That's not even close to the reason why it's not happening. Your technical explanation of why it's hard doesn't hold water. Just have a trigger point ~30 seconds upstream and program into the Anchor Wall's PLC (yes, there's one at the base) to ramp a PWM profile for the light up, or down, on a timer. It might reach full brightness 3 seconds early - who cares.
As I have said before the reason why it is not happening is not technical in nature.
