Capture the beauty of early electric lighting with the Victorian Quad Loop A21 Vintage Edison Light Bulb. Inspired by antique bulbs from the early 1900s, this 40-watt incandescent light bulb features a distinctive quad-loop tungsten filament, clear glass construction, and a decorative glass tip that celebrates the craftsmanship of vintage lighting.
The intricate quad-loop filament produces a soft, warm amber glow at 2200K, delivering 120 lumens of decorative illumination. Rather than overwhelming a room with brightness, this bulb creates an inviting atmosphere while allowing its exposed filament to become part of the overall design.
With its A21 glass shape, this Victorian-style bulb offers a larger appearance than the A19 version without reaching the size of the A23. Measuring 5 inches long and 2.75 inches in diameter, it is an excellent choice for exposed-bulb pendants, clear glass shades, and decorative fixtures where the bulb itself is meant to be seen.
The standard E26 medium screw base fits compatible North American light fixtures, while its dimmable incandescent design lets you adjust the lighting atmosphere using a compatible dimmer.
