Seeking a translation of the phrase "Let there be more light" into Latin

Hello,

I need a translation of the phrase "Let there be more light" from English into Latin. The phrase is to be used as a personal "motto" in a fraternal organization. The context... well... it's basically the same as with the phrase "Let there be light", as it is used in the Book of Genesis in the Torah or in the Holy Bible, but in greater quantity. Hope that was specific enough.

Thanks,

Jacob
