- Perkins Light Socket, circa 1890 - A light socket provides a secure connection between an incandescent electric lamp and the electrical circuit. In the late 19th century, companies created lamp bulb bases with unique styles and sizes which would only fit sockets that they made. By 1910 the Edison screw-type base had become so popular it was virtually an industry standard, and consumers no longer had to buy lamps and sockets from the same manufacturer.
