placing a first housing on a first t-grid and a second t-grid, wherein said first and second t-grids each have a block-shaped top, wherein said first housing has a first side having a mounting extension and a recessed indentation and a second side having a recessed indentation opposite the mounting extension of said first side and a mounting extension opposite said recessed indentation of said first side, wherein said mounting extension of said first side of said housing extends over said block-shaped top of said first t-grid, wherein said mounting extension of said second side extends over said block-shaped top of said second t-grid;

placing a second housing on a second t-grid and a third t-grid, wherein said second and third t-grids each have a block-shaped top, wherein said second housing has a first side having a mounting extension and a recessed indentation and a second side having a recessed indentation opposite the mounting extension of the first side and a mounting extension opposite said recessed indentation of said first side, wherein said mounting extension of said first side of said housing extends over said block-shaped top of said second t-grid, wherein said mounting extension of said second side extends over said block-shaped top of said third t-grid.

2. The method of claim 1 , wherein said first and second housings have clips attached to said mounting extensions, wherein the method further comprises the step of attaching said clips to said block-shaped tops of said first and second housings.

3. The method of claim 2 , wherein said first, second, and third t-grids each further comprise a thin middle portion and a base, wherein said method further comprises the step of placing a ceiling tile on said bases of said first and second t-grids adjacent to said first housing such that said ceiling tile is capable of keeping said first housing in place against a wall.

4. The method of claim 3 further comprising the step of placing a ceiling tile on said bases of said second and third t-grids adjacent to said second housing such that said ceiling tile is capable of keeping said second housing in place against a wall.

5. The method of claim 1 , wherein said first housing has at least one opening on its top and contains a ballast, wherein electrical wiring connects from an outside electrical source to said ballast, wherein said ballast provides electricity for a lamp within said housing.

6. A method of mounting at least one housing a recessed troffer luminaire in a t-grid ceiling, comprising:

placing a first housing adjacent a first t-grid and a second t-grid, wherein said housing has a first side, a second side opposite said first side, a mounting extension and a recessed indentation on said first side and on said second side, wherein said second side has a recessed indentation opposite said mounting extension of said first side and a mounting extension opposite said recessed indentation of said first side;

positioning said mounting extension of said first side of said first housing over said first t-grid, wherein said mounting extension of said second side extends over said second t-grid.

7. The method of mounting a plurality of housings for a recessed troffer luminaire in a t-grid ceiling of claim 6 further comprising:

placing a second housing adjacent said second t-grid and a third t-grid, wherein said second housing has a first side having a mounting extension and a recessed indentation and a second side having a recessed indentation opposite the mounting extension of the first side and a mounting extension opposite said recessed indentation of said first side, wherein said mounting extension of said first side of said second housing extends over said second t-grid and wherein said mounting extension of said second side of said second housing extends over said third t-grid.
