This project was completed about 12 years ago so the lighting is no longer available. You can achieve the same effect with many of the track or linear lighting brands out on the market today. The key is to get enough extra length so you can curl it around like this. The tube the holds the wire is very flexible so you can come up with lots of different shapes. This Tech Lighting Mono-rail will give a similar look. http://www.techlighting.com/Products/Fixtures/Monorail/Casual-Rail-Kit-5-Head

You're welcome! Glad you like the look. I think it's pretty timeless and works in traditionally styled spaces like this one in addition to contemporary spaces.
