bulb journey

The journey that started with filament electric bulbs has today moved to smart bulb wireless-connected bulbs (which operate on voice commands). The filament bulb was invented in 1879. These bulbs used to last for 13.5 hours. These bulbs are still used in some places today. Here we will tell you how much technology has changed in the world of bulbs. Bulbs that operate with a knock have now started working on voice commands and gestures.

normal light bulb

These are traditional bulbs that use carbon or tungsten filament. These are cheap and easily available, but their durability is a little less.

The bulb made by Edison's hands is still burning today

Edison did thousands of experiments to discover the filament, so that he could get a stable filament. Most of Edison's experiments involved carbon containing filament. In 1880, Edison was granted patent number 223,898 for the electric lamp. During this time, a bulb made by Edison's hand was installed in California. According to reports, this bulb has been burning for many years.

The name of this bulb is Centennial, it was lit for the first time in 1901. At that time this bulb was of 60 watts. After this, its output kept decreasing year after year. In the year 2021, the light of this bulb was reduced to 4 watts.
