Banker's lamp

The banker's lamp is a style of electric desk or table lamp often characterized by a brass stand, green glass lamp shade, and pull-chain switch. Such a lamp was first patented in the United States under the Emeralite brand name. These types of lamp are frequently 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 and alternative switch types.

The color green was commonly used for the lamp's shade as it was believed to prevent eye strain and to have a calming psychological effect (similar to the use of green eyeshades).
