Hi, Hoping someone can help. to wire up a LED Dimming Downlight you need both 240v and a dimming circuit. I will not be doing this myself but more to understand, will both the power circuit and dimming circuit interface with c-bus, guessing a 240v relay for power and a potentiometer interface. or when the potentiometer is on 0V the transformer turns the lights off completely. Cheers Brendan
