A luminaire assembly has an array of six luminaires mounted at the top of a high pole, and each of the luminaires has a preselected asymmetrical lighting pattern that is rotatably controllable by rotation of a lower optical assembly mounted on an upper main support housing. Rotation indexing mass on the assembly and housing indicate the relative position of the assembly to the housing to enable simply accomplished rotatable alignment of the overall lighting pattern.
