A couple of on-line catalogs that feature a very wide selection of light fixtures:
Classic style boutique lights:
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)
