The Centennial Light is the world’s longest-lasting light bulb, burning since 1901. It is at 4550 East Avenue, Livermore, California, and maintained by the Livermore-Pleasanton Fire Department. Due to its longevity, the bulb has been noted by The Guinness Book of World Records made by the inventor, Thomas Edison.
the average incandescent light bulb (that is, a bulb heated with a wire filament) has a lifespan of about 1,000 to 2,000 hours. Light emitting diode (LED) bulbs, which are increasingly replacing incandescent bulbs, are said to last between 25,000 and 50,000 hours — an incredible bump.
But dangling from the ceiling of a California firehouse is a bulb that’s burned for 989,000 hours — nearly 113 years. Since its first installation in 1901, it hasn’t been turned off or burnt, has outlived every firefighter from the era, and has been proclaimed the “Eternal Light” by General Electric experts and physicists around the world.
I first got to know about this bulb 3-4 years ago.
There is something fishy going on there.
