Green Building Q&A: Insulating recessed lights where there is no attic

I have an interesting problem. We have seventeen, 6" recessed lights in a ceiling that has no attic above it. We conducted an energy audit (we're putting in a 9 kw solar system and a host of other related changes) and found these to be a serious source of energy loss. The area where these are located is a single story, family room that just has the heat sucked out of it in the winter. These recessed lights are like chimneys. While I am replacing most of our recessed lights with LED's, this one area I haven't touched as I need to insulate first I don't know if these cans are IC, but even so, those make me a little nervous, but I also have ZERO access from above. Everything will have to be done through the can openings.
