This style bulb was most commonly produced by the Aerolux Light Corporation in their New York City factory between the 1930s and 1970s. The variety of bulb was called a "gas discharge bulb," referencing its containment of either or both neon or argon gas. Each bulb would contain a representational metal sculpture, in place of a filament, most famously depicting a rose, although bulbs with other flowers, holiday and religious motifs, vignettes and texts were also produced. Each metal sculpture was coated with phosphors, causing it to glow when it interacted with the gasses inside. These bulbs depicting signs of the zodiac were likely produced in the 1970s and are N.O.S. (new old stock) and are unused. Please note that they may take a while to heat up and also may have phosphorus dust inside from age, which will glow throughout the bulb. They should be used in a standard american socket.
