At least one lighting module is selected from at least one track lighting module and/or at least one non-track lighting module. The at least one lighting zone extends along a first length dimension of the housing segment and including at least one first passage to receive the at least one track lighting module and/or non-track lighting module. The housing segment includes a first power supply segment to be coupled with a designated line voltage outlet to deliver line voltage power to the at least one lighting module in the at least one lighting zone. Each track lighting module includes a lighting subzone, with a second passage to receive one or more lighting submodules along a second length dimension. A second power supply segment is provided to couple with the first power supply segment to receive line power and to deliver low voltage to the one or more lighting submodules.
