Two lesser-known inventors, Humphrey Davy and Joseph Swan (who won a patent lawsuit against Edison), both developed working electric lights well before Edison.

If Edison did not invent the tungsten bulb, we would have keeping the oil lamps or we were using bulbs found by the person above and will be having a lots of waste bulbs in our houses.

Tungsten has high boiling point and melting point so it will last long

If we don't have tungsten bulb there would be more expenditure only for bulb
