In addition to books4languages.com's reference to the humorous aspect of the phrase I find it appropriate to mention the AC/DC's song "Let There Be Rock" where this phrase is used in a similar humorous way

"let there be light" This phrase is spoken by God in the Bible during the creation story:
1In the beginning God created the heaven and the earth. And the earth was without form, and void; and darkness was upon the face of the deep. And the Spirit of God moved upon the face of the waters. And God said, Let there be light: and there was light. And God saw the light, and it was good; and God divided the light from the darkness.
If you have heard this in a religious sense then the speaker is referring to the Bible.
However, "Let there be light" (shortened) is sometimes said humorously when one switches on a light.
