An incandescent light uses electric current passing through a wire with a high resistance to current flow. That makes the wire very hot and it glows, producing the light. A fluorescent light uses electricity to charge a gas in a tube. The charged gas glows, producing the light. For the same amount of light, more electricity is needed in an incandescent light than in a fluorescent light, but developing and building fluorescent lights required more advanced technology than did incandescent lights.

Fluorescent light bulbs are extremely long-lasting. Most are designed to last over 10,000 hours. This comes out to approximately 416 days of continuous 24 hour usage. Even if used only 8 hours/day, the average fluorescent bulb should last over 3 years.
The weight of one 8 foot fluorescent light bulb is 1.2 pounds. Fluorescent light bulbs are available in many colors and color temperatures.
Yes. They're cool compared to incandescent bulbs of the same light output, but they do produce some heat.
A CFL light is a Compact Fluorescent Light.

The basic fluorescent light fixture is AC, although there are fluorescent lights powered by DC.

Depending on the size of the light and how it is used, a fluorescent light can have a lifespan of anywhere from 8,000 to 30,000 hours. Fluorescent lights tend to lose their brightness over time, so it is recommended to change the light bulb before it burns out completely.

No, the ballast's output is not matched to operate a fluorescent bulb.
