A mast arm assembly supports a electrical light fixture to mounting pole. The mast arm assembly includes an elongate generally tubular mast arm having a first end for supporting the fixture and an opposed second end for mounting to the mounting pole. A first mounting bracket is welded to the mast arm at an intermediate location to provide temporary support of the mast arm to the mounting pole. A second mounting bracket is welded to the mast arm adjacent one end to enable the mast arm to be permanently secured to the pole. The mast arm includes a pair of diametrically opposed outwardly extending longitudinal ribs. The ribs provide a weldment surface for welding the first and second mounting brackets to the mast arm.
