• Although he tries experimenting with filaments made from different materials, like paper, linen threads and wood splints.
• Electric bulbs with carbon were first exhibited by Edison in 1879.

• In 1904 a tungsten filament was found more efficient and durable than the carbonised bamboo filament that Edison had used previously.
• When a neutral gas was introduced into the glass envelope it improved the brightness and the durability of the bulb.
• In order to produce more light, the bulbs required the use of long filaments, until the wound tungsten filaments were found efficient
