1. A birdstop closure for closing an aperture at the point of entry of a pipe into an opening in the rear of a luminaire headcasing, wherein the aperture has a generally annular planar shape defined by the outer surface of the pipe and the inner edge of the opening in the rear of the luminaire headcasing, the closure comprising
a generally annular body shaped complementary to the generally annular planar shape to cover and fit within the aperture, having a thickness, an outer periphery shaped complementary to the inner edge of the opening in the rear of the luminaire headcasing, and an inner periphery shaped complementary to the outer surface of the pipe; a bifurcation at a point along the inner and outer periphery of the body to enable the split opening thereof for placement thereof in abutting circumscribing relationship around the pipe; an abutment surface extending outwardly from the outer periphery of the body for abutment against the luminaire headcasing adjacent the aperture; and a retainer mechanism across the bifurcation for securement of the closure in situ around the pipe.
