Our 30W Squirrel-cage Tungsten Filament Bulb is a throwback to the early 1900s, when the bright new concept resulted in lighting designs like semi-indirect bowl chandeliers.

Tip: Install upright or upside down. Bulb can fail if pointed horizontally or at an angle.

Carbon-filament light bulbs debuted in the 1890s and lit the way until 1912, when bright and powerful tungsten-filament bulbs transformed the industry.

Painted bulbs, introduced in the 1920s, added a decorative touch to tungsten bulbs and the exposed-bulb fixtures popular at the time.
