Finally, this is optional, but if I can do it I want to add dawn/dusk effect such that when timer is ON

light intensity increases from 0 to 100% within 1-2 hr time frame
remains at maximum intensity for about 8 hours
dims gradually to 0% over 1-2 hr time frame.
Timer switches off

This is where I was considering the 2 types of Xitanium drivers but so far I am clueless how build a automatic dimmer cuircuit on top of those.

I already have moon lighting on a separate timer so that will remain as is.
