- Description (Brief)
- 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 an iron rod coated with rare-earth elements. The coating gives off light when heated and protects the rod from oxidation.
