Hi
We have installed LED downlights throughout our house. I understand these don't get as hot as halogens. Should they still have downlight covers? I have read conflicting advice about this in my googling. My builder says they aren't needed and he will make sure they are clear of any insulation. If he is cutting holes in the insulation so it isn't in contact isn't it reducing it's efficiency? If we have the covers can you just lay it over the covers-is this how it works?
Thanks
Donna
