In the early days of electrical lighting inventors such as Thomas Edison tested and retested as they searched for long-burning filaments. In 1890 the filament choice was carbonized cotton. Globe Electric’s bulbs have a tungsten filament which is used to reproduce the single hairpin loop of a vintage design. The shapely Granada bulb is a prestigious accent for any decor. Simply position it within a clear shade or exposed socket to enjoy its shape and ambient glow. Create the perfect ambiance for any mood by dimming it to your desired strength. This Edison inspired bulb is a Steampunk favorite with its glowing cage-shaped filament surrounding a central glass support. Crafted to preserve the look of early 20th-century lighting Globe Electric’s Incandescent vintage designer GRANADA 40w amber finish 120v medium base bulb is the perfect way to brighten a room.
