1-phase vs. 3-phase - what do I need?
1-phase is sufficient whenever all spotlights should be switched on/off together. One circuit in the track, one switch for everything - simple and cheap. You need 3-phase only when you want to dim or switch three lighting scenes separately (e.g. base + accent + wall wash). In living spaces 1-phase is usually the right choice, in retail often 3-phase.
