Summary
A presenter described the bulb’s origin in a Livermore fire station and its unexplained longevity, and announced a public celebration at the station on June 6, 2026, at 10 a.m.; the speaker said proceeds from a self-published book will benefit a local firefighter foundation.
Unidentified Speaker, identified only as the presenter, told attendees that the Centennial Light Bulb — installed in a fire station on 2nd Street in Livermore — will be honored with a public celebration on June 6, 2026, at 10 a.m. "People ask me what is the Centennial light bulb," the presenter said, explaining that the bulb was purchased from Shelby Electric in Shelby, Ohio and installed to provide a constant light so firefighters could find equipment at night.
The presenter described the bulb’s longevity as a subject of scientific curiosity. "This one never gets turned off," he said, and recounted that physicists from around Livermore lab and elsewhere have studied the fixture without identifying a clear reason for its unusually long life. The presenter repeated Shelby Electric’s historical claim that the manufacturer used a distinctive carbon-filament process that may help explain the bulb’s durability, but said modern scientists have not replicated or confirmed that explanation.
The talk placed the bulb’s service in historical context, noting it has been in place through World War I and World War II and remains a continuously lit fixture in the station. The presenter announced the June 6 event as part of Livermore’s larger sesquicentennial observances, saying the celebration at the fire station will include a birthday cake, antique fire apparatus, a barbecue and an award for the person who traveled the farthest to attend.
The presenter also discussed information resources and fundraising tied to the event. He said a book he produced in 2015 is available on Blurb.com and that copies, along with other related books, will be sold at the June 6 celebration. According to the presenter, proceeds from sales of his book will go to a local firefighter charitable foundation; the presenter expressed plans to make the book available on Amazon in the future.
The presenter used the words "125 years of illumination" when describing the anniversary but also made a separate reference to a "120 birthday" during the same remarks; the recording contains both figures. The event time and date given by the presenter was June 6, 2026, at 10 a.m. For additional background, the presenter suggested searching the terms "Centennial bulb" or "Centennial light bulb," and noted there are numerous online items and YouTube videos documenting similar bulbs.
The presenter did not provide a personal name during the recorded remarks. Dennis Bernal was named in the presentation as the person who owned the town power and water company when the bulb was purchased from Shelby Electric.
