I recently asked my electrician to replace all of the non-IC cans he installed, on the top floor of my house, with air tight ones (20 in all). Once he completed the job I noticed that all of the cans were for r30 bulbs. I had r40 bulbs, so they are all protruding about 1/4 in. All of the lights are 60 watt halogens. Other than the way they look, is there anything to be concerned about? I don’t believe there are any IC r40 cans on the market. So, I am considering having him change all of them back to the non-IC and just put an insulated barrier around each one in the attic.

Any advice would be greatly appreciated.

One additional piece of info... I am planning on adding insulation to my attic and would have like to be able to cover the cans.

Look inside the can, there shgould be a label that has all of the acceptable trims, lamp type & wattage combinations. If an R40 lamp is not one of the listed lamps, my advice would be not to use the lamp & change to one of the lamps that is listed on the label.

Thanks for your reply. The can calls for an r30. However, an r30 looks very small in the 6inch can. Also, it appears to produce less light than the r40. I think my only option is to put the original non-ic r40 cans back in. Not something I wanted to do.
