“The 6 puck lights are spaced 12" apart under a six foot long wall cabinet. They light up the base cabinet countertops below them. They are powered through to a dimmer light wall switch. The first light is plugged into an outlet we managed to place at the end of the inside of same wall cabinet. They together give sufficient light for tasks yet dimmable for a nice affect. The wires are effectively attached with 3M double sided tape so the wires aren't hanging down between pucks.”
