A recessed ceiling light fixture with spring biased retainer clips that retract flush or are biased away from the side of the can housing for installation is disclosed. The fixture includes a housing having a side wall, a top wall, and an open bottom. Two rigid retainer clips are mounted diametrically opposed on the housing. Each retainer clip has a mounting tab inside the housing extending into a leg that passes out of the housing, which leg is bent to form an elbow, which elbow extends to a strut passing back into the housing, wherein the mounting tab selectively engages the side wall to limit movement of the spring clip. A bolt and coiled spring create compliance and bias in the spring clip by passing loosely through a slotted opening in the top wall at one end and joining the mounting tab at the other end.

1. A recessed ceiling light fixture, comprising: a housing having a side wall, a top wall up on top, and an open bottom with a lip at the bottom;a plurality of openings in the side wall;at least one rigid retainer clip having a mounting tab inside the housing extending into a leg that passes through
1. A recessed ceiling light fixture, comprising: a housing having a side wall, a top wall up on top, and an open bottom with a lip at the bottom;a plurality of openings in the side wall;at least one rigid retainer clip having a mounting tab inside the housing extending into a leg that passes through one of the openings out of the housing, which leg is bent at a distal end to form an elbow, which elbow extends to a strut passing through one of the openings into the housing, wherein the mounting tab selectively engages an interior of the side wall;means for creating compliance extending loosely through a slotted opening in the top wall and connecting to the mounting tab, wherein the means for creating compliance simultaneously biases the leg to swing away from the side wall and downward toward the open bottom; andwherein the leg swing away from the side wall under spring bias is limited by at least one of the mounting tab engaging the side wall and the means for creating compliance engaging a lip of the slotted opening in the top wall. 2. The recessed ceiling light fixture of claim 1, wherein rigid retainer clip has a rigidity to support the weight of the recessed ceiling light fixture with minimal flexing. 3. The recessed ceiling light fixture of claim 1, wherein the leg includes a plank shape with a rib extending along a length thereof. 4. The recessed ceiling light fixture of claim 1, wherein the means for creating compliance includes a bolt and a coiled spring disposed around the shaft of the bolt, and wherein the bolt passes loosely through the slotted opening in the top wall at one end and is attached to the mounting tab at an opposite end. 5. The recessed ceiling light fixture of claim 4, wherein the bolt includes a bolt head at one end disposed outside of the housing and threads at an opposite end screwed into the mounting tab, and turning the bolt head changes the distance between the mounting tab and the top wall thereby changing the amount of force on the spring. 6. The recessed ceiling light fixture of claim 1, wherein the means for creating compliance includes a shaft extending from the mounting tab and passing loosely through the slotted opening in the top wall, and wherein a spring is disposed with the shaft to press against the top wall and the mounting tab. 7. The recessed ceiling light fixture of claim 1, wherein a distal end of the strut includes at least one of a hook, a bend, a T-shaped tip, and a tab having a hole therethrough. 8. The recessed ceiling light fixture of claim 1, wherein the interior of the housing includes mounting hardware. 9. The recessed ceiling light fixture of claim 1, wherein the plurality of openings in the side wall are T-shaped. 10. A recessed ceiling light fixture, comprising: a cylindrical housing having a side wall, a top wall up on top, and an open bottom with a lip at the bottom;a plurality of openings in the side wall;two retainer clips mounted diametrically opposed on the housing, each retainer clip having a mounting tab inside the housing extending into a leg that passes through one of the openings out of the housing, which leg is bent at a distal end to form an elbow, which elbow extends to a strut, wherein the mounting tab selectively engages an interior of the side wall;means for creating compliance passing loosely through a slotted opening in the top wall and joined to the retainer clip via the mounting tab, wherein the means for creating compliance simultaneously biases the leg to swing away from the side wall, and to translate the leg downward toward the open bottom; andwherein the leg swing motion away from the side wall is limited at least by the mounting tab bumping into the side wall. 11. The recessed ceiling light fixture of claim 10, wherein the means for creating compliance includes a bolt and a coiled spring disposed on the shaft of the bolt, and wherein the bolt passes loosely through the slotted opening in the top wall at one end and is attached to the mounting tab at an opposite end, and the spring is compressed therebetween, and wherein the bolt shaft freely pivots along the slot and translates through the slotted opening. 12. The recessed ceiling light fixture of claim 10, wherein a distal end of the strut passes through one of the openings into the housing, and the distal end further includes at least one of a hook, a bend, a T-shaped tip, and a tab having a hole therethrough. 13. The recessed ceiling light fixture of claim 11, wherein the slotted opening in top wall enables the bolt to freely swivel along the direction of the slot and to freely translate through the slot thereby creating compliance in the spring clip. 14. A recessed ceiling light fixture, comprising: a can shaped housing having a side wall, a top wall, and an open bottom with a lip at the bottom;a plurality of slots in the side wall;a plurality of retainer clips, each retainer clip having a mounting tab inside the housing extending into a leg that passes through one of the slots out of the housing, which leg is bent at a distal end to form an elbow, which elbow extends to a strut passing through one of the slots into the housing, wherein the mounting tab selectively engages an interior of the side wall;means for creating compliance passing loosely through an oversized opening in the top wall and connected to the mounting tab, wherein the means for creating compliance enables the retainer clip to have at most two degrees of freedom in movement of each leg; andwherein one of the degrees of freedom in the leg movement includes biasing the leg to pivot away from the side wall of the housing, which pivoting movement causes movement of the mounting tab and means for creating compliance such that at least one of the mounting tab and means for creating compliance selectively engages the side wall and top wall, respectively, thereby limiting the pivoting movement of the leg. 15. The recessed ceiling light fixture of claim 14, wherein the means for creating compliance includes a bolt having a bolt head at one end disposed outside of the housing and threads at an opposite end screwed into the mounting tab, and a spring disposed on the bolt, so turning the bolt head changes the distance between the mounting tab and the top wall thereby changing the amount of compression on the spring. 16. The recessed ceiling light fixture of claim 14, wherein the mounting tab includes a protruding surface that selectively engages the side wall to limit the pivoting movement of the leg. 17. The recessed ceiling light fixture of claim 16, wherein mounting tab includes a C shape with the top of the C receiving the threaded end of the bolt, and the bottom of the C having the protruding surface that selective engages the side wall to thereby limit the pivoting movement of the leg. 18. The recessed ceiling light fixture of claim 14, wherein the strut at a distal end thereof inside the housing includes a tip bent toward the open bottom. 19. The recessed ceiling light fixture of claim 14, wherein another of the two degrees of freedom includes linear translation of the leg under bias downward relative to the housing top and bottom, and wherein the means for creating compliance creates bias in the leg pivot and the bias in the leg translation simultaneously. 20. The recessed ceiling light fixture of claim 14, wherein the mounting tab, leg, elbow, and strut are formed in one integral piece of material for rigidity.
