content: Nernst Lamp with Westinghouse plug on cord, 1902. Invented by Walther Nernst, this incandescent lamp could operate in open air and did not violate Edison’s patents. The housing is sectioned for study of the internal ballast resistance mechanism. The glower consists of three iron rods coated with rare-earth elements. The coating gives off light when heated and protects the rod from oxidation.
