Here are 4 common LED track rail systems used in commercial lighting.
• 2-wire track rail
• 3-wire track rail
• 4-wire track rail
• 6-wire track rail
2-wire and 3-wire rails are usually used for simple LED track lighting systems.
4-wire rail features 3 circuits, stronger aluminum structure, and supports more LED track lights on the same rail.
6-wire rail adds signal wires for smart lighting control systems such as DALI, 0/1-10V, and DMX.
Choose the right track rail system based on lighting control method, load capacity, and project budget.
