A Light Bulb Defies Time.. A Bright Flame for Over a Century Becomes a Tourist Attraction in California

In a striking phenomenon that combines history and technology, a small electric light bulb has been illuminating a fire station in Livermore, California, for over 120 years, making it one of the longest-working bulbs in the world, and it is set to celebrate 125 years of operation this year.

The bulb has received recognition from the Guinness World Records and has turned into an unconventional tourist destination in Northern California, despite its simplicity and its current reliance on an electrical capacity of only 4 watts.

Throughout its long history, the bulb has only been turned off a limited number of times, most of which occurred during the relocation of the fire station, with a single recorded outage in 2013 due to the generator battery running out.

The bulb attracts visitors from around the world, has been mentioned in several children's books, and has become part of the daily life of the city's fire crew.

The secret to its longevity lies in its unique design; it was made in 1897 by French inventor Adolphe Chaillet for the "Shelby Electric" company in Ohio, using a treated cellulose filament that turned into carbon, giving it exceptional durability and the ability to operate for long periods without damage.

The company's bulbs underwent durability tests compared to competitors' products and succeeded in outperforming them, making Chaillet's design one of the most efficient and longest-lasting bulbs on the market at that time.

Despite the cessation of production of "Shelby" bulbs in 1912 after "General Electric" acquired the company, this bulb has continued to operate since it arrived in Livermore in 1901, when it was donated by Dennis Bernal to the local fire station.

The bulb accompanied the station's move to its new building in 1906, where it was reactivated immediately after the equipment was transferred. In 1971, an investigation by the "Livermore Herald News" highlighted its story, contributing to its global fame, before Guinness later confirmed its record.
