thanks , current spot lights are cheapy nasty ones no covers but found some new ones which have built in shields so no fussing about wih extra covers. So will be ordering those.
The room is not too wide about 2.5 meters so with both sides up about 50cm either side its only 1.5 meters ro so covered easiyly enoght to get my arm down it.
Looked into sound proof rock wool and it would come to about £200 instead about £20 for normal one so will go with that most likely.
