A recessed light fixture has a plurality of fasteners for securing a can or top hat of the recessed light fixture to a substrate, e.g., sheetrock ceiling and/or open frame mounting plate. Each of the plurality of fasteners comprise a clevis bracket, a clevis hook having perpendicular tabs that rotatably attach the clevis hook to the clevis bracket. When the recessed light fixture is inserted into an opening of the substrate, the clevis hooks rotate out of the way into slots in a wall of the recessed light fixture can. Once the clevis hooks clear the substrate, the clevis hooks rotate back through the wall of the recessed light fixture can. Then the clevis brackets are slideably moved toward the substrate, whereby gripping portions of the clevis hooks will engage the substrate and thereby hold the recessed light fixture to the substrate.

1. An apparatus for securing a recessed light fixture to a substrate, comprising: a plurality of fastening assemblies, each of the plurality of fastening assembles comprising a clevis bracket, anda clevis hook having tabs perpendicular to and at a proximal end thereof,wherein the tabs are rotateably
1. An apparatus for securing a recessed light fixture to a substrate, comprising: a plurality of fastening assemblies, each of the plurality of fastening assembles comprising a clevis bracket, anda clevis hook having tabs perpendicular to and at a proximal end thereof,wherein the tabs are rotateably attached to a proximal end of the clevis bracket;a can, the can comprising a tubular shaped wall,a flange attached to a proximal end of the tubular shaped wall and substantially perpendicular thereto, andslots adapted to allow each of a gripping portion of the clevis hooks to pass therethrough; anda fastener for each of the clevis brackets, wherein the fasteners slideably couple the clevis brackets to the tubular shaped wall;wherein when the can passes through an opening in a substrate the clevis hooks are positioned axially to the tubular shaped wall until the clevis hooks clear the substrate,then the gripping portions of the clevis hooks pass through the slots in the tubular shaped wall of the can, andthe clevis brackets are slideably positioned along the tubular shaped wall toward the substrate so that the gripping portions of the clevis hooks engage a back face of the substrate while the flange engages a front face of the substrate, thereby holding the recessed light fixture in the substrate. 2. The apparatus according to claim 1, further comprising ridges on the clevis bracket for resisting bending thereof. 3. The apparatus according to claim 2, wherein the ridges are substantially perpendicular to a face of the clevis bracket for stiffening purposes thereof. 4. The apparatus according to claim 1, wherein the clevis hooks are U-shaped. 5. The apparatus according to claim 1, wherein rotation of the clevis hooks are limited so that clevis hooks remain substantially perpendicular to an external face of the tubular shaped wall upon engaging the substrate. 6. The apparatus according to claim 1, wherein the flange is coterminous with a face of the substrate when the gripping portions of the clevis hooks engage the substrate. 7. The apparatus according to claim 1, wherein the gripping portions of the clevis hooks have serrated ridges thereon. 8. The apparatus according to claim 1, wherein each of the fasteners comprise a bolt and a wing nut. 9. The apparatus according to claim 8, wherein the bolt fits inside of an elongated slot in the clevis bracket. 10. The apparatus according to claim 1, wherein the can is adapted for a light emitting diode (LED) module. 11. The apparatus according to claim 1, wherein the clevis bracket and clevis hook are made of metal. 12. The apparatus according to claim 1, wherein the can is made of metal. 13. The apparatus according to claim 1, wherein the substrate comprises a sheetrock ceiling. 14. The apparatus according to claim 13, wherein the substrate further comprises a an open frame mounting plate at a back face of the sheetrock ceiling. 15. The apparatus according to claim 1, wherein the opening in the substrate is from about five inches to about eight inches in diameter. 16. The apparatus according to claim 1, wherein the plurality of fastening assemblies are three fastening assemblies. 17. The apparatus according to claim 16, wherein the three fastening assemblies are equidistantly spaced apart. 18. The apparatus according to claim 16, wherein the three fastening assemblies are spaced at various distances so as to avoid obstructions. 19. A method for securing a recessed light fixture into a substrate, said method comprising the steps of: inserting a recessed light fixture can having a plurality of fastening assemblies into an opening in a substrate, each of the plurality of fastening assemblies comprises a clevis bracket and a clevis hook, wherein the clevis hook is rotatably attached to a proximal end of the clevis bracket;rotating the clevis hooks to a substantially parallel orientation within a wall of the recessed light fixture can so that the clevis hooks pass through and beyond the opening in the substrate;stopping travel of the recessed light fixture can into the opening in the substrate when a flange attached to a proximal end of the recessed light fixture can that is coterminous with a face of the substrate;moving the clevis brackets slideably toward the substrate until gripping portions of the clevis hooks engage an edge of the opening at the substrate; andlocking the clevis brackets to the wall of the recessed light fixture can, thereby holding the recessed light fixture can in the substrate. 20. The method according to claim 19, wherein the step of moving the clevis brackets slideably toward the substrate include the step of rotating the clevis hooks out through slots in the wall of the recessed light fixture can so that the gripping portions of the clevis hooks will engage the edge of the opening in the substrate. 21. The method according to claim 19, wherein the step of locking the clevis brackets to the wall of the recessed light fixture can comprise the step of tightening bolts and wing nuts to secure the clevis brackets to the wall.
