Flower Light Bulbs – Forgotten Wonders of the Mid 1900s

Most of us don’t pay much attention to light bulbs. They play a very important role in our lives, but when it comes to aesthetics, most of them are nothing special. But there was once a company that produced the most amazing flower light bulbs, and luckily some of its creations are still around today.

Aerolux Lighting Corporation was an artistic light bulb manufacturer that operated from the 1930s through the 1970s. The company made beautiful gas-discharge light-bulbs in various shapes, from cartoon characters and animals, to religious symbols and popular emblems. But their most impressive and popular creations were the flower light bulbs. They not only had these intricate metallic flower sculptures for filaments, but they would also shine in various colors depending on the gases and coatings used. They were really popular back in the day, and looking at the photos below, it’s easy to see why.

According to Wikipedia, “Aerolux gas discharge light bulbs contained low pressure gas, either neon or argon, or a mixture of the two. Also within the bulb were metal sculptures coated with phosphors. These phosphors fluoresced when excited by glow discharge. Because glow discharge occurs readily at 110-120 volts AC, one could use these bulbs in standard household lamps in the United States.”

Jonas Clark-Elliott adds that “The red bulbs are filled with neon gas, the pink bulbs with a neon-argon mix, and the purple/violet bulbs with argon gas. The green color (as was used for grass, accents in advertising bulbs or leaves in the flower and bouquet bulbs) was produced by coating the metal with barium, which responded to the wavelength of light given off by the ionized gas.”

Because the phosphors used in Aerolux bulbs were somewhat brittle, they had to be handled with care. Shaking or jarring the bulbs could cause flaking and the migration of the phosphors to other parts of the sculpture or to the inner glass of the bulb. They consumed about 3-5 watts of power, and had a  high yield of light produced versus electricity consumed.
