Miboxer Stair Light Sub-device (Dual White Controller) *must be used with Stair Light Master

The Miboxer BS-L2C is a dual-white (CCT) expansion module for the BS64 stair light master, adding one more controlled step to an existing PLC stair-lighting run. It is not a standalone controller and must be wired to a BS64 master; it is the standard way to extend step count or add tunable-white control to individual steps without introducing a second, incompatible control system. Confirm wiring and step count against the BS64 installation guide.
