Methods and apparatus for customization of a workspace, including lighting in the workspace. Multiple LED-based lighting units arranged in a personal workspace may be conveniently controlled by an occupant of the workspace to customize or personalize workspace lighting. Workspace customization, including lighting conditions, further is facilitated by various power distribution schemes to allow convenient access to power in the workspace for lighting units and other electronic devices. Workspace dividers, partitions and walls may be particularly configured to accommodate power distribution systems and various components of networked lighting systems in the workspace environment.
