stupidness and whatever
A light source made from nature could be sunlight streaming through a window or firelight from a campfire. Alternatively, bioluminescent organisms like fireflies or certain types of algae can also serve as natural light sources.
You do not found C.F.L. bulb in nature as such. So it is an artificial or man made source of light. It consumes very less energy. As it does not gives out heat.
jelly fish nature sources of light.
what is man-made light
That is any source of artificial light (not a naturally occurring light)oil lampsgas lampscampfireselectric lampscandlesetc.
The sun is an example of a natural light source. A source which gives of light that is natural (not made by electricity) is a natural light source.

because of the nature of source producing it...
The source of light used in a diffraction grating is typically a monochromatic and collimated light source, such as a laser. This type of light source emits a single wavelength of light in a narrow, parallel beam which is important for producing sharp and distinct diffraction patterns.
Aluminium is not normally a source of light. I suppose if you made a large mirror out of it you could turn that into a secondary source.
The speed of light in a vacuum is constant at about 3 x 10^8 meters per second. The nature of the source of the light wave does not directly influence the speed of light in a vacuum. The speed of light is determined by physical constants in the vacuum, such as the permeability and permittivity of free space.
A candle is a natural light source because it is derived from natural materials such as wax and a wick.
