Globe Electric’s 2.5W (40W equivalent) Vintage Candelabra LED Bulb. 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. Position it within a clear shade or exposed socket to enjoy its shape and ambient glow. 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. Please note, these bulbs are not as bright as modern bulbs of the same wattage and are recommended for exposed socket fixtures. These bulbs can be dimmed.
