The World's Longest Running Light Bulb

Incredibly, there is a light bulb in Livermore, California that has been burning since 1901. The aptly named Centennial Light serves as a nightlight for the firetrucks of the Livermore Fire Department. There is a live webcam on the official website of the Centennial Light. It has been declared the oldest known working lightbulb by Guinness Book of World Records.

The Shelby Electric Company made the bulb. It was handblown and then outfitted with a carbon filament. It has about 4 watts of light.

If you happen to be in Livermore, California then you can stop in and visit the bulb, depending on the availability of the firemen. If you go to the rear of the station and ring a bell then you can ask them to let you in. Otherwise, according to their site, "you can see the bulb if you look through the window up on the top of the wall to your left." The photo below is courtesy of the Centennial Light Bulb Committee. There are more of photos to be found here.

  • That's pretty cool i guess. that's about a hundred and eight years ago. that might be a good speech for someone to make one day.

  • I haven't heard this new before,Its awesome and record.World's Long lasting light bulb since 1901, Its great to be still burning and its been 108 years and still counting.Manufacturer can be awarded with Genius Book record.

  • Ronald - That is pretty crazy for a bulb to last that long; then again, it's only putting out less than 4 watts of light. The second longest bulbs supposedly dates from 1908. Wikipedia has a page devoted to the top long-lasting bulbs if you'd like to learn more: en.wikipedia.org/.../Longest-lasting_light_bulbs

  • Energy efficient light bulbs are the easiest first step  consumers and businesses can take towards reducing their energy consumption.  Products have gotten light years better in the past few years and, in my eyes, indisputably  better for 99% of applications. Both CFL and LED light bulbs run much cooler  than incandescent bulbs, use energy much more efficiently, and do offer saving  on your electricity bill. I am a vendor of energy efficient bulbs, so perhaps I  am a bit biased, but I don't know why everyone doesn't switch today.

  • I have a light bulb in my garage that hasn't had to be replaced for the 19 years I have lived here. Wish they made light bulbs like that nowadays. I also changed a Phillips light bulb in my living room lamp about 3 weeks ago and had to change it again this week. That is the shortest lasting bulb I've ever had.
