I am installing wiring for an addition. The owner provided all the lighting. I usually install IC rated airtight lights, but he provided me with LED Non IC housings. I know you cannot use them on the upper floors where they poke through to the attic, or wherever there is insulation. But are they OK to use on the 1st floor ceilings where there is no insulation? Or does the energy code noot allow non-IC fixtures?
