With Thomas Alva Edison's invention of the light bulb, the elements were constructed of Carbon. Newer light bulbs are constructed of Tungsten, which takes much longer to bend into a coil within a coil within a coil, but shines much brighter and lasts for thousands of hours.

Why are light bulbs filled with gases?
the circle ones that are going out known as heat bulbs because the filament inside heats up and only 30% of the energy is light the other is heat the long skinny one have gas that changed into plasma i believe and the plasma glows not making much heat so you can take it out not like the heat bulbs.
How hot do LED light bulbs get?
LED light bulbs normally don't get hot unlike the incandescent ones.
Do laser light shows have light bulbs?
No. They have LASERs. Usually gas ones.
How many lights bulbs are on the Titanic?
There were over 10,000 light bulbs on Titanic.
How does a lightbulb make light?
It depends which type of bulb you mean... The 'energy saver' ones - are miniature fluorescent bulbs - they have a light-emitting coating on the inside, which is 'stimulated' by mercury vapour created when the power flows through it. The older 'pearl' bulbs work by the resistance of a wire filament inside the bulb causing it to glow as it heats up.
What gas is used inside the bulbs?
Assuming the question is referring to incandescent light bulbs (the ones with the glowing filament), Argon is the gas used.Argon is a harmless gas found in air, and is used because it cannot react with the hot filament.
Should you replace filament light bulbs with energy saving bulbs?
Yes, on an attritional basis, as the old ones burn out-
Which light bulbs give off all the colors of visible light?
Incandescent bulbs or if you prefer, plain old fashioned light bulbs, the ones with a filament (the bit of wire inside) that gets very hot and gives off light. They tend to give off a bit more at the red end of the spectrum, particularly the lower power ones but they do give off all the colours. Some run the filament at a sufficiently high temperature to give a pretty balanced white light. Most of the modern energy efficient bulbs give off light at a limited number of frequencies but much more light per watt of power that goes in.
What light bulb uses less amount of energy?
compact flourescent light bulbs (cfl) the swirly ones
When did the light bulb start to change?
In recent years, the light bulb started to change when the newer CFL bulbs came out. The newer bulbs were energy efficient and people were urged to change older incandescent bulbs to the newer ones.
What is difference between regular household light bulbs and led bulbs?
LED light bulbs definitely are more energy efficient than regularly normal light bulbs. Depending on the usage, LED lights can also last maybe twice or three times as much as regular bulbs. LED ones are better.
What should you do to save money on your electric bill?
You can buy the fluorescent light bulbs or tubes. They are the white ones. They use less energy that the yellow bulbs.
