Hiwassee Dam and powerhouse. This plant is in a remote location and has relatively few visitors. The reception is correspondingly small. Its scheme of lighting may be noted. The round holes in the ceiling conceal "downlight" units which concentrate strong direct light on persons and objects from invisible sources. Background lighting is supplied from tubular units laid in coves along two sides of the room which throw light chiefly on the upper part of the walls and the light colored portion of the ceiling. Visible light fixtures are combined with air conditioning outlets and are decorative only. A large window along the left side of the room permits observation of the control room
