Brass banker's lamp with green glass shade

The banker's lamp, also known as an Emeralite or library lamp, originated in the early 20th century, designed specifically for office and library use. The distinctive green glass shade was engineered to reduce eye strain for those working long hours with paperwork, while the brass base provided stability and elegance. These lamps became iconic fixtures in financial institutions, libraries, and professional offices throughout the early-to-mid 20th century. Today, banker's lamps are highly valued by collectors of vintage lighting, interior designers seeking authentic period pieces, and enthusiasts of Art Deco and early 20th century office memorabilia for their classic design and functional elegance.
