No, an incandescent bulb i.e. a bulb that emits light by the generation of heat, emits white light and is therefore not monochromatic. For a source to be monochromatic, the light emitted must be of a single wavelength.
Since an incandescent light bulb is an appliance that has a fixed electrical resistance, operating it at less than its rated voltage means that it will draw less than its rated current and will produce less light.

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.
It is the filament.

The output of bulbs varies. A typical output of a 60W incandescent bulb is 680 lumens.
Both bulbs output the same amount of energy. The difference is in how much of that energy is output as heat vs the energy output as light. In a standard incandescent light bulb about 10% of the energy is output as light while the other 90% is output as heat. This makes the bulb only 10% efficient. For a florescent bulb the output of light is about 50% and the other 50% is output in heat. This means that a fluorescent bulb outputs five times as much light for the same wattage as a standard incandescent bulb, hence you can get the equivalent of 100 watts of light output for only 20 watts of electricity.
Incandescent: 10-12 lumens per watt CFL: 50 lumens per watt.
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.
Since an incandescent light bulb is an appliance that has a fixed electrical resistance, operating it at less than its rated voltage means that it will draw less than its rated current and will produce less light.
Incandescent
He named his invention the Incandescent Lamp, But it's commonly referred to today as the Incandescent Light Bulb.
Input to light bulb is Electricity and output is light.
The incandescent electric light bulb was invented by Thomas A. Edison.

A light bulb that uses a filament is also known as an incandescent light bulb.
