In an embodiment of a light fixture support assembly for securing a light fixture to a fixed surface, the assembly includes a fixture-support member and a surface-attachment member. The fixture-support member has proximal and distal ends and also includes walls defining a compartment and further defining a first opening at the proximal end of the fixture-support member for communication with the surface-attachment member. The walls further define a second opening for communication with the light fixture. The fixture-support assembly also has a neck portion extending from the proximal end and the neck portion has a flange portion extending from it. The surface-attachment member includes a proximal end attached to the fixed surface and a distal end configured to engage the neck portion, whereby the fixture-support member is supported by the surface-attachment member when the neck portion is inserted into the fixture-support member.
