joker97: the reason I am after LED light is some come with an insulating shell so I don't need to have a gap cut out of my pink batts ... does yours do that or have a way of doing that?
sorry if my explanation is poor perhaps someone else can help me explain
I think what you are talking about is the actual light fittings. These LEDs may not require any clearence, due to no creating much heat. However if someone happens to put a conventional bulb into the fitting, and you have put insulation over the fitting, then this could be a fire risk.
What I would like to see is LED bulbs and decent downlighting fittings for them, that can also be insulated over. I am noit sure that Edison screen, bayonet cap ones that are retrofitted into existing fittings could be used in such fittings, as you can also install conventional bulbs in those same fittings, which need a large insulation gap to prevent a fire risk.
The main ones I have seen so far are all in one fittings/light bulbs, where if the light bulb blows you have to replace the fitting. I wouldn't buy these due to the high risk of a business disappearing or the design changing, and you then can't get replacements, meaning your room will have odd light fittings.
