I am concerned about the heat CFDL's generate and the inability of placing insulation nearby the fitting. I have been reading by not insulating due to downlights heating/cooling efficiency of the home will decrease, which is something I do not want! This sole factor is swaying me to standard lights. In addition downlights are not airtight (correct me on this). Having 10 in a large room could be as bad as having the window slightly open (draft)?
I really want downlights, but only if the above factors can be address. Any advice?
