Abstract
A lighting system having a LED downlight in a ceiling fixture can be attached to a ceiling by fixing hanger bars to ceiling rafters. The lighting system can then be completely covered by insulation. The insulation thereby lays directly on the downlight, junction box, and a cup passing mains power from the junction box to the downlight. The insulation does not enter the cup, downlight, or junction box. The lighting system does not ignite or melt the insulation in normal operation if the insulation meets residential and commercial safety standards. In normal operation the lighting system does not expose the lighting system to a temperature exceeding 90 degrees Celsius. A trim can be attached to the downlight to change its appearance and without rendering the lighting system unsafe.
