I had a question about light bulbs. I thought that a light bulb burned out because it deteriorated due to all the friction and heat. My older brother said that the word deteriorate didn't sound right and didn't make a lot of sense for what was happening in a light bulb. So, I asked if the gas in the light bulb that lets you see the light from the wire better was burned up and he didn't know. I then realized I wasn't actually shore why a light bulb burned out.

This video turned to be more on the manufacturing lightbulbs and a light bulb conspiracy I found interesting, but couldn't find much supporting or contradicting evidence for. it did say that heat fluctuation was one of the ways a light bulb could go out. 

Deteriorate definition:

to cause something to break down or disintegrate.

After a while I concluded that they do degrade over time, but different light bulbs had different ways of disintegrating or what was most common for those types.

so, power lines were meant to be below ground, not above. 

In summary of those videos, Thomas Edison is not the one who discovered the light bulb but did make it more reliable and be able to be used in a home. He made his own generator, ways of transferring electricity, and greatly improved the lightbulb structure. there are two metal wires in a light bulb that connect to a filament. when the filament is exposed to electricity (the movement of electrons) it glows as it heats up (because of friction). the metal prongs are often a more heat resistant material like tungsten or molybdenum and are called lead- in wire or rods, the gas in the bulb is also often argon, halogen, or something similar.

When things get hot, they tend to light on fire. To prevent this the filament was encases in a glass bubble and all of the air was pulled out of the bubble. Glass is see-through and hard so you can see the light through it, it can be sealed by melting, and it won't let air through. fire cannot burn without air so to get the glowing effect without fire you take the air away.

How was the air taken and kept out of the light bulb before and during sealing it?

What light bulb filament lasts the longest?

The longest burning lightbulb has been burning since 1901 and is still burning today, the filament is made of carbon about the size of a hair. it is almost never turned off but has dimmed over the years. it was originally a 60-wat light bulb but now produces 4-wats, it is used as a night light at a fire department. - It was donated because the company was going out of business and was about to be sold.

back then the light bulbs were not made with gas in them but had a vacuum, so the inside was devoid of air. the glass was also hand blown. 

nowadays most light bulbs are made with gas in them, this is because people started swapping out carbon for tungsten filaments and it was found that some gasses could help prolong the life of the tungsten. 

Krypton- and xenon-filled light bulbs do not burn as hot as argon-filled ones.

Halogen light bulbs last longer than the other types of gas-filled bulbs, with a lifespan of up to three years or about 2,500 hours of use.
