LAMP RIVALS SUN
CD 1964060 E&MP27.020
An experimental 10,000 Watt mercury-vapor lamp set wrapping paper a short distance away afire when S.G. Hibben, Director of Applied Lighting, Westinghouse Lamp Laboratories, Bloomfield, N.J. displayed it to a conference of university deans and professors, Oct. 18. The lamp. one-fifth as bright as the surface of the sun, is completely surrounded by a cooling-jacket carrying running water. Nevertheless, infra-red radiations fought through the lampís water-jacket to fire the paper in a few seconds.
