downlights in false ceiling tiles?

[decdastardly]

Thanks for all the replies I'm still waiting to get get into the job and those ply boards are still kicking around in the back of the van. There's no spare tiles on the site and I know I've snapped a few before just during some clumsy poking around so I'm careful now! Plus I know those springs are like mousetraps on some of them!

You can always use 6mm MDF which is non-flammable
