Satin string bulbs simulate the feel and charm of an old style gas light. The unique, silk-like threading wraps around the bulb and distorts the image of the filament into an elongated glow. Perfect for use in outdoor lanterns and exposed bulb chandeliers. The Satco S3403 satin string bulb is a great option for antique restorations. The candelabra base on this bulb fits into most chandeliers and other candelabra sockets.
