What are green lamps called?

One very popular green lamp is called a banker’s lamp. The first patent for a banker’s lamp was in 1909 and was sold under the name Emeralite, for emerald light. These lights were made by the J. Schreiber & Neffen factory and soon prompted knock-offs called Greenalite, Verdelite and Amronlite. Shop a collection of banker’s lights from some of the world’s top sellers on 1stDibs.
