125 Years Strong: The Light That Never Quits

Inside a California fire station, a lightbulb has been burning for more than a century and is set to reach its 125th anniversary this summer. The Centennial Light, located at Fire Station No. 6 in Livermore, has been glowing almost continuously since 1901. It holds the Guinness World Records title for the longest-burning lightbulb.

This unique fixture, currently emitting only four watts, has seen minimal interruptions, primarily during firehouse relocations. Its most recent brief outage in 2013 was due to a generator battery issue, not the bulb itself. Visitors from around the globe have been drawn to this incandescent wonder.
