Longest burning light bulb

According to Official Guinness Records,

The Livermore Centennial Light Bulb, at Firestation #6, Livermore, California, USA, has been burning since it was installed in 1901. As of 2010, the hand-blown bulb has operated at about 4 watts, and has been left on 24 hours a day in order to provide night illumination of the fire engines.
There has only been one break in its operation when it was removed from one fire station and fitted in another.Photograph: Richard JonesCentury of Light from Richard Jones on Vimeo.
