Detailed explanation-1: -Edison employed a vacuum glass tube around the filament to prevent oxidation, which would damage the filament. By 1880, Edison had come up with a 16-watt bulb that lasted for over 1, 500 hours and patented it (Edison).

Detailed explanation-2: -But it wasn’t until more than a year later, on the morning of October 22 (after working all through the day of October 21, 1879) that Thomas Alva Edison and his team finally “perfected” the incandescent light bulb.

Detailed explanation-3: -On January 27, 1880, Edison received the historic patent embodying the principles of his incandescent lamp that paved the way for the universal domestic use of electric light.

Detailed explanation-4: -By January 1879, at his laboratory in Menlo Park, New Jersey, Edison had built his first high resistance, incandescent electric light. It worked by passing electricity through a thin platinum filament in the glass vacuum bulb, which delayed the filament from melting.
