Recessed luminaires not identified for contact with insulation must be kept at least what distance from combustibles?

Explanation:
The key idea is heat control around recessed luminaires. If a fixture isn’t rated for contact with insulation, it must not be pressed directly against insulating material or other combustibles. Instead, you leave a small air gap to let heat escape and prevent overheating. The code specifically requires a half-inch air space between a non-IC recessed luminaire and insulation (or combustibles) so the fixture isn’t in direct contact with heat sources. If you need to have insulation touching or around a fixture, you must use an IC-rated unit that’s listed for insulation contact. The other, larger clearances aren’t required for this scenario; they’d be unnecessary given the fixture’s non-IC rating.
