Yes.
Light bulbs in order of the least to most energy efficient : incandescent, halogen, fluorescent, LED. For home owners, most reasonable is the CFL lightbulb, which is cheaper and longer lasting than the LED.
Incandescent lights are expensive to run (they give off a lot of heat was well as light), incandescent lights are much more efficient. However modern LED light bulbs are better (more efficient) than both incandescent and fluorescent lights so in the future you will see a change to the use of these.
Yes. Part of the energy is converted to light, part to heat. The percentage depends on the type of light bulb. Fluorescent and LED light bulbs are more efficient than incandescent light bulbs. A 60-watt incandescent bulb will be uncomfortable to remove from the socket with your bare hands after turning it off. However, a 100-watt bulb will burn you if you remove it with your bare hands after turning it off.
Incandescent and halogen light bulbs use more energy than compact fluorescent lights and LED lights. Fluorescent lamps with magnetic ballasts use more energy than fluorescent lamps with electronic ballasts.
Well, you would basically have to have a thorough understanding of how each one works. But basically, the incandescent lightbulb converts electricity to heat first, and a lot of energy is radiated away in the form of invisible infrared light; this is the reason it is very inefficient.
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.
It is about 5 times more efficient than the incandescent bulb, in other words for the same light a fluorescent uses one fifth the electric power.
Definitely fluorescent. Incandescent lights are extremely inefficient and spend most of their energy producing heat rather than light. This is why an incandescent lightbulb gets so much hotter than a fluorescent one.

Fluorescent lighting is much more energy efficient than incandescent lamps, usually by as much as 60 to 80%. That also translates into a corresponding energy savings. I don't recall the exact figure off hand, but the light output from a fluorescent lamp is about three times it's rating. For instance, a 40 watt fluorescent puts out the equivalent light of a 120 watt incandescent bulb.
Although incandescent light bulbs remain a convenient source of light, as they have been for a long time, they are now an obsolete technology, because there are other sources of artificial light which are much more energy efficient. Fluorescent lighting is more energy efficient, and LEDs are even more energy efficient that fluorescent lighting.
Fluorescent light bulbs use less electricity for the amount of light produced.

comparing to the traditional light bulbs energy efficient fluorescent light bulbs uses 25% to 75% energy and saves money also and it lasts up to 3 to 25 times long so there is no need to replace energy efficient fluorescent light bulbs often.
incandescent
Fluorescent tubes last longer and supply more light per watt of energy consumed than an incandescent bulb.
Fluorescent is more efficient. Incandescent bulbs should not be used any more, except for some special purposes (mainly where they keep something warm).
