This 60-watt vintage bulb is our most popular bulb. Measuring 5.5" in length and clear glass finish this Edison ST64 bulb is stunning. The warm amber glow from the hand-wounded tungsten squirrel cage filament ensures the authentic nostalgic color and look. Ideal for use with exposed socket lamps and fixtures with a medium (E26) standard base so the historic filament design could be fully enjoyed. Fully dimmable with all dimmer types and could be used any indoor or outdoor applications.
