Centennial light 113 years old still lighting in Livermore fire station |
Just heard about a light bulb which was bought in 1903 and is working after all these years barring a few instances when it went off due to wiring faults, power failure and whilst the time the place it was placed, i.e. a fire station, moved premises.
It is a hand-blown common 60W bulb made from carbon filament in the 1890s, donated to a fire brigade when light technology was in its infancy. It was a sort of community service for the voluntary firemen to get ready to rush to their job. The bulb kept on burning over the years, seeing many transformations in mankind. It saw the Wright brothers fly for the first time, two World Wars and survived two transfer of premises! The company which manufactured these type of long lasting bulbs, Shelby Electric Company, later went bust.
In the 1920's, at a time of economic awakening after the devastating effects of World War 1, a bulb cartel mooted a movement referred to 'Planned Obsolescence'. They grappled the idea that 'a product that refuses to wear out is a tragedy of business'. Hence, there was a conspiracy to shorten lifespans of products. This, with the lure of Edward Bernace's use of psychological marketing, generated sales and boosted the economy. Pretty soon, carbon filaments were replaced with tungsten and bulb's life span reduced from a lifetime or more to 2500 hours to 1000 hours.
Interestingly, the light of the technologically advanced webcam which was set up to watch the Centennial Bulb when it became a national heritage, had to be replaced a couple of times. It continues performing its duty, albeit at a lesser glow akin to a 4W nightlight.
