What do the 4 and 6 lines of the track groove in the track light refer to respectively?
4-Line (or 3-Circuit) Track Systems
A 4-line track typically corresponds to a 3-circuit track system. In this configuration, there are three live conductors, each corresponding to a separate circuit, plus one shared neutral conductor. This setup allows fixtures on the track to be divided into three independently controllable groups. Users can switch on and off or dim lights in each group separately, which is particularly useful in retail, gallery, and exhibition spaces where different lighting scenes are required. It offers great flexibility in lighting design and control.
6-Line (or Multi-Circuit) DALI Track Systems
A 6-line track system goes beyond the 3-circuit system by offering additional circuits for even more control over the lighting fixtures. While less common than the 4-line system, a 6-line system might include additional neutral lines or even dedicated lines for smart lighting controls or emergency lighting circuits. This type of system is used in more complex lighting setups where varied lighting scenarios are needed, or where fixtures with different voltage requirements must coexist on the same track.
