This is the case in any bulb that heats a filament. The current flowing through the filament generates heat which radiates photons and produces the light you see.

Is magnesium used in light bulbs?
There is no reason to use magnesium in light bulbs. Magnesium readily and easily catches fire and burns -- white hot.
Is titanium used to make the filaments in light bulbs?
Tungsten is used because it has a high melting point and maintains a high strength at high temperatures - like those required to make it hot enough to give off light as a filament in an electric bulb.
Is a light bulb a kind of lever?
No. A light bulb is a bulb that contains a filament that gets hot when electric current is passed through it.
Is a light bulb filament as hot as lava?
The filament of an incandescent light bulb is actually significantly hotter than lava. Temperatures may exceed 4,000 degrees in some bulbs.
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 is a filament that glows white hot in electric light bulbs?
Tungsten :)
What is the filament that glows white hot in electric light bulbs?
Usually a Tungsten alloy.
How hot do light bulbs get?
hot
How hot do LED light bulbs get?
LED light bulbs normally don't get hot unlike the incandescent ones.
Why are light bulbs so hot when they are turned off?
light bulbs are hot because the coils spread heat around the bulb.
Is it the chemical reactions the reason light bulbs are hot to the touch?
Yes, but its more of the result of the reaction, which is heat and light. More efficient is florescent which produce more light than heat.
What property of column 0 gases makes them suitable for filling electric light bulbs?
Those gases do not react chemically so do not damage a hot filament in a bulb.
What is the common difference between the tube light and CFL bulb?
regular light bulbs have certain elements in them, that when electrified, emit radiation in the infrared. this is why regular bulbs get hot. when we turn on the light we need light, not heat. that's why these are wasteful. they're producing all this stuff we don't need. CFL bulbs have elements that when electrified, emit mainly visible light, what we need. also why they tend to remain cool to the touch.
Is magnesium used in light bulbs?
There is no reason to use magnesium in light bulbs. Magnesium readily and easily catches fire and burns -- white hot.
How is a light bulb like the US government?
1. Like a government, light bulbs can be wasteful. 2. Sometimes, the light bulb just sits there and does nothing. 3. Sometimes light bulbs contribute to hot air. 4. Just like you pay taxes, you have to pay an electric bill to keep the bulb going. 5. Bulbs require electrons and protons, like the government has Democrats and Republicans. 6. People sometimes complain when the light is on, and they complain when there is no light.
Why doesn't a light bulb become hot when lighted?
Lightbulbs do get hot when lit - even cfl bulbs get a bit hot.
Which gas does not react at all it is use in light bulbs so that the metal in the light bulb can get very hot without burning?
Modern light bulbs contain no gases whatsoever; a vacuum.
