Centennial Light- The story of the world's longest lighting light bulb.

World's longest lighting light bulb

The world's longest-lasting light bulb is known as the Centennial Light, located in Livermore, California. It has been burning continuously since 1901, which makes it more than 120 years old as of my knowledge cutoff in 2021. The bulb was originally a 60-watt bulb manufactured by Shelby Electric Company and was first installed at the fire station in Livermore.

The Centennial Light has been recognized by Guinness World Records as the world's longest-lasting light bulb, and it has become a popular tourist attraction. It has survived numerous power outages, earthquakes, and even a move to a new fire station in 1976. The bulb is now connected to a backup generator to ensure it never goes out.

The secret to the Centennial Light's longevity is its low wattage and the fact that it was made with a carbon filament, which is more durable than modern tungsten filaments. Despite its age, the bulb still shines at about four watts, which is enough to light up the fire station's hose cart room.
