Downlight with Vapour Barrier

I'm keen on having downlights in the bathrooms like the JCC V50 shown below. I am installing a polythene vapour barrier in the ceiling as there is insulation and loft above and a bathroom is obviously one of the most humid spaces. How to I deal with the downlight as that will make a pretty big hole in my vapour barrier?

You get down-lights that are about 15mm tall. A service batten 50mm tall will be enough space for the little control box.

 

Is that creating a 50mm void under the vapour barrier and above the plasterboard then?

 

I'm using Resilient Bars. So I have stuck the polythene to the underside of the truss bottom chord and then screwed the Resilient bar underneath. The resilient bar is 16mm high so there is a 16mm void.

So you could use something like. These are 25mm deep.  16+12.5, gives 27.7 height, if you are using 15mm plasterboard then 31mm height.

 

Thanks, that looks like an option. It has a driver too, but I can probably bulge the vapour barrier slightly where that goes.
