hi, follow-up question to help me understand; would another method (using the dimmable light example) be to have several sets of lights at different light intensities and using say a rotary knob pass current to each set of lights to get sort of a stepped change in light?

using the above method could a switch be turned, say 1/8th of the way on, to waste a minor amount of energy to ease the transition between steps?

thanks for the previous answer!
