Product review (4 stars): the lower light is fine but it you are hoping for more light consider ...
I would give it a 5 Star rating except that it is not very bright.  In my application, an under cabinet light in my powder room, the lower light is fine but it you are hoping for more light consider another light.  This one was easy to pin up.  We wired it into a wall switch.  It also has the capability to connect to additional sections so could span several cabinets.
