This product is the perfect bulb to use with open socket fixtures. The standard E26 base fits in most household items so you can use it in any light you want to provide a beautiful old-world feel. 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. Our 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 fixture to enjoy its shape and ambient glow. This Edison-inspired bulb is a steampunk favourite with its glowing cage-shaped filament surrounding central glass support. Crafted to preserve the look of early 20th-century lighting. These bulbs can be dimmed and have a lifespan of 3000 hours.
