A lamp assembly is disclosed which includes a base, a lamp arm mounting adapter on the base for pivotally mounting a lamp arm thereto, with the lamp arm itself having a first pair of hollow support tubes mounted on the adapter for pivotal movement on a vertical axis in a generally horizontal plane and having a arm support pivotally mounted on their opposite ends for pivotal movement on a vertical axis on a horizontal plane. A second pair of arms having inner and outer ends are pivotally mounted on their inner ends to the arm support for pivotal movement about a horizontal axis in a vertical plane. A counterbalance spring is connected between the arm support and the second pair of arms and a lamp head is pivotally connected on the outer end of the second pair of arms for pivotal movement at least about a horizontal axis in a vertical plane.
