fluorescents are about 5x as efficient
so a 12W will give about as much light
the most economical is the incandescent bulb because the power of bulb is low only while the fluorescent lamp is low and additional the power of ballast from 10%-20% power consumed.but the fluorescent lamp is 5 times brightly the incandescent bulb.
A 13-15 watt compact fluorescent bulb (CFL) or a 9-11 watt LED bulb is roughly equivalent to a 60 watt incandescent bulb in terms of light output.
not all incandescent lamps (bulbs) can be replaced by fluorescent lamps because there are some applications where there is no acceptable or equivalent fluorescent lamp. In some cases, other technologies may be useful--HID or LED lamps. There are some applications where the incandescent source, especially the tungsten-halogen type, still rules.
no because it would blow up because the socket would draw 13 watt not 9 watt
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).
Fluorescent light bulbs are typically more energy-efficient and produce more light for the same amount of power compared to incandescent bulbs. So, a fluorescent light bulb may appear brighter than an incandescent bulb with the same power rating.

So to replace a traditional 60-watt bulb, buy a 15-watt CFL: 60-watt incandescent / 4 = 15 watts. Note: Some brands of 60-watt equivalent CFLs still do not seem to give off as much light as a 60watt incandescent bulb.
An incandescent bulb gives off more heat than a fluorescent bulb.
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.
An incandescent bulb is less energy efficient than a fluorescent bulb because it produces more heat than light, wasting energy. Fluorescent bulbs are more energy efficient as they produce less heat and more light. Additionally, fluorescent bulbs have a longer lifespan than incandescent bulbs, lasting up to 10 times longer.

Fluorescent tubes last longer and supply more light per watt of energy consumed than an incandescent bulb.
Fluorescent bulb is the more efficient one as compared to incandescent bulbs.
