A cove lighting system includes a plurality of cove extrusions and a plurality of mounting brackets. Each cove extrusion is a single extrusion defining a cove channel and mounting features. The mounting brackets are attached to the wall and the cove extrusions are hung from the mounting brackets with the mounting features. The cove extrusions are hung immediately adjacent to each other to define a continuous cove channel to receive one or more power boxes, and one or more luminaires.
