There were many zones in the kitchen, probably more than one would need in a real house. I missed which lights were specifically separate, but in theory you could have the under-counter lights as one zone, the in-cabinet lights as another, the ceiling lights as yet another, and the hanging lights as one more.
Pop into the kitchen for a late night snack, maybe you just want the under-counter lights full on, but the ceiling lights at 20%. Then all on for a prep and cook for a party, but the hanging lights at 60% and in-cabinet at 30% to set a mood. Each of these "Scenes" can be programmed to a wireless remote control or to a control on a wall plate.
Dimmers could also keep energy costs down for this well-lit room.
