Lux Runes?! Please Help

I just recently got into level 20 and now I can actually get ruins for my champions. it's really confusing because I know some peoples strategy is based off of meta and others base it off of own personal needs and preference. I however would like to mainly focus around meta-so that I know that it works and will fit together. First champion that I ever clicked with was Lux. I play her support because I find myself playing her stronger as a support then as a mid laner. My question is whats a good sturdy ruin set playing Lux as a support build? even though I do not play a lot of other supports aside from Sona I would like this build to also fit multiple supports and not just the Lux on her own. thanks!
