A light fixture to be mounted within a hole in a wall or ceiling comprising: a housing having a main body portion smaller than the hole; a mounting clip; a mounting clip aperture in said main body portion, said mounting clip corresponding to and extending through said aperture; said mounting clip aperture including a vertical portion and a horizontal portion communicating therewith, wherein said horizontal portion is wider than said vertical portion; wherein said mounting clip includes a neck portion and an adjacent shoulder portion, wherein said neck portion is narrower than said vertical portion of said clip aperture and wherein said shoulder portion is narrower than said horizontal portion of said clip aperture but wider than said vertical portion of the clip aperture; said mounting clip being affixed to said housing at least at one point; said mounting clip being movable through said aperture between a first position and a second position, said first position corresponding to a pre-installation mode and said second position corresponding to an installed mode; said mounting clip including a first portion located on the outside of the housing and a second portion at least part of which is located within said housing when said clip is in said first position; wherein said mounting clip in said first position permits the housing to be inserted into the wall or ceiling hole; wherein said mounting clip in said second position is extended outward from said housing so that a maximum distance between an outer periphery which includes said mounting clip is larger than the hole, so that the mounting clip in said second position blocks withdrawal of the fixture from the wall or ceiling hole; wherein said mounting clip in said first position is accessible from the interior of the main housing and is movable through said aperture; said mounting clip aperture and mounting clip being configured to lock said mounting clip in said second position; and wherein in said second position, said neck portion of said mounting clip extends through said vertical portion of said aperture, said shoulder portion is located outside said housing, and said mounting clip urges said shoulder portion against said vertical portion, thereby to retain said mounting clip in said second position.
