just a quick one...a job we are downing includes installing downlighters along a corridor of a house. The void is only 90mm. I want to use fire rated 240V downlights, but before buying (from the internet) a lot of the shallower ones i'm looking at doesn't specify a clearance dimension around the fitting. Most do, ie/ 100mm, 50mm, 60mm etc etc. Is this distance determined by the manufacturer? or is there a set standard for this?
