Centennial Bulb – Livermore, California - Atlas Obscura

Centennial Bulb

Fire Station 6

The longest burning light bulb in the world. 


With only a few brief exceptions, the light bulb hanging in Fire Station 6 in Livermore, California, has burned continuously for 117 straight years.

It wasn’t until 1972 that a local reporter first took note of the unusually long-lived bulb. News of its existence spread, and the bulb soon appeared on On the Road with Charles Kuralt and in the Guinness Book of World Records and Ripley’s Believe It or Not.

The bulb has been moved a few times, once unceremoniously (it was only two years old) in 1903, and then with much more pomp in 1976 when it was transferred with a full police and fire truck escort to its present site. The bulb is now cared for by the Centennial Light Bulb Committee. 

You can check if the bulb is still going on a live camera feed on the Centennial Bulb’s website.

Know Before You Go

You can visit the bulb depending on the availability of the firemen on hand. Go to the rear of the station and ring the bell. If they are in someone will answer the door. Otherwise you can see the bulb if you look through the window up on the top of the wall to your left. To contact them directly you may call the LPFD at (925) 454-2361.
