What type of basement ceiling is this?

Hi folks,

On the finished side of my basement (half finished and half not) we have old-school fluorescent lights. There are 4 bays that each have 4 long fluorescent lights. We hate them and theyre awful 😊. Id like to replace them with recessed LED lights (either the normal kind or the super-thin ones that Ive seen).

My question is what type of basement ceiling is this? Im used to either no ceiling or a drop ceiling, but Ive never seen this type before. Below is a picture of the ceiling, along with a picture from the unfinished side looking above the ceiling. It almost looks like there are 2x4s going across the joists that the ceiling is attached to. I just cant figure out how theyre attached without taking some down. Are they nailed in? Glue? Wasnt sure if I could put the lights right into these ceiling tiles. And somehow would like to close up the existing fluorescent bays.

Acoustic tiles with tongue and groove edges mounted on furring strips. Long edges along two sides are stapled to the furring strips and then covered by the mating tongue on adjacent tiles. Installed continuously from one side of the room to the other. Not easy to remove or replace internal tiles without looking like a patched area. Easy enough to cut openings for lights or electrical boxes HOWEVER they may contain asbestos if installed before the 1970s.

Those are 12x12 Armstrong tiles. They are beveled tongue and groove on two sides, they are typically stapled and the next piece covers up the flange on the previous piece, so all the staples are hidden. And they are pretty impossible to work on, if you need to rework anything you about need to start over.

The ceiling will usually be strapped 12" on center with 1x4 strapping that is perpendicular to the joists.
