The Centennial Light Bulb in Livermore has been burning since 1901. It is the longest lasting light bulb recognized by Ripley’s and the Guinness Book of World Records.
To ensure it is still burning you can see it on the bulbcam: https://www.centennialbulb.org/cam.htm
It is updated every 30 seconds. While it only uses 4 Watts it is more a glow than a bright site.
You can also visit the fire station where the light bulb is hanging from the ceiling. If a fireman is on hand they are happy to show off this curiosity. Plus there are a few historical fire fighting items on display. Best time to visit, according to the website, is between 10 am and 11:30 am or 3 pm to 5 pm. 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. The fire station is located at 4550 East Avenue in Livermore.
In these ever changing times, continuation is comforting. I visited this site before the pandemic.
Do you have a constant that gives you comfort?
