– The light bulb was invented by Thomas Edison in 1879.
– The light bulb was the first commercially successful electric light.
– The light bulb is a type of incandescent light.
– Incandescent lights are lights that produce light by heating a filament until it glows.
– The light bulb was originally made of carbon.
– The light bulb was later made of tungsten.
– Tungsten is a metal that is resistant to heat and wear.
– The light bulb is usually filled with argon gas.
– Argon is a gas that is used to prevent the filament from burning out.

How long a light bulb lasts depends on the type of light bulb and the amount of use. Incandescent light bulbs usually last around 1,000 hours. CFL light bulbs usually last around 10,000 hours. LED light bulbs usually last around 50,000 hours.
Who made the first light bulb?
The first light bulb was created by Thomas Edison in 1879. He was an inventor who was known for his work on the light bulb, the phonograph, and the electric railway.
Is Edison’s first light bulb still burning?
On October 21, 1879, Thomas Edison completed his work on the first incandescent light bulb. This event is considered to be the beginning of the modern age of electricity. The bulb was made of a carbon filament inside a glass enclosure. It glowed when a current was applied to it.
Edison’s first light bulb was not a commercial success. It burned out quickly and was not very bright. However, Edison continued to work on the light bulb and eventually developed a longer-lasting and brighter bulb.
The first incandescent light bulb is still burning today. It is on display at the Henry Ford Museum in Dearborn, Michigan.
