The four inch air space you have is plenty. But is 3 1/2" insulation enough where you live? Use gasketed electrical boxes on the ceiling to prevent air leakage. The insulation can go tight against & over the box. Make the ceiling as air tight as you can by using a 6ml. polyethelene vapour barrier under the insul., caulked at all joints. Moist air contacting the cold tin will condense & soak your insulation.
