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.
Yes, the wattage is just the power consumption. A 30 watt Fluorescent will give more or less the same light as a incandescent bulb or 60 watts, which is the limit for your fixture for incandescent bulbs.
Fluorescents are always 3-4 times more efficient than halogens which are a version of incandescent bulb.
The light spectrum from an incandescent (a bulb) is closer to the spectrum of the sun than what comes from a fluorescent.
Lumens measures how bright it is, watts measures how much electric power it uses up. An old-type incandescent bulb produces about 10 lumens per watt. A halogen produce about 13 lumens per watt. A fluorescent (energy saving) bulb produces about 50 lumens per watt. LEDs produce somewhere around the same as a fluorescent.
You would need a 12 Watt flourescent bulb

Very little, but it is noticeable, with a bright light in a small room. A light bulb puts out between 9 watts (energy-saving fluorescent light bulb) to approximately 100 watts (bright incandescent light bulb). Your average bar-heater, for comparison, puts out about between 1200-2400 watts.
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.
220 lumens is equal to a tungsten incandescent light bulb of 15 watts. Halogen lamp 20 watts. Fluorescent lamp 60 watts. LED lamp 60 watts. high pressure sodium vapour lamp 117 watts. Mercury vapour lamp 50 watts or 17.32 candle power
Halogens are about 30% more efficient so 300 watts incandescent is equivalent to about 210 watts halogen. It's also equivalent in brightness to about 60 watts CFL.
