ABSTRACT:
A recessed lighting fixture includes a back housing which is secured to a form board for receiving poured concrete such that the concrete sets around the housing to form a recessed area in a concrete structure. The form board is joined to a stiffener plate to support the housing under the force of the concrete. The form board and stiffener plate are removed from the back housing and the internal components of the lighting fixture are disposed in and secured to the interior of the back housing to form a recessed lighting fixture which is flush with the surface of the structure, for example a concrete wall. The internal components of the fixture may subsequently be removed and replaced should the need arise as only the back housing is fixed to the concrete wall.
