Abstract
A universal housing can assembly used as a component of a recessed downlight fixture and which can be utilized in both insulation contact (I.C.) and non-insulation contact (non-I.C.) applications. The preferred housing can is deep drawn of aluminum or other suitable materials and is configured to operate at or below thermal standards for I.C. applications and also for non-I.C. applications. The housing can assemblies formed according to the invention utilize thermal protective devices positioned within the assemblies to shut the fixture off or "cycle" the fixture in the event that predetermined thermal conditions are exceeded in either an I.C. or a non-I.C. application. According to the invention, a single can assembly can be used as and marked as both I.C. and non-I.C. housing cans.
