STUDENT LAMPS: The student lamp originated in the kerosene-burning era of the late 1800's. It was designed to eliminate shadows and push the light downwards for studying. All manner of student lamps are designed around a center post with a loop to carry the lamp, and oil fonts and burner/shades on one or both sides. The popularity of the student lamp continued well into the advent of electricity and are even today still produced in a variety of styles, all of which follow the same configuration. As time went on, however, the tanks under the shades disappeared and the back tank became minimized. Both single and double student lamps take 7" or 10" student shades. Some smaller versions take 6" shades.

ROCHESTER LAMPS: Another common type of lamp which takes a student shade is a circa late 1880's - 1900's single-standing brass oil lamp with central draft oil burner, often referred to as a Rochester lamp. It is a term coined because of its association with the New Rochester Lamp Co. who pioneered improvements in center draft lamp burner. However, it was Edward Miller who prolifically produced this style of lamp under several different names including Juno, New Vestal, Ideal, Non Explosive, and of course, Miller. The Rayo lamp is another manufactured in Connecticut by the Bradley & Hubbard Manufacturing Company. All of these lamps take 10" student shades.
