How to insulate recessed lighting?

•    Examine your recessed lighting fixture. If it is older, check and make sure any insulation if at all present, is three inches away from the lighting. If its insulation is any closer, your light could overheat. If you see no insulation, consider insulating your recessed light.
•    Check and see if there’s a fire resistant wallboard which surrounds your recessed lighting fixture. If this box is present, be sure the box is big enough and allow for 3 inches of space near the light, so the possibility of overheating is less. If you find no box, again consider insulating your recessed light.
•    Install a metal cylinder which acts as a dam should you choose to finally insulate your recessed light fixture using loose fill insulation. This cylinder will serve a double purpose - containing the insulation and keeping this insulation the necessary distance away from your lighting.
•    Replace the recessed lighting fixture with an "IC rated" one which is air tight and does not face the possibility of overheating. The recessed lights are easier to insulate as well.
•    Consider recessed lighting fixtures which have "sealed use" CFL bulbs, because these bulbs are not only energy-saving, but also cooler and less hard to insulate.
