    Abstract: A swivel assembly (A) connects a lamp arm assembly (B) with a wall mounting (C). A lamp assembly (D) is supported by the lamp arm assembly. The swivel assembly includes a first swivel member (10), a second swivel member (20), and a third swivel member (30) each having an axial passage therethrough. A first end (42) of a first arm (40) is nonrotatably connected axially with the second swivel member. A linear region (46) of the first arm extends rotatably through the axial passage of the third swivel member. The first and third swivel members are connected with the wall mounting by threaded sleeves (96, 102). In this manner, the second swivel member and the attached arm which extends axially therefrom are able to be rotated selectively around the wall mounting.
