Light bulb shining after an incredible 130 years

While most modern light bulbs barely last a year, a bulb in UK is still glowing after an amazing 130 years, making it one of the oldest in the world.

The bulb, dating from 1883, was clearly built to last with six internal filaments which wobble when in use.

It continued to give good service throughout two world wars, shining well into the new millennium, the 'Daily Mail' reported.

The bulb first belonged to the late Florence Crook who once took it to school to dazzle her classmates. It then passed down to her son Kenneth, in Morecambe, Lancshire and is still in use by his widow Beth, 79, at their home.

"It's a real talking point. There is no substitute for craftsmanship. The new eco bulbs take all week to warm up and hardly give off any light," Beth told the 'Daily Express'.

The bulb, marked EDISWAN, has the number 200-32:B.56 on the glass. The UK's previously oldest working bulb surfaced after 113 years continuous use in Margate, Kent, in 2008.

Ediswan was a collaboration between the British Physicist Sir Joseph Swan and US scientist Thomas Alva Edison, both of whom are independently credited with the invention of the light bulb in 1879.

Swan's break through was to use a vacuum which meant there was very little oxygen inside the bulb so the filament to glow white-hot without catching fire.

It rolled of the production line as Queen Victoria was beginning her 64th year on the throne and William Gladstone was the UK Prime Minister, the report said.

According to the Guinness Book of Records the world's oldest light bulb in continuous use has been burning for 109 years and holds pride of place in Fire Station 6, in Livermore, northern California.
