If you're talking about the spectra of the two light sources, the sun's spectrum is fairly even from the red end through to the violet end. An incandescent light bulb's spectrum is much weaker at the violet end, which is why it seems to give off a "warm" light. Fluorescent lamps are stronger at the violet end in most versions, but they can be "made to order" to seem warm or cool in their spectrum. Also, sunlight is dangerous because of its brightness and the presence of ultraviolet radiation.

There is a difference which the present day science
does not know.
Who were the first to calculate the velocity of light? The
Rig Veda Bhashyam by Sayana Madhava gives the following
Sloka praising the Sun:
Yojanam sahasre dve, satadve, dvecha yojane
Ekena nimeshardhena kramamaana namosthuthe
One Yojana equals 15788.8 meters, and half of Nimesha
equals 8/75 fraction of a second. This gives the velocity
of light as 325940 km/s. We have to remember here that the
above value is an approximate one intended for easy
remembrance, like remembering the value of pi as 22/7. It
is better than the value 215000 km/s given by Danish
astronomer Ole Roemer in 1676. Having discovered so many
things, it is only logical to expect that our ancestors
must have used light as the standard for length
measurements; after all, modern science considers velocity
of light to be a Universal Constant! The word "kramamaana"
of the above Sloka has the hidden meaning of gradual
minute change which occurs over thousands of years.
Our ancient seers did not use light as a standard for
length measurement. How can that "which bends" be
called unchangeable? Every created thing is subject to
change by time; there is nothing like an universal
constant. And the velocity of light is no exception to
this law. The velocity of light of our Sun was greater
in Krita Yuga than what it is now, even if it is by a
small fraction. The velocity of light is proportional
to the stored energy in the Sun or any other star.
Modern science also accepts that the Sun has lost a lot
of energy over billions of years. Then, there must be
some other stars in the universe which have greater
stored energies than the Sun, and are emitting light
which is faster than that of the Sun? Yes. Modern
science will confirm this after it develops more
sophisticated equipment than what they have at present.

Very simple concept....sun light is natural and light from an electric bulb is artificial...Sun light has the power to provide life on earth ie for plants to prepare food by process called photosysthesis.Its not so with the light from electric bulb.
One very big difference...sun light is free and available in abundance...electric light is not free.
There are many other differences....but these importance points could provide the ans.

There is a great difference. sunlight gives energy and life to all the creatures i.e. human beings, animals and plants on the earth, while electric light gives clear visions in the dark.

the two forms of light are basicaly the same. both are electromagnetic waves. however they differ only in the energy content. rays from sun have high frequency, low wave length, and high amplitude. wave from bulb have relatively low frequency, high wavelength and low amplitude. this difference is due to the difference in temperature of the tw sources mentioned. larger the temperature more will be the energy content of the waves prodused

the light from sun are non monochromatic radiation but light from bulb is monochromatic. sunlight wavelength varriesfrom 4000-7000 anstrom but ligt of bulb is of the constant wavelength.

The sun was not produced chemically, has more energy, more light, never burns up. It is a gas ball too.

sun light is naturally occurring light from bulb is man made

1) brightnesss
2) sun has loads of harmful wavelenths in it wheres bulb has only visible light
3)UV rays is THE distinguisher

they both produce light and heat, however as one already said the wavelength is different, and sunlight also has ultra violet rays.
