We know that the lifespan of an ordinary light bulb is generally 1,000 hours, and a carbon filament light bulb from the Fire Brigade in Livermore, California, is now 115 years old. Since the installation in 1901, except for a brief shutdown due to the fire brigade’s relocation and line failure, the rest of the time has not been extinguished for a second.
A few days ago, Guinness World Records has confirmed that it is "the world's oldest light bulb." As for the "secret to longevity" of this longevity bulb, many people speculate that because it never switches on and off, the filament has a long life.
The designer of the light bulb was Adolphe A. Chaillet of the Shelby Electric Company (Shelby Electric Company), who had competed with Edison, the inventor of the modern light bulb, to see who could make the best light bulb.
This old bulb also has its own Facebook page (//www.facebook.com/livermorecentenniallightbulb) and official website (//www.centennialbulb.org/). If you don’t have a VPN, you can at least use a webcam. , Pay tribute to this legend.
