Retrofit fluorescent light tube fixture apparatus of this invention includes a metal reflector of an inverted wave shape and fluorescent light tubes, attached to sockets, mounted in the troughs of the inverted wave shape, and a formed plastic having the same contour as the inverted wave shape, and the formed plastic fitting intimately on the back of the reflectors to be a sub-assembly, and this subassembly fitting onto a ceiling mount channel wherein side walls of the ceiling mount channel fitting into slots in sidewalls of the formed plastic backing, and the side walls of the formed plastic backing attached to live plastic hinges also attached to the formed plastic backing. Preferred material for the formed plastic backing is a rigid polyvinylchloride (PVC), and flexible PVC for the live plastic hinge. The live plastic hinge allows drop down of either side of the fixture apparatus without de-mounting from the ceiling mount channel.
