Um... you don't actually have a theme because Luke does not mean light. I'm sure a million websites have told you that it does, but, as someone who actually does ancient history and languages, I promise you that it doesn't. At all. Likewise Nora. No light-related meaning whatsoever. That said, there are lots of beautiful names that have light-related meanings (I'm going to count moon/sun/star meanings for the sake of variety), for instance:
Clare (my name) means light! It has also gained popularity recently. Growing up, I was the only Clare in my circle besides my aunt. Oddly enough, "light" was apparently my first word.

Yep, I have a Claire. Light, bright, clear.
Hugo / Hugh means Bright, but more in the way of intelligence.
Re: Names that mean 'light'
*eta checked it out. Ellen does mean "bright, shining light" as does Elena. My guess is that Any variation of Helen/Helena will have that meaning.
