Incandescent produces about 10 lumens of light per watt of electricity
Halogen produces about 13 lumens per watt
Fluorescent and CFL produce about 50 lumens per watt
So Fluorescent is the most efficient.
CFL stands for Compact Fluorescent Lamp, and they are an energy-efficient alternative to incandescent bulbs. CFL lamps can be used to replace these bulbs, and they can be placed both indoors and outdoors.
Relatively cool, yes, especially if you compare them with incandescent lightbulbs.
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).
None or a negligible effect. Similarly to incandescent or fluorescent tubes, they light up your work area so you can see what you're doing at the computer.
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.

Compact fluorescent lights are used in place of incandescent lights, but use one-fifth or one-third of the electrical power. They also last about ten times longer, making them very efficient for lighting rooms.

about 5 times as efficient.
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.

Yes, the compact fluorescent light produce more light as compared to the same wattage of incandescent light, it is scientifically proved.
Relatively cool, yes, especially if you compare them with incandescent lightbulbs.

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).
An incandescent bulb gives off more heat than a fluorescent bulb.
Compact fluorescent light bulbs are pretty energy efficient and are energy star rated.
