• a light fixture housing with a housing sidewall extending circumferentially around a movable lens, the light fixture housing forming an inner space including at least one light source for emitting light through the movable lens;
• the movable lens arranged on a light output side of the light fixture housing and movable along the housing sidewall relative to the at least one light source;
• a sealing element between the housing sidewall and the movable lens, wherein:
• the sealing element seals the inner space from an exterior outside the light fixture, and
• movement of the movable lens modifies a volume of a cavity formed in the housing on the light output side, the cavity being at least partially bounded by the movable lens and the sealing element on an inner side of the cavity and open to the exterior on the light output side;
• and
• at least one drainage element extending from the cavity through the housing sidewall for draining accumulated liquid from the cavity.
