It was a lamp powered by electricity. The principle remains familiar today: a current passed through a filament enclosed in a glass bulb causes the filament to become incandescent. Less than 25 years after 'the Wizard of Menlo Park' secured his patent, the Shelby Electric Company made a carbon-filament lamp with a hand-blown bulb. To be more accurate, they made thousands, but one in particular found its way to the hose-cart house of the fire department of Livermore, California. It was first switched on in the summer of 1901. The same bulb is still working more than a hundred years later1. The claim of World's Oldest Lightbulb has been verified by the Guinness Book of Records, and is said to be ratified by newspaper records and a technical audit by General Electric.[img]http://i890.photobucket.com/albums/ac110/preeto_f151/ligthbulb.gif[/img]The 'Livermore Light' has burned continuously for most of its life, putting out a steady four watts or thereabouts. It originally served as a nightlight, illuminating the area where the fire-tenders were housed, but has long since progressed to the status of revered curiosity. It has been moved without mishap a couple of times over the years, most recently in 1976 to the current site of the station at 4550 East Avenue. The bulb's hundredth birthday was celebrated on 8 June, 2001 with a community barbecue. Three bands provided live music: one contemporary, another playing 1950s tunes and the third performing in the style of the first years of the 20th Century. The Livermore Light has its own website and is open to visits by the public.

The Livermore-Pleasanton Fire Department has no plans to replace their celebrated lightbulb. Although its usefulness is minimal, it's now too big an attraction to contemplate disposal. When it does eventually succumb, it certainly won't be thrown away either. Ripley's museum is first in line to receive and preserve the corporeal remains of the longest-lived lightbulb in history.
