We all know that there are normal things and there are things-centenarians. Surely everyone have such items such as lighter, which is inexplicably not running out of gas, push-button phone "first", which is still included or kettle, inherited from her grandmother. These things include the light bulb filament, which operates in the premises of the fire station in Livermore, California, United States for 120 years.
Light from Livermore received its own name Livermore's Centennial Light (Lawrence Livermore centennial light bulb) were screwed into the cartridge in 1901 and is still in working condition. Most likely, it had a capacity of 30 or 60 watt, but now it hardly produces and 5. The light is very dim, which is not surprising, because, according to the Guinness Book of records is the oldest working light bulb on the planet.

However, this was not her fault, but because of the outside interference. Bulb life of Livermore is not the most eventful, but in fairness, it should be noted and interruptions in its work.
So the light bulb went out in 1903, as it was transferred to the new location. The next interruption in its work was already in 1937, when in Boxing, where she worked, made repairs. The light fixture was then disabled for the whole week. In 1976 the bulb has experienced a move to another building, and it was already a "celebrity" and in a way it was accompanied by a policeman. Yes, she was turned off then on for 22 minutes.
20 may 2013 failure occurred in the network and the uninterruptible power supply has failed. Then the bulb is not burned for at least 9 hours. Said to have been in her long life and other trips, especially in the first half of the 20th century, but they had not been fixed.
