Banker's lamp
The banker's lamp has its origins in the United States with the introduction of the Emeralite. This is a style of electric desk or table lamp characterized by a brass stand, green glass lamp shade and pull-chain switch (though modern versions may make use of alternate switch types). It is often used in libraries throughout the United States, which have made the lamp popular through their presence in films and TV series. Other examples can feature different colours of glass.

History
The first patent for a banker's lamp was filed on 11 May 1909 by Harrison D. McFaddin and were produced and sold under the brand name Emeralite ("emerald" and "light"). Emeralite lamp shades were produced by the J. Schreiber & Neffen factory located in the city of Rapotín, Moravia.[1] Later competitors were sold as "Greenalite", "Verdelite", and "Amronlite".[2]

A British version of the banker's lamp was filed for a patent in 1929, which instead of a glass shade has a solid brass shade or reflector. In addition, the positions of both the pedestal and the shade are adjustable.[3] Examples are commonly seen on the second-hand market.
