Edison light bulb collection to go under the hammer

A COLLECTION of 23 light bulbs used by Thomas Edison to prove he was the inventor of the ground-breaking technology went on display yesterday ahead of their auction.

The bulbs were used in a trial in 1890 when Mr Edison defended his patent for the light bulb.

They were documented at the time of the trial but were presumed lost until 2002, when they were discovered by chance in a US attic, still in their original wooden case.
