Top Rated 4 Inch Slim LED Downlight with Junction Box ✅ IC RATED - Sunco's slim LED downlights are IC rated, meaning the junction box is thermally protected and designed to be installed in the ceiling surrounded by insulation. Worry free installation, our retrofits won't overheat and cause a fire in the roof or overhead joist space. ✅ SIMPLE INSTALL - Sunco's LED slim downlights come equipped with a junction box which means they do not need a can.
