That type of bulb makes its light by making a small piece of tungsten wire glow at around 3000 degrees Celsius. Obviously that process also produces a lot of heat so incandescent bulbs are inefficient, i.e. they produce not much light for a lot of electric power used.
Tungsten is used because it has the highest melting-point of all metals.
In an incandescent light bulb this is the filament. It is usually made of tungsten.

An incandescent light bulb, incandescent lamp or incandescent light globe is an electric light which produces light with a wire filament heated to a high temperature by an electric current passing through it, until it glows.
Incandescent light bulbs produce light when a filament made of tungsten wire is heated by an electric current flowing through it. The filament glows and emits light as it reaches high temperatures.
An incandescent light bulb uses a filament that produces light by heating it until it glows. This type of light bulb emits a warm and yellowish light.

He named his invention the Incandescent Lamp, But it's commonly referred to today as the Incandescent Light Bulb.
The incandescent electric light bulb was invented by Thomas A. Edison.
The resistance of a light bulb varies, depending on the type of bulb, the power rating, and the temperature. A typical incandescent 60 watt bulb, for instance has a cold resistance of about 30 ohms, and a hot resistance of about 240 ohms.
The filament of an incandescent light bulb is actually significantly hotter than lava. Temperatures may exceed 4,000 degrees in some bulbs.

No, a higher wattage INCANDESCENT light bulb uses more current than a lower wattage INCANDESCENT light bulb. Some CF and LED bulbs are rated by the amount of light that an incandescent bulb would produce, but they are also rated by the wattage that they use.
