- We Hand You a Hint: The Hemco Twin-Lite is Made of Condensite, circa 1915 - Chemically synthetic plastics were developed in the early 1900s to replace shellac and hard rubber -- naturally derived substances increasingly in demand for various industrial applications. The Condensite Company of America formed in 1910 to sell a new material first developed at Thomas Edison's West Orange laboratory for phonograph records. Durable and nonconductive, Condensite was well suited for electrical products.

- Key Socket - 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.
