. The particles break up the usual spotlight glare from the filament. The result is soft, glareless light which is radiated evenly from the entire bulb surface instead of one blinding spot, Mr. Sloan reported. With bounce-back glare practically eliminated, reading becomes more comfortable, less tiring to the eyes.

Developed by engineers of the Westinghouse lamp division, the new Eye Saving bulb has a greater surface area than an ordinary bulb although outer dimensions are no greater. This larger area permits more silica coating on the inside of the bulb, Mr. Sloan explained. Since this silica coating is the diffusing material, better distribution of light and substantially less surface brightness results.
