The electric bulb was invented by Thomas Alva Edison. But long before Edison, scientists and researchers were looking for electric lamps to replace traditional lamps. It was only in the 19th century that inventors worked hard to find a safe and convenient medium for illumination. Based on all those works, Edison developed a modified form of the light bulb and patented it. There are many types of bulbs available in the market today. There are many companies that give a guarantee of one or two years on their bulbs. However, it is very rare that a bulb burns continuously for two-three years. But today we will tell you about such a bulb, which has been burning continuously for 120 years, not one or two years. This bulb has not fused till date. Not only this, some people have now started considering this bulb as a miracle.
