Incandescent bulbs work by heating a filament (usually made of a tungsten compound) until it glows white. Up to 90% of the energy needed goes to waste in the process, since humans can't see into the infrared.
Fluorescent bulbs work by exciting the molecules of Mercury vapor into emitting ultraviolet light, which is then absorbed by the white phosphor coating and re-emitted as visible light. It's much more energy efficient -- and more importantly, nowhere near as hot.

What happens when a light bulb get more than 120 volts?
The filament will melt AND MAYBE THE LAMP WILL EXPLODE
What star is hotter a star giving off red light or blue light?
That question is a little tricky. What is certain is that if the light is coming from a hot object like a glowing heater element, yellow light indicates that the element is hotter. It is also true that a single photon of yellow light carries more energy than a single photon of red light and is "hotter" in that sense. So in general, yellow light is hotter, but if you are simply talking about narrowband filtered light from a single source, a human will not ordinarily be able to sense the difference, and which color is more intense will depend on the spectrum of the light source.
Which is hotter an electric fire or a light bulb?
An electric fire has a wattage of between 1 and 3 kw depending on the model - a light bulb can be anywhere between 40 and 120w.So an electric fire is a lot hotter.Another AnswerIf, by 'hotter', are referring to temperature, then lamps operate at a far higher temperature than an electric fire (white hot vs red hot!). If, by hotter, you are referring to the amount of energy consumed, then electric fires win!
Which of the areas of technology best classifies the light bulb?
The incandescant light is more of a heat bulb than a light bulb, being 200% less efficient (on average) in producing the same amount of light (measured in lumens) than a fluorescent bulb. That being said, the light bulb would be considered part of a luminaire.
Does a 25 watt light bulb draw more current than a 60 watt light bulb?
No, a higher wattage INCANDESCENT light bulb uses more current than a lower wattage INCANDESCENT light bulb. Some CF and LED bulbs are rated by the amount of light that an incandescent bulb would produce, but they are also rated by the wattage that they use.
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.

Do 54 watt light bulbs burn hotter than 40 watt bulbs?
Yes because the more watts a light bulb means it lets out stronger light, but with more light it creates more heat, so the more watts in a light bulb = more heat and stronger light

Is incandescent light cooler than fluorescent light?
No, much hotter.
Are blue stars hotter or cooler than red stars?
According to Wien's law, red stars are cooler than blue stars. This concept can be easier to understand using a light bulb. For example, when you turn off a light, the temperature of the bulb will decrease and you will notice the bulb turning red. The cooler light becomes, you will notice the obvious change in brightness and the color shifts towards red and the intensity is lowered.

What is a word that means a light bulb that uses more energy than a fluorescent light bulb?
incandescent
What forms of energy does the electric light bulb made?
First let us understand the different parts that go to make up the light bulb shall we? The key component in a light bulb is the filament, this filament, ususually a thin piece of wire, is connected to two contact points. These points are then connected to the metal base of the bulb. When the bulb is attached to the light socket a circuit is then made. As the thin wire is part of the circuit it will have electicity passing through it when the power is switched on. The bulb glows because of the filament is thinner than that of the rest of the circuit. The filament gives off heat energy and begins to glow, this glowing we call light energy. You now have two forms of energy.
Does a larger battery contain more energy than a smaller light bulb?
A light bulb contains no energy so, Yes, a battery of any size contains more energy than any light bulb.
Why is the light bulb more important than the Internet?
the light bulb is just important yeah you dumb computer
