The Chronicle of The Light Bulb

No one can discredit one of the most valuable breakthroughs in human history, the electric light bulb. It came off as a source for lighting by means of electric current late in the 18th century. This turned the tides for gas lamps and the unconventional fire torch. But as it has immensely benefited the human race at times of dark, its technology has reached its era of propriety.


Until the 1900s the halogen bulb thrived and even had some upgrades allowing it to glow even brighter. But the cost was not reciprocal to the light it produced. During the 1950s research began on energy efficient lighting and a major find took the headlines. A genius successfully passed electric current through vacuumed glass tube, illuminating the device. This was not only a light that surpassed the incandescent bulb but took it by the throat when it came to its energy cost. This was the first invention in terms of energy efficient lighting and many seemed pleased—but not Edward Hammer though. In 1976, General electric with the help of Mr. Edward designed the next level of fluorescent tube. By bending it into spirals and adding mercury to its insides, Edward created a light so bright and efficient that its prime is still not over to this day. Hence the first compact fluorescent lamp or CFL was baptized by General Electric in 1976.  

This however did not stop other bright minds from slaving electricity to a higher extent. Newer mods on CFL were still coming out with slightly better results, but the time and funding this plateau consumed was ungratifying. So it was taken to oath by the pioneers that a newer technology must be developed, but had no idea what was in store for them. Even though light emitting diodes or LEDs had been going since 1962, their uses were limited due to their primitive designs. But it wasn’t till the late 1990s when the LED made its debut in the form of domestic and commercial lighting. The device worked with the superiority of electrons filling the holes once the semiconductor is charged, initiating the flow and producing light in the form of photons.

Once its design and engineering received top of the class tweaking with a few other upgrades, the LED was the Christ to homeowners and businessmen scorched under the burning filament of the ungrateful halogen bulb. It gave better and brighter light at only 10% the cost of what an incandescent bulb would in a year. This revolution has made its mark and with much less carbon signature and more saving on the bill, the LED light is making history.
