The latest episode of 99% Invisible tells the story of one light bulb in Fire Station #6 in Livermore, which has been burning consistently for the past 113 years. As proof of its continued longevity, there's even a webcam trained on it. And in 2001, Livermore residents had a hundredth birthday party for it. Designed by Adolphe Chaillet, the bulb was engineered to accept more power than competing bulbs at the time—others would explode as Chaillet dialed up the power, but not this model—though its persistence continues to befuddle.
