Ok, it's obvious I know what light is, but I want to give 'the best vote' to the person who gives what I think is the best explanation!

It is an interesting question.
Light is what produces the sense of vision,it consists of photons which are defined as packets of energy!
Light possesses dual character i.e. Wave and particle nature!
It depends on what condition you take for testing the behavior of light!
Foe example,Light shows diffraction which means it is a wave but it also shows PE effect which shows it behaves as a stream of particles!
Hope this will help you!

A copy and paste from Wiki is probably going to be the best answer. lol
In my words (not a scientist), Light is composed of photons, particles of light that act and travel as waves. The wave pattern they travel in is determined by the source of their emission (eg. Neon is red, Xenon is white/bluish, a cool carbon fire is orange, natural gas is blue, etc) or the object they reflect from. This makes things look shiny or dull, blue or red, etc.
The End :)
