From the 1930s to the 70s, Aerolux Light Corporation sold lightbulbs with sculptural floral filaments. Now you can find them on Ebay for hundreds of dollars, at the time of production they were only 20 cents. Within the bulb were metal sculptures coated with phosphors. These phosphors fluoresced when excited by glow discharge. One such bulb is on display at the MoMA in NYC as part of a Dan Flavin artwork
