Reflector and Torchiere Lamp Shades were originally used on early 20th century electric light fixtures. The goal of these newly designed lamp shades was to maximize light output. Working on the principle of reflecting light, these open top shades, known as IES reflector shades and Torchiere lamp shades offer a superior luminous quality. The IES Shades were designed for both table and floor lamps while the large torchiere shades were used predominantly on floor lamps. Offered in different sizes, select according to fitter diameter.
