Extremely low suspended ceilings?

[Kantan]

I've been scouring the web for some details on this, unfortunately I can't find anything.

1. I have a client who lives in a condo in NYC with concrete ceilings
2. They want recessed lighting
3. "Exactly"
4. The ceiling is to be dropped by only 2-1/2"
5. The light in mind is a 1-1/4 LED light (Extremely low profile)
Ex:

... my question is, what is the NEC code on drop/suspended ceilings like the one explained here? (if they exist at all) The low profile LED lights are a fairly modern invention so I'm not even sure if there's any word on if this meets code.

I'm also curious on NYC or NEC code for the suspended ceiling structure, steel or wood under ultra light 1/2 gypsum board for ceilings with wiring and maybe a "mini" junction box (that might be a stretch). I know 5/8 FR board is the norm and certain for meeting code, but would anything change for this application?

*I beg, if you can, please reply only on NEC and NYC code. I really want to keep this thread free from alternative lighting suggestions, they've all been considered (yes, all including fabric ceiling options), but I would like to explore this option. It's new and intriguing.

I suggest you get an electrician involved with this. With that said.......
