Mid century modern scandinavian brass pendant lamp model Multi-lite by Louis Weisdorf

Mid century modern scandinavian brass pendant lamp model Multi-lite by  Louis Weisdorf.  The core of the multi-lite is a two-cylinder form that would work as a shade on its own but is additionally encompassed by a large metal ring anchoring two quarter-spherical shells. The shells can be individually rotated to create multiple arrangement combinations. It is compatible with US or EU bulbs, E27.
