Worlds Oldest Lightbulb

Described in the Guinness Book of World Record's as the oldest light bulb in the world, this bulb just celebrated its 110th birthday on June 18,2011. The Livermore, Ca. Station 6 firehouse is home to this record
setting light bulb.

The 60 watt light bulb that just won't quit was installed in 1901 and has burned continuously, except for a few blackouts and some outlet moves, at it's home home in the Livermore Ca., fire station. It's used as a nightlight over the firetrucks and is never turned off.

Even when it fails, it will still have been the world's oldest functioning lightbulb. Until another outlasts it. I'll not be waiting with bated breath for that one though.

Might possibly be that it's run at a mere 6.7% of rated power has something to do with it. I wouldn't be madly impressed by a bulb lasting 11 yrs at 67% rated power or even 7.3 yrs at 100%.

Overclocking to say 70W might have a slightly different effect on its lifespan. If its webcam is online, maybe its PSU is too.... :twisted:

It is run on reduced voltage :) about 50 % IIRC heard a few interviews with the firehall lads over the years.

Enjoy the Choice :)

Well, the linked article said it was run at 4W. 50% of rated power would be 30W - or, at 50% rated voltage and ignoring change of resistance with temperature, that would be 15W.

:D I loved the use of the verb 'overclocking' in the context of a lightbulb :D
