The light bulb which led to him being famous. It was a huge success because now he’s world famous. Joseph made good use of his time with Mawsons where he experimented with ways of extending the life of an electrically heated filament. During the first half of the 1870’s Crooke’s work with more efficient vacuum pumps and McLeod’s gauge to measure the vacuum produced gave Swan the impetus to experiment with the heating of a filament in a vacuum. With a carbon filament sealed into a vacuum bulb he was able to produce an incandescent light without the oxidation that had limited the filament’s life up to that point. He made further developments in filament materials to enable the production of the first successful incandescent light bulbs
