Light and Darkness are both aspects and elements simultaneously. The way I like to describe them is by comparing them to adverbs. They are modifiers, but can act as what is being modified as well.

Also, it should be noted that Light is naturally Umbral aspected, and Darkness naturally Astral aspected. A good example of the reverse, Astral Light and Umbral Darkness can be found on the First and the Thirteenth, as it was those aspects that caused their respective floods.
