ABSTRACT:
A light fixture collapsible for shipping has rotatable and axially-displaceable arms that are resiliently urged toward a central body such that when the arms are re-aligned with the body upon unpacking the fixture, the resilient means urges a positioning pin to lock the arm in place. The fixture has a hollow body with a peripheral wall against which a plurality of arms are to extend radially outward. A post on one of the arm and the body extends into the other of the arm and the body, making the arms rotatable about their axes. A positioning pin on the arm and a hole in the body, or vice versa, engage when the arm is in alignment. A helical spring urges the arm toward the body.
