I discuss current understanding of the evolutionary state of these objects, the role duplicity may play and known physical characteristics of these stars using the X-ray luminous LBVs Eta Carinae and HD 5980 as test cases.to appear in the Proceedings of "Massive Stars: Fundamental Parameters and Circumstellar Interactions"Astrophysicstext
