The Edison Labs in Menlo Park, New Jersey, is where hundreds of filaments were tested before Edison rolled out the tungsten filament light bulb.Thomas Edison, in his Ohio laboratory.Wrong I'm afraid, Swan invented it 10 years before Edison in Britain.CommentUnfortunately, Swan (and Davey, before him) didn't patent his invention and, so, credit must go to Edison who not only took out the patent on the incandescent lamp but also found a way of significantly improving the life of the lamps' filaments.
