An incandescent bulb differs from a fluorescent based on how it produces light. "Incandescent" means producing light through heat, this is essentially how an incandescent bulb lights. As current travels to the tungsten filament, the filament heats and lights up as the tungsten filament begins to deteriorate and eventually fail. Fluorescent bulbs produce light when current excites gasses inside the glass envelope. As the gasses get excited they emit photons. Interestingly, the light produced by a fluorescent bulb does not fall along the visible spectrum until it passes through the white, phosphor coating on the inside of the bulb. And there you have it.
In an incasescent light the light is emitted directly from the element.
In a fluorescent light the element excites a gas which in turn excites a secondary emission surface this then emits the light.
Less power is needed per candella of light emitted from a fluorescent light but it is more expensive to make in the first place.
This is correct, as mentioned above, I found this article written by Specialist Paints Online with gives a comparison

The reason fluorescent bulbs provide more light with less electricity is the efficiency of exciting the fluorescent gases versus the controlled burn of a filament. The filament burns which wastes a lot of the 60W bulb's energy as heat. The dandy little 13W fluorescent makes as much light, but isn't burning anything.
The draw-back of fluorescents is the quality of light, and the inability to control the intensity -- the fluorescent is either full-on or full-off, whereas the incandescent bulb can be dimmed with a rheostat.
the incandescent light bulb is powered by energy through waves that generally relate to the fuse and the compact fluorescent light bulb uses electricity to power the bulb
An incandescent has a filament which heats and throws off light when electricity flows thru it and a fluorescent has gas in it that glows when electricity passes through it.

Incandescent lamp are: 1-low energy efficiency. 2-low initial costs. 3-produces warm color light. 4-reflector can be integerated within the bulb. 5- short bulb life.
on the other hand:
Fluorescent lamps: 1- high energy efficiency. 2-high initial costs due to extra components. 3- produces cool color light. 4- long bulb life.
In terms of energy efficiency, a fluorescent lamp has a greater efficacy than an incandescent lamp -in other words, it will require a smaller input power to produce the same number of lumens.
In terms of the environment, a fluorescent lamp contains Mercury, has far more components, and requires more energy to manufacture than an incandescent lamp, so is more hazardous to the environment.
Incandescent sources give a continuous spectrum of light, as does sunlight.
Florescent sources give separated lines of colors.

No, compact fluorescent bulbs run much cooler that an incandescent bulb. A CF bulb can be unscrewed when the lamp is on whereas an incandescent will give you a bad burn if this is tried.
Relatively cool, yes, especially if you compare them with incandescent lightbulbs.
If the question is what wattage compact fluorescent (CFL) lamp has a similar light output to an incandescent lamp of a given wattage, the ratio is usually about 4. A 60W incandescent can be replaced by an 13-15 W CFL lamp. A 60W CFL lamp can replace a 300W incandescent lamp.
A regular incandescent bulb uses a lot more energy than a compact fluorescent to produce the same amount of light. Most energy used by an incandescent bulb is wasted as heat which does not give off visible light. Incandescent bulbs are cheaper to buy, but they have shorter lifetimes than other alternatives.
Yes, if it fits the socket and the light fitting, or lamp fixture, with its cover or shade. You will not be able to dim the compact fluorescent as you did the incandescent (unless you have a really fancy dimmer).

CFL ARE GENERALLY CONSUME LESS THAN 50% VERSUS THE INCANDESCENT LAMP LUX COUNTERPART. YOU CAN USE WITHOUT WORRIES FOR IT WILL NOT CAUSE OVERHEATING DUE TO OVERLOAD AND INTERFERENCE PROVIDED SAME VOLTAGE RATING AND YOU CAN FIND WIDE VOLTAGE RANGE MODEL TO BEAT VOLTAGE FLUCTUATIONS. SOME MANUFACTURERS DESCRIBE CFL AS ENERGY EFFICIENT LAMPS.
There are quite a few differences between a compact computer and other computers. Compact computers are easier to take with you.

A compact fluorescent lamp (CFL), also called compact fluorescent light, energy-saving light, and compact fluorescent tube, is a fluorescent lamp designed to replace an incandescent lamp; some types fit into light fixtures formerly used for incandescent lamps. The lamps use a tube which is curved or folded to fit into the space of an incandescent bulb, and a compact electronic ballast in the base of the lamp.
There are many differences between a compact SUV and a regular SUV. The main difference that is most apparent to consumers is the difference in size and storage capabilities.
Yes, the compact fluorescent light produce more light as compared to the same wattage of incandescent light, it is scientifically proved.
The main difference between the Canon Selphy CP900 and the Canon Selphy CP810 compact printers is that the CP900 has built-in wireless and the CP810 does not.
