The light fixture can also include a baffle removably coupled to the housing, where the baffle includes at least one baffle wall having an outer surface, where the outer surface of the at least one baffle wall has at least one housing coupling feature disposed thereon. The baffle can be coupled to the housing and decoupled from the housing without use of tools. ## Claims ### Claim 1 A light fixture comprising: a housing comprising at least one housing wall having an inner surface that forms a cavity, wherein the inner surface of the at least one housing wall has at least one baffle coupling feature disposed thereon, wherein the at least one baffle coupling feature comprises at least one slot disposed within the inner surface of the at least one housing wall; and a baffle removably coupled to the housing, wherein the baffle comprises at least one baffle wall having an outer surface, wherein the outer surface of the at least one baffle wall has at least one housing coupling feature disposed thereon, wherein the at least one housing coupling feature comprises at least one tab that extends outward from the outer surface of the baffle wall, wherein the baffle is coupled to the housing by inserting the at least one tab into an opening of the at least one slot and rotating the baffle in a first direction, and wherein the baffle is decoupled from the housing by rotating the baffle in a second direction opposite the first direction and removing the at least one tab from the opening of the at least one slot. ### Claim 2 (depends on 1) The light fixture of claim 1, wherein the at least one tab comprises a first tab and a second tab, and wherein the at least one slot comprises a first slot and a second slot. ### Claim 3 (depends on 2) The light fixture of claim 2, wherein the first tab and the second tab are offset relative to each other around the baffle. ### Claim 4 (depends on 2) The light fixture of claim 2, wherein the first slot and the second slot have a spiral shape. ### Claim 5 (depends on 4) The light fixture of claim 4, wherein the first slot and the second slot accommodate less than a half turn of the baffle. ### Claim 6 (depends on 2) The light fixture of claim 2, wherein the first slot and the second slot further comprise a detent disposed opposite the opening. ### Claim 7 (depends on 1) The light fixture of claim 1, wherein the inner surface of the at least one housing wall, when viewed from below, is conical, and wherein the outer surface of the at least one baffle wall, when viewed from above, is conical. ### Claim 8 (depends on 1) The light fixture of claim 1, wherein a distal edge of the baffle is substantially flush with a trim that extends from a distal end of the at least one housing wall when the baffle is coupled to the housing. ### Claim 9 (depends on 8) The light fixture of claim 8, wherein the distal end of the at least one housing wall comprises a recess for receiving the baffle when the baffle is coupled to the housing. ### Claim 10 A baffle for a light fixture, the baffle comprising: at least one wall having an inner baffle surface and an outer baffle surface, wherein the inner baffle surface is configured to control effects of light emitted by the light fixture; and at least one housing coupling feature disposed on the outer baffle surface of the at least one wall, wherein the at least one housing coupling feature comprises at least one tab that extends outward from the outer baffle surface of the at least one wall, wherein the at least one housing coupling feature is configured to detachably couple to at least one baffle coupling feature disposed on an inner housing surface of a housing of the light fixture, wherein the at least one baffle coupling feature comprises at least one slot disposed on the inner housing surface of the housing, wherein the at least one tab couples to the at least one slot by being inserted into an opening of the at least one slot and being rotated in a first direction, wherein the at least one housing coupling feature is further configured to decouple from the at least one baffle coupling feature by rotating the at least one tab in a second direction that opposes the first direction and removing the at least one tab from the opening of the at least one slot. ### Claim 11 (depends on 10) The baffle of claim 10, wherein the at least one tab comprises a first tab and a second tab. ### Claim 12 (depends on 11) The baffle of claim 11, wherein the first tab and the second tab are not spaced equidistantly from each other around the outer baffle surface. ### Claim 13 (depends on 11) The baffle of claim 11, wherein the first tab and the second tab are spaced equidistantly from each other around the outer baffle surface. ### Claim 14 (depends on 11) The baffle of claim 11, wherein the at least one tab comprises a structural support between a proximal end of the at least one tab and the outer surface of the at least one wall. ### Claim 15 (depends on 10) The baffle of claim 10, further comprising: an alignment feature disposed on the at least one wall, wherein the alignment feature is configured to properly align the at least one housing coupling feature relative to the at least one baffle coupling feature when the at least one housing coupling feature is about to couple to the at least one baffle coupling feature. ### Claim 16 (depends on 10) The baffle of claim 10, wherein the at least one tab is substantially parallel with a trim disposed at a distal end of the at least one wall. ### Claim 17 (depends on 10) The baffle of claim 10, wherein the at least one wall has a conical shape. ### Claim 18 A housing for a light fixture, the housing comprising: at least one wall having an inner surface, wherein the inner surface is configured to receive at least a portion of a baffle of the light fixture, wherein the inner surface of the at least one wall has disposed thereon at least one baffle coupling feature, wherein the at least one baffle coupling feature comprises at least one slot disposed within the inner surface of the at least one wall, wherein the at least one baffle coupling feature is configured to detachably couple to at least one housing coupling feature disposed on an outer surface of the baffle of the light fixture, wherein the at least one housing coupling feature comprises at least one tab that extends outward from the outer surface of the baffle, wherein the at least one slot couples to the at least one tab by receiving the at least one tab into an opening of the at least one slot and allowing movement of the at least one tab along the at least one slot in a first direction, wherein the at least one baffle coupling feature is further configured to decouple from the at least one housing coupling feature by allowing movement of the at least one tab in a second direction that opposes the first direction toward the opening of the at least one slot so that the at least one tab is removed from the opening. ### Claim 19 (depends on 18) The housing of claim 18, wherein the at least one slot comprises a detent disposed opposite the opening. ### Claim 20 (depends on 18) The housing of claim 18, wherein the at least one slot is up to ¼ of a circumference of the inner surface of the at least one wall.
