A mounting system for an outdoor lighting unit including a pipe member located underground in an approximate vertical orientation and an electrical connection box mounted in an upper end of the pipe member and having an uppe r portion presenting an upper surface on which a standard of the lighting unit is supported. The relation between the upper portion of the connection box and the pipe member is such that in mounting the connection box in the pipe universa l movement is achieved prior to fixing the connection box against movement in order that the upper surface is positioned to ensure the standard of the light is vertical regardless of the fact the pipe member deviates from an exact vertical orientation. |
