Begin by researching which LED light fixtures are appropriate for your kitchen application, where you will install them, and which electrical outlet will power them. The fixtures chosen for our project require a transformer that steps down 120 volt house current to 12 volts. From the transformer, the light fixtures can be arrayed in a series with each successive light module plugging into the next light with a small pigtail provided by the light manufacturer. All lights energized by the single transformer will be controlled with a dimmer switch, so we decide to rewire an unused telephone jack site for the dimmer switch and hide the transformer inside the cabinet. Before you start, read the manufacturer's instructions for installation and wiring.
