ABSTRACT:
A spherical form twist lock globe holder which is mountable to a lamp post and necked globe which is mountable to the globe holder are provided. The globe holder and globe are twist locked together. When the globe is mounted to the globe holder, the globe and globe holder define a substantially complete sphere. The globe is generally in the shape of a truncated sphere and has a generally flat bottom surface. A neck extends from the bottom surface, and a flange with gaps extends radially from the end of the neck. The globe has a center, a globe radius, and a distance from the globe center to a bottom of the globe neck. The distance from the globe center to the bottom of the neck is smaller than the radius of the globe. The globe holder has an arcuate base, preferably defining a segment of a sphere. A collar extends upwardly from the globe holder base and receives the globe neck. At least one arm extends up from the globe holder base and a finger extends from the arm. The globe holder finger engages the globe neck flange to twist lock the globe to the globe holder.
