Quad Loop Filament A23 Nostalgic Edison Light Bulb. Our vintage quad-loop reproduction bulb is a masterpiece. Featuring a slight amber-tinted glass with a tip on top of the bulb typical of early 1900's manufacturing enhances the antique look of this bulb. The quad looped tungsten filament creates a warm welcoming glow that should be enjoyed behind a clear shade or a bare socket.
A23 stands for the shape and size of the bulb (glass). It is the bigger of the 3 sizes. A19, A21, and A23
I found a similar product in a box store, and while I loved them, they were way too expensive. These bulbs are just as beautiful ~ and have the perfect vintage glow! I'll definitely come back for any future lighting products. Also, quick delivery! Thanks & Happy Holidays!
