Earlier I asked about downlighters and several replies suggested LED
panels, having experimented with a few types of downlighters I'm
unimpressed so want to explore the options with LED panels. The
problem is that it's not possible to look at them in shops, or to
pick one up (cheaply) to experiment with, so I hope there's a bit
more experience with them out there in uk.d-i-y.

The circular panels penetrate the ceiling but I can't find any
mention of them being "fire rated", are there any that are? If not,
what do people do?
It seems that some (most?) of the rectangular and square panels can
sit under an unbroken ceiling, which would be wise because when one
fails it probably won't be easy to find a replacement to fit into a
girt big hole.

It probably won't be a problem with square or rectangular ones. Many
panels are likely to be standard sizes, to directly fit in place of
the tiles in office suspended ceilings.

you can get ceiling tile up to size 4 by 8 ,
you can cut them easily into any shape

Yes, but most office lighting comes in standard sizes that match the
sizes of lift-out tiles that are commonly used. It doesn't matter that
you can get much larger tiles, the common tile sizes and the matching
lights don't change.

they're easy to cut i'm looking up at my ceiling right now it's tiles
