Abstract: A frame for supporting a light fixture has regions of its sidewall corners that are double walled and secured with at least one mechanical-fastener (e.g., a rivet) at each such region of the sidewall corners. This results in a stronger frame that is able to support heavier loads as compared to a frame without such reinforced corner regions. The frame also has holes on its largest-planar-member for attaching to I-brackets and the I-brackets may be attached to a light-fixture-can of the light fixture. The frame also has different holes, on opposing sidewalls, that may be attached to a junction-box that covers over a largest-hole of the frame. Each I-bracket has a concave-surface for concentrically pressing up against an exterior surface of the light-fixture-can. Each I-bracket may attached to the light-fixture-can and to the frame. The I-brackets permit a height of the light-fixture-can to be set at different heights.

Abstract: An overall-assembly of a downlight, with a flangeless trim, and a spackle-frame have complementary structures for repeatably attaching or detaching the downlight to the spackle-frame merely by pushing the downlight into a central hole of the spackle-frame and without use of any external / separate tools. The flangeless trim has some upward protruding members that are configured to removably attached / detached to clips and housings-for-clips. The clips are housed within the housings-for-clips. And the clips and the housings-for-clips are retained in structures of the spackle-frame. The spackle-frame would typically be permanently installed within an appropriately sized hole in drywall (or the like), such as, but not limited to, ceiling drywall. In this way, such downlights may be readily installed or removed and all without use of external / separate tools.
