Abstract: A low voltage track lighting construction in which the transformer is mounted within a housing carried by an elongated track for adjustable movement therealong. A vertically oriented cylindrical member is relatively rotationally adjustable with respect to the housing and depends therefrom. The cylindrical member has a pair of oppositely disposed sockets. Engaging the cylindrical member are a pair of corresponding plugs, each plug supporting a vertically oriented rod section which may be effectively lengthened by engagement with additional sections. Slidably positioned on the rods are a second pair of plug elements, the inner ends of which engage corresponding parts of a lamp holding element to enable the lamp carrying element to be supported for pivotal movement about a horizontal axis. Additionally, the lamp holding element is capable of adjustment along a vertical axis and rotation about the same vertical axis.
