As you know, there are are four elements of illumination: Accent (highlighting objects), ambient (uplighting), decorative (visual jewelry like chandeliers) and task lighting.
Task lighting provides the main illumination for a space. Typically track and recessed lighting provide this function. Recessed has been the preferred application, because track has been bulky, boring and cumbersome.

Track, especially rail has been reinvented with a slimmer profile and literally 1000's of options for pendants and heads.
