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 about 5x as efficientso a 12W will give about as much light
Fluorescents are always 3-4 times more efficient than halogens which are a version of incandescent bulb.
A 20 watt incandesent bulb is dim. For a medium sized room you need 100 watts. A 20 watt halogen bulb is brighter but still quite dim. These are marketed as low-energy but they are not. For a medium sized room you need 80 watts. A 20 watt fluorescent bulb can light a medium sized room quite brightly. This is a genuine low energy bulb.
F17 on a fluorescent bulb packaging typically indicates the type of bulb and its wattage. In this case, "F17" refers to a T8 fluorescent bulb that operates at 17 watts.
An incandescent bulb gives off more heat than a fluorescent bulb.

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.

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
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 bulbs are generally better than incandescent bulbs in terms of energy efficiency and lifespan. Fluorescent bulbs use about 75% less energy and last up to ten times longer than incandescent bulbs. Although incandescent bulbs offer warm light and are less expensive upfront, their higher energy consumption and shorter lifespan make them less economical over time. Therefore, for cost-effectiveness and energy savings, fluorescent bulbs are the superior choice.
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.
