Oldest Light Bulb, Livermore

About Oldest Light Bulb

The Centennial Bulb is the world's longest-burning light bulb, housed at Fire Station #6 in Livermore, California. Visitors observe the historic Shelby bulb, which has remained illuminated for over 120 years, through the station's front window or by requesting entry when firefighters are available. The attraction features a live Bulb-Cam that streams continuous video of the bulb, allowing guests to watch it before visiting. On-site, visitors can view a multi-bulb display lit up during their visit and examine a 100-year-old Shelby bulb up close. The facility maintains galleries and photograph collections documenting the bulb's history, including images from celebration events. The location also provides access to video documentation and articles spanning decades of recognition and scientific interest. Families and history enthusiasts find this modest but unique attraction at a working fire station.
