Should I use a Single Circuit track system or Double Circuit track system? Why?
The double circuit track system can separate all light fixtures (spotlights, glass pendants, accent lights, etc.) on the same track to TWO groups and controlled by TWO switches.
For example, you can have two groups of track lights on the same track. One group of track lights is for the wall washing purpose, another group for general lighting purposely. You can then turn them one and off individually as you need.
