New Delhi: Typically, companies buying any electric bulb offer a guarantee of one year or hardly two to three years on it. It is very rare that a bulb will burn continuously for two-three years, but you will be surprised to know that there is also a bulb in the world, which has been burning continuously for 118 years. These bulbs have not fused till today.
This unique bulb is known as Centennial. This bulb, installed in the firearm office of the city of Livermore, California, was built by the Shelby Electronic Company, which was first lit in 1901. Since then, this bulb has been burning continuously. According to media reports, this bulb was first switched off in the year 1937 to replace the electric wire and it was turned on again after changing the wire. The name of this bulb is recorded in the Guinness Book of World Records. This bulb is monitored with a CCTV camera.
This bulb went off on its own in 2013, when people thought that the bulb might have fused, but when tested, the wire malfunction came out. After this, the wire was replaced again and the bulb again lit up. Running four watt of electricity, this bulb keeps on burning 24 hours throughout the day. In the year 2001, this bulb's 100th birthday was celebrated with pomp, in which a music party was also held.
