A fire assembly that can be used for installing recessed electrical fixtures into various structures such as wall assemblies is provided. The fire assembly includes an electrical fixture contained within a generally fire-resistant housing. The housing can enclose the electrical fixture in such a manner that the resulting fire assembly has an integral structure. In some instances, a support structure can be utilized to attach the housing to the electrical fixture. Furthermore, the housing can be a cube-shaped box have a variety of generally fire-resistant walls. These walls can be made from materials such as sheet rock.

What is claimed is: 1. The fire-resistance-rated, floor-ceiling assembly having: a pre-assembled, fire-resistance-rated, recessed lighting assembly installed above a room and projecting light through an opening in said fire-resistance-rated floor-ceiling assembly into said room, wherein said fire-r
What is claimed is: 1. The fire-resistance-rated, floor-ceiling assembly having: a pre-assembled, fire-resistance-rated, recessed lighting assembly installed above a room and projecting light through an opening in said fire-resistance-rated floor-ceiling assembly into said room, wherein said fire-resistance-rated floor-ceiling assembly had an original fire resistance rating before said opening was made therein and exhibits (i) an upper surface facing an interior of said fire-resistance-rated floor-ceiling assembly, and (ii) a lower surface facing a room below said fire-resistance-rated floor-ceiling assembly, wherein fire resistance is determined by (i) exposing to fire for one hour in accordance with ASTM E119 (1999) in which a 48 inch by 48 inch small scale floor-ceiling assembly constructed with a joist cavity containing a recessed light assembly and an adjacent joist cavity without a recessed light assembly is so exposed and (ii) measuring air temperatures in the joist cavities, whereby a one hour fire resistance rating is achieved when temperature measurements in the joist cavity with an incandescent light fixture is no more than 5% hotter than temperatures measured in the adjacent joist cavity without said light fixture, said pre-assembled, fire-resistance-rated, recessed lighting assembly with a combination comprising: (a) a lamp socket configured to receive a lamp element and electrically communicating with an electrical junction box by wires extending from said lamp socket, (b) a light can that effectively surrounds said lamp socket and directs light from said lamp element downwardly through said opening in said fire-resistance-rated floor-ceiling assembly, (c) a fire resistant housing that effectively surrounds said light can, and (d) a gasket between said housing and said upper surface of said fire-resistance-rated floor-ceiling assembly and effectively surrounding the opening made in said fire-resistance-rated floor-ceiling assembly for said pre-assembled, fire-resistance-rated, recessed lighting assembly, wherein said pre-assembled, fire-resistance-rated, recessed lighting assembly maintains said original fire resistance rating of said fire-resistance-rated, floor-ceiling assembly before said opening was made therein for installing said pre-assembled, fire-resistance-rated, recessed lighting assembly therein. 2. The fire-resistance-rated, floor-ceiling assembly according to claim 1 wherein said electrical junction box is outside said fire resistant housing. 3. The fire-resistance-rated, floor-ceiling assembly according to claim 1 wherein fire resistant housing comprises aluminum walls. 4. The fire-resistance-rated, floor-ceiling assembly according to claim 1 wherein fire resistant housing is cube-shaped. 5. The fire-resistance-rated, floor-ceiling assembly according to claim 1 wherein wires from said lamp socket extend through said fire resistant housing into a junction box located outside said fire resistant housing. 6. The fire-resistance-rated, floor-ceiling assembly according to claim 1 wherein said can exhibits a generally cylindrical shape. 7. The fire-resistance-rated, floor-ceiling assembly according to claim 1 wherein fire resistant housing further comprises bar hangers to secure said pre-assembled, fire-resistance-rated, recessed lighting assembly between joists in said floor-ceiling assembly. 8. The fire-resistance-rated floor-ceiling assembly according to claim 1 comprising a pre-assembled, fire-resistance-rated, recessed lighting assembly installed therein and projecting light through an opening in said fire-resistance-rated floor-ceiling assembly, a combination comprising: (a) a recessed light fixture capable of distributing light, said fixture comprising a lamp socket and a reflector can for directing light from said lamp out of said fixture; and (b) a housing effectively enclosing said recessed light fixture and coupled thereto so that said recessed light fixture and said housing form a preassembled integral unit adapted for installation adjacent an opening made in said fire-resistance-rated floor-ceiling assembly for said recessed light fixture, said housing comprising (i) a generally fire-resistance material and (ii) a metallic support frame, and (c) a generally fire resistant gasket adapted to substantially surround the opening in the fire-resistance-rated floor-ceiling assembly through which said reflector can directs light from said lamp. 9. The fire-resistance-rated floor-ceiling assembly according to claim 8 wherein said pre-assembled, fire-resistance-rated, recessed lighting assembly maintains the fire resistance rating of said floor-ceiling assembly after installation of said lighting assembly therein. 10. The fire-resistance-rated floor-ceiling assembly according to claim 9 wherein said lighting assembly is capable of achieving a one hour fire resistance rating under ASTM E119 (1999). 11. The fire-resistance-rated floor-ceiling assembly according to claim 9 wherein said lighting assembly comprises a pre-assembled combination of (a) a lamp socket within (b) a reflector can effectively surrounded by (c) a generally fire resistant housing comprising (i) an aluminum support frame and (ii) top and side walls made from a generally fire resistant material with (d) a fire resistant gasket substantially covering a bottom surface of said assembly with an opening therein for light to be projected from said lighting assembly and engage a corresponding opening surface in a fire-resistance-rated floor-ceiling structure of a fire resistance rated structure.
