Who tried 999 times?
The famous story goes, Edison failed to refine the light bulb (one of the few creations he merely refined but did not invent) so many times it took him 10,000 attempts to perfect.

How long did Thomas Edison’s light bulb burn?
One year later in October 1879 Edison successfully tested a filament that burned for 13.5 hours. Continuing to improve his design, by November 1879, he filed for a U.S. patent for an electric lamp using “a carbon filament or strip coiled and connected … to platina contact wires”.
What is the oldest bulb in the world?
the Centennial Light
The world’s longest-lasting light bulb is the Centennial Light located at 4550 East Avenue, Livermore, California. It is maintained by the Livermore-Pleasanton Fire Department. The fire department claims that the bulb is at least 121 years old (installed 1901) and has only been turned off a handful of times.
What did Thomas Edison do for the light bulb?
Edison will forever be remembered for his contributions to the incandescent light bulb. Even though he didn’t dream up the first light bulb ever crafted, and technology continues to change every day, Edison’s work with light bulbs was a spark of brilliance on the timeline of invention.
What is the patent number for the Edison light bulb?
Patent number 223,898 was given to Edison’s electric lamp. The Edison lamp from our Attic is dated January 27, 1880. It is a product of the continued improvements Edison made to the 1879 bulb.
