Fluorescent lamp demonstration fixture

Description (Brief)
This fixture was part of a sales demonstration kit for early fluorescent lamps. The unit has a metal case that’s open on two sides and includes a ballast, two fluorescent lamp-holders, two Lumiline lamp-holders, a toggle switch and a ten-foot power cord. The power cord is not original and has been spliced onto the unit. Linear incandescent lamps called Lumiline were popular in the 1930s. Their end-caps consisted of a flat disc that snapped into the holder. GE engineers designed two types of fluorescent lamps with that style connector so as to save money by using existing production equipment.
