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.

1. A light assembly comprising:a light fixture adapted to be positioned relative to an opening defined in a surface of a structure, and further adapted to allow light to be projected through said opening; and a housing substantially enclosing said light fixture, said housing and said light fixture forming a preassembled integral unit, said housing including at least one generally fire-resistant material, said at least one generally fire-resistant material forming a substantially continuous surface with said surface of said structure. 2. A light assembly according to claim 1, whereinsaid structure includes a floor-ceiling assembly, said floor-ceiling assembly has a fire rating, and said housing is capable of substantially maintaining said fire rating after said light assembly is installed. 3. A light assembly according to claim 1, whereinsaid housing includes a bottom wall and another wall, a portion of said bottom wall extending beyond an intersection of said bottom wall and said another wall of said housing, said portion having upper and lower surfaces and a junction box positioned on said upper surface of said portion. 4. A light assembly according to claim 3, whereina gasket is positioned between said bottom wall and said surface of said structure. 5. A light assembly according to claim 1, whereinsaid at least one generally fire resistant material is selected from the group consisting of dry wall, plaster, and combinations thereof. 6. A light assembly according to claim 1, whereinsaid housing further including a support structure formed from aluminum. 7. A light assembly according to claim 6, whereinsaid support structure is mechanically coupled to said at least one generally fire resistant material and said light fixture. 8. A light assembly according to claim 6, whereinsaid support structure defines an interior surface facing said light fixture and an exterior surface, substantially all of said at least one generally fire resistant material being located adjacent said exterior surface. 9. A light assembly according to claim 8, whereinsaid support structure includes a metallic enclosure. 10. A light assembly according to claim 1, further comprisinga junction box adapted to be electrically connected to said light fixture. 11. A light assembly according to claim 10, further comprisingat least one conduit extending from said junction box, and being capable of electrically coupling said light fixture to at least one other light fixture. 12. A light assembly according to claim 10, whereinsaid junction box is located within said housing. 13. A light assembly according to claim 1, further comprisingan attachment member connected to said housing, and being configured to attach said light assembly to said structure. 14. A light assembly according to claim 13, whereinsaid attachment member includes a bar hanger. 15. A light assembly according to claim 1, whereinsaid housing is substantially cylindrical. 16. A method of installing a light assembly comprising the steps offorming a preassembled integral light unit including a lamp fixture and a housing substantially surrounding the lamp fixture, the housing including a generally fire-resistant material, and installing the integral light unit behind an opening in a surface of an adjacent structure, the housing forming a substantially continuous surface with the surface of the adjacent structure. 17. A method according to claim 16, whereinthe forming step includes forming the preassembled integral light unit to include a support structure having an exterior surface and an interior surface. 18. A method according to claim 17, whereinthe forming step includes forming the preassembled integral light unit so that the generally fire-resistant material is adjacent the exterior surface of the support structure. 19. A method according to claim 18, whereinthe forming step includes forming a substantially cylindrical preassembled integral light unit. 20. A recessed light fixture comprising:a light fixture adapted to be installed behind a surface of an adjacent structure; and a housing substantially surrounding said light fixture, such that said housing and said light fixture form a preassembled integral unit, said housing including a first and a second layer, at least one of said first layer and said second layer being formed from a generally fire-resistant material, and at least one of said first layer and said second layer being adapted to form a substantially continuous surface with the surface of the adjacent structure when installed therebehind. 21. A recessed light fixture according to claim 20, whereinsaid first layer forms an interior layer and said second layer forms an exterior layer. 22. A recessed light fixture according to claim 21, whereinsaid first layer is formed from aluminum. 23. A recessed light fixture according to claim 21, whereinsaid fire-resistant material is said second layer. 24. A recessed light fixture according to claim 23, whereinsaid first layer is formed from aluminum. 25. A light assembly comprising:a light housing; a recessed lighting fixture within said light housing; a fire resistant housing surrounding said light housing, said fire resistant housing having a plurality of side walls, a top wall, and a bottom wall, said bottom wall having an opening adapted to receive a portion of said light housing, wherein said fire resistant housing and said light housing form a pre-assembled integral unit and each of said side walls and said top wall of said fire resistant housing include a generally fire resistant material; and a gasket on said bottom wall of said fire resistant housing, said gasket having a hole therein that substantially aligns with said opening in said bottom wall. 26. A light assembly according to claim 25, whereinsaid light housing has an enclosed top, an open bottom, and reflective sides therebetween. 27. A light assembly according to claim 26, whereinsaid reflective sides are substantially cylindrical between said enclosed top and said open bottom. 28. A light assembly according to claim 25, whereinsaid generally fire resistant material is supported by a metal structure. 29. A light assembly according to claim 28, whereinsaid metal structure is aluminum. 30. A light assembly according to claim 25, whereinsaid fire resistant housing is generally rectangularly shaped. 31. A light assembly according to claim 25, whereinsaid fire resistant housing is generally cube-shaped. 32. A light assembly according to claim 25, whereinsaid gasket is formed from fiberglass. 33.
