Integrated Lighting Systems:
All dimming modules are inside an enclosure in an electrical room. Requires wiring from loads to go to central dimming modules unlike traditional switch. In a New Home before electrical work begins this type of integrated lighting system is designed.
Stand-Alone Lighting Controls:
It sounds like stand-alone but these are also integrated. Stand-alone means, each traditional switch to be replaced with a smart dimming switch. These smart dimmers are integrated wirelessly and via programming. In any existing infrastructure these type of dimmers can be installed.
