A little about it

His experiments involved the fabrication and testing of many different metal filaments, including platinum.Edison then resorted to a carbon-based, high-resistance, filament. One year later in October 1879 Edison successfully tested a filament that burned for 13.5 hours.
The light bulb now is different from the one back in the day.
