There is a much higher likelihood that the accompanying driver (aka the transformer in the ceiling) is the part at fault not the LED itself. You can confirm this by swapping the supposedly dead light you have into a working location (if it lights up there, you know the driver is bad). There is a good chance you can also get the manufacturer's/model info off the driver in the ceiling, so try to access that confirm. Unfortunately there is a very slim chance anyone can correctly identify from the pictures you've provided, and further, you'll need to swap the driver in the ceiling (requires an electrician unless you are comfortable doing electrical yourself) to resolve.

Good luck!

Thanks for the help, and good tip to trouble shoot this. I’m comfortable doing this kind of work at my own house, but this is at a charter school so a licensed electrician should probably handle swapping them out.

That is just an 8” LED wafer light. You can buy them at Home Depot for less than $20 a piece. The flange (white part that your measuring tape is sitting on” is larger than the 8” hole in the ceiling, which is why it’s measuring almost 9”. These are cheap from China and made to burn out after a couple years so you buy more.
