I am looking for a pendant to put into track lighting. When I make "track lighting" part of my search, I still get all these other pendants that are hard wired into the ceiling! How can I sift through all that so that what my options are are ONLY fixtures that fit on a track???! Here's an example: http://www.houzz.com/photos/products/price--10-to-60/track-lighting-pendant/p/100
