Since I am still new to lighting, I hesitate to give my opinions.
But I have wondered all along why the transformers have the taps up to 15 or 16 volts and don't have two or three 12v taps instead. According to Stephen, my idea apparently wasn't so stupid.
And will the transformers change in this way when LEDs become dominant?
