The Illinois State Capitol Building in Springfield (1868-1888) was primarily designed by Alfred Piquenard, who also designed the Iowa Capitol.
Lighting fixtures were supplied by the Mitchell-Vance Company, which had taken first place at the 1876 Centennial Exhibition and was the number one supplier of institutional scale gas lighting during this period. The original House Chamber gasoliers, shown here, were modified, probably after the South Wing fire, to be electric flush mounted fixtures exhibiting the bottom tiers of the chandeliers only.
Using historic photos, SLALCO redesigned and remanufactured the fixtures to their original design and scale. An uplight system (hidden from view in the body of the fixture) was designed and installed on a separate circuit to wash the ornate gilded ceiling with light. The entire system is dimmable, allowing the chandeliers to be dimmed to light levels approximating those of gaslight in 1888. Fixtures on the Rostrum and the Chamber wall sconces were also replicated from historic photos. Since there were not historic photos of the original corridor lighting, a family of fixtures was designed to match the style of the grand crystal gasoliers.
