IC Rated Downlights : What you need to know
FAQ's about IC Ratings
What does IC-4 mean in lighting?
IC-4 indicates that a downlight can be completely covered by insulation and building materials without risk of overheating or fire.
Can IC-4 downlights be covered with insulation?
Yes, IC-4 rated fittings are designed to be fully covered by insulation and building elements like timber joists and plasterboard.
What’s the difference between IC and IC-F?
IC-F is similar to IC but tested for flammable insulation materials, making it suitable for modern insulation types.
Why choose IC-4 over CA90?
IC-4 allows full coverage with insulation, while CA90 requires a 90 mm clearance above the fitting, reducing thermal efficiency.
Are IC-4 downlights energy-efficient?
Yes, IC-4 rated fittings help maintain the building’s thermal envelope, improving energy efficiency.
