What is the longest a light bulb has lasted?
The world’s longest-lasting light bulb has been burning for nearly 120 years.

| Incandescent | 750-2,000 hours |
|---|---|
| Plug-in | 10,000-20,000 hours |
| Screw-based | 8,000-10,000 hours |

Who invented the longest-lasting light bulb?
Donated to Livermore’s fire department in 1901, the Centennial Light was made by the defunct Shelby Electric Company in Shelby, Ohio, in the late 1800s. Documents suggest its inventor, Adolphe Chaillet, hoped to create a more efficient, long-lasting bulb.
Why do light bulbs not last long?
Turning a light bulb on sends a jolt of electricity through the filaments, which is more likely to break it than a continued current — that’s why light bulbs often burn out as you turn them on. If you turn lights on and off frequently, you’re likely reducing the lifespan of the bulb.
Who invented the longer lasting light bulb?
Latimer made a major contribution to the development of electric lighting by inventing a longer-lasting filament. But he did not invent the lightbulb. Thomas Edison is regularly identified as the inventor, though that claim is itself often challenged.

Can lightbulbs last forever?
Typically (depending on use), incandescent bulbs will last for about 2,000 hours — that’s usually less than a year if turned on 6-hours a day. The main reason is that the filament in regular bulbs is made of tungsten rather than carbon, as in the “Centennial Bulb”.
Can you make a light bulb last forever?
Given the amount of money you are likely to spend on replacing spent lightbulbs every year, you might be wondering if there are any that could, theoretically, last nearly forever. As it turns out, there actually is. Called the Centennial Light, this is the world’s longest-lasting lightbulb.
Where is the longest burning light bulb?
The Centennial Light is the world’s longest-lasting light bulb, burning since 1901, and almost never switched off. 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 ,…
How old is the oldest burning light bulb?
World’s Longest Burning Light Bulb is 116 Years Old. It’s a fact: the world’s longest burning light bulb is 116 years old, almost 117 years old if it makes it into 2018.
What is the oldest working light bulb?
The Eternal Light is currently 109 years old and was first turned on in September 21, 1908 by Barry Burke, a stage hand at the Byers Opera House. Before the Eternal Light lost the title in the 1970s to the Centennial Light, it was the oldest burning light bulb in the world according to Guinness World Records.
How long do incandescent light bulbs last?
Incandescent light bulbs typically have a lifespan of around 900 hours—a lifespan that translates to about five hours per day for six months before the bulb burns out.
