A light fixture comprising: a base comprising a sidewall extending between a first end and a second end to define an interior passageway, the first end defining an aperture; a light mount movably coupled to the base; and a mechanical actuator configured to direct movement of the light mount relative to the base, the mechanical actuator comprising: one or more first sliders coupled to the light mount; a first guide coupled to the base and comprising: first and second arcuate bearing surfaces that define an arcuate path along which movement of the light mount relative to the base is permitted, each of the arcuate bearing surfaces configured to support at least one of the first sliders; where a minimum distance between the first arcuate bearing surface and the second arcuate bearing surface increases along at least a majority of the first arcuate bearing surface; an input shaft; a carrier member movably coupled to the input shaft, the carrier member longitudinally movable relative to the input shaft; and a lever movably coupled to the carrier member and pivotally coupled to the base, the lever configured to move the first sliders along the arcuate bearing surfaces in response to movement of the carrier member relative to the input shaft; where movement of the first sliders along the arcuate bearing surfaces rotates the light mount relative to the base. a base comprising a sidewall extending between a first end and a second end to define an interior passageway, the first end defining an aperture; a light mount movably coupled to the base; and a mechanical actuator configured to direct movement of the light mount relative to the base, the mechanical actuator comprising: one or more first sliders coupled to the light mount; a first guide coupled to the base and comprising: first and second arcuate bearing surfaces that define an arcuate path along which movement of the light mount relative to the base is permitted, each of the arcuate bearing surfaces configured to support at least one of the first sliders; where a minimum distance between the first arcuate bearing surface and the second arcuate bearing surface increases along at least a majority of the first arcuate bearing surface; an input shaft; a carrier member movably coupled to the input shaft, the carrier member longitudinally movable relative to the input shaft; and a lever movably coupled to the carrier member and pivotally coupled to the base, the lever configured to move the first sliders along the arcuate bearing surfaces in response to movement of the carrier member relative to the input shaft; where movement of the first sliders along the arcuate bearing surfaces rotates the light mount relative to the base. a first guide coupled to the base and comprising: first and second arcuate bearing surfaces that define an arcuate path along which movement of the light mount relative to the base is permitted, each of the arcuate bearing surfaces configured to support at least one of the first sliders; where a minimum distance between the first arcuate bearing surface and the second arcuate bearing surface increases along at least a majority of the first arcuate bearing surface; first and second arcuate bearing surfaces that define an arcuate path along which movement of the light mount relative to the base is permitted, each of the arcuate bearing surfaces configured to support at least one of the first sliders; where a minimum distance between the first arcuate bearing surface and the second arcuate bearing surface increases along at least a majority of the first arcuate bearing surface; an input shaft; a carrier member movably coupled to the input shaft, the carrier member longitudinally movable relative to the input shaft; and a lever movably coupled to the carrier member and pivotally coupled to the base, the lever configured to move the first sliders along the arcuate bearing surfaces in response to movement of the carrier member relative to the input shaft; where movement of the first sliders along the arcuate bearing surfaces rotates the light mount relative to the base.
