“Squirrel Cage” Light Bulb is reminiscent of the early 20th century resembling original Edison light bulbs. Although vintage in appearance these bulbs are used in modern and industrial lighting. Filaments are strung up and down around a glass column to create the cage inside the bulb. When lit, filaments produce a vivid, art-like form. The very visual nature of these “squirrel cage” light bulbs complements modern, mid-century and historic lighting.
