A couple of on-line catalogs that feature a very wide selection of light fixtures:

         Recessed lights:

          Classic style boutique lights:

           Outdoor lighting:

           Lighting control systems:

                 (great for complex areas with lots of lights, complex landscape lighting projects, etc.)

                 (easier to install as a retrofit because it uses radio frequency to send control signals.

                                                 Unique, modern style may be inappropriate for traditional residences)

                 (commercial/office lighting controls- occupancy sensors, multi-zone timer functions)
