Insulation and clearance recessed lights

[TheLeester]

Hi, my 1930s house has next to no insulation in the loft. I did board with 22mm T&G and I thought with the amount of junk that is on top of it would be plenty of insulation. The insulating properties of childrens toys dont seem to be as good as I thought so I plan to put down some proper insulation, probably 100mm of rockwall.

We have halogen recessed spotlighting throughout the house and so this is obviously intruding into the loft space between the joists. A fair amount of heat is given off by them. Should I leave a clearance around them or is the heat resistance of the insulation material such that it can safely been overlaid on the lights ?

Re-post this in the "Electric Section" as this is more for the electrician to answer. I believe you can buy a heat shield like a updown flower pot which is fireproof but I don't know much about them.
