Ambient Ceiling Lights

I'm trying to make a starter home for my sims and to share in the gallery, so I want content that's not hidden to someone who downloads (no secret stuff). I'm not opposed to using things pack or expansion specific, I just don't want mods or CC, etc. Anyway, in the penthouse in city living there's an ambient ceiling light. I also noticed it in a lot I downloaded. Where and how do you get these? it shows as a $0 cost, so it would be very helpful in a starter home!

This thread says you can find them in the gallery, but I'm not seeing them. carls-sims-4-guide.com/forum/index.php?topic=22096.msg392692#msg392692
