Carbon Filament Lamp

Description (Brief)
This is an Edison carbon lamp with Thomson-Houston base and asphalt-coated filament that was developed around 1891. The lamp's base differed depending on the manufacturer of the lamp. Edison, Westinghouse, Thomson-Houston and other makers devised differing ways to attach a lamp to a fixture. Companies quickly began making adapters or, as in this case, making their own lamps with competitors’ bases.
