well they are needed because without them we wouldn't be able to see!
We need it for light.
Not necessarily. They can be brighter, or less bright. Both the energy saving light bulbs and the old-fasioned incandescent light bulbs come in different powers.
Fluorescent bulbs generate light by using an ionized gas and electrical discharge, whereas regular light bulbs generate light by using heat within the filament contained in the bulb.

A light snack!
The heat and light we receive from the sun is radiant energy, as is the light we obtain from light bulbs.
Headlight bulbs, high and low beam, parking light bulbs, signal light bulbs, brake light bulbs, dash light bulbs, interior light bulbs, plate light bulbs, etc.
A light bulb emits light energy, which is useful for illuminating a space and providing visibility. Some light bulbs also produce heat energy, although this is often considered a byproduct rather than a primary source of useful energy.
Usually the light bulbs used are resistive components, but the energy savers used now a days are inductive components and they are used because they consume reactive(inductive) less useful power and save useful or real (resistive) power.
Incandescent light bulbs and halogen light bulbs are examples of light bulbs that produce heat.

Domestic light bulbs are simply the light bulbs (usually of the filament type) used in the home.
No, not all light bulbs produce polarized light. The polarization of light depends on the source of light and its characteristics. LED and fluorescent light bulbs can produce polarized light, while incandescent bulbs generally do not produce polarized light.
Industrial light bulbs typically have larger wattage than commercial light bulbs. This is because commercial light bulbs are more commonly used in public as opposed to private homes.
