This integrated LED Hampton Bay Linear Track Lighting kit comes with everything you need to get up and running. It provides an abundance of light and sophistication to your interior space. It features multi-directional lamp heads to provide light to difficult places where light does not reach. You can add additional heads, connect multiple kits together (coupler sold separately) using only 1 power supply or create design patterns with additional track lighting components (sold separately). The power supply can be attached anywhere along the track and the entire system is ceiling or wall mountable.
