   I seem to recall that somebody does make an air-tight can light.  Or at least that they claim it's airtight.  I'll get back to youif I find one, but you might check at oikos.com, buildinggreen.com, or http://www.eeba.org.  Good luck, and let me know if you find one that works!

   The Lithonia 'cans' I used in my house (33 of 'em) are "almost" airtight, and they were inexpensive (but with the trim kits, the best looking ones I've ever seen).  All it took to make them airtight was a couple of pieces of metal tape (from an HVAC house) over the armored-cable entry and a 'clip' that was made in the housing to temporarily hold the light socket.  I I just caulked the joint where they penetrated the drywall.  Covered the whole thing with 12" of cellulose.

   I've got 8 recessed lights in my own ceiling and they must be pretty air tight cause the house tested out at 0.07 air changes/hour  ("tight" is considered to be 0.25 to 0.33.)

   They were name-brand stuff at Home Depot.  Maybe $50 each.  IC-rated and the solid metal on the bottom comes with a gasket so the drywall compress the gasket to the metal.

   Juno makes a recessed light called the Air-loc ready housing. When used with the Air-loc trims or an Air-loc gasket they are supposed to be pretty air tight. I don't know what the actual leakage might be, but they are certainly much tighter than most.
