The world's longest lasting light bulb is at least 110 years old and is still glowing.

The Centennial Light is the world's longest-lasting light bulb. It is at 4550 East Avenue, Livermore, California, and maintained by the Livermore-Pleasanton Fire Department. The fire department says that the bulb is at least 110 years old and has been turned off only a handful of times. Due to its longevity, the bulb has been noted by The Guinness Book of World Records, Ripley's Believe It or Not!, and General Electric. It is often cited as evidence for the existence of planned obsolescence in later-produced light bulbs.
