When building a new home or remodeling an older home, centralized lighting enables you to remove the wall clutter created by multiple light switches located in one place to control many lights. In the kitchen, you may have three zones of ceiling cans, a chandelier, pendant lights over the island and under-cabinet lights. That's a clumsy 7-gang switch layour that occupies a great deal of wall space and is not the sleekest in appearance. By having all switching taking place in a centralized panel (sort of like your fuse panel in the garage), you can be left with one, multi-button switch (with each button engraved with its function) on the kitchen wall. The same occurs in your bathroom, stair landings between floors, bedrooms with accent lights, night stand lights, ceiling lights and fans. Magic -- clutter gone.
