Why Choose Under-Cabinet Lighting?

  • Stylish Ambiance: Add a warm, inviting glow to your kitchen décor.
  • Energy Efficiency: LED under-cabinet lights consume minimal power.
  • Increased Home Value: Modern lighting upgrades appeal to potential buyers.

Tools and Materials You’ll Need

  • LED under-cabinet light strips or puck lights
  • Low-voltage power supply or transformer
  • Wire nuts and electrical tape
  • Drill with driver bits
  • Wire strippers and pliers
  • Measuring tape and pencil
  • Voltage tester

Step-by-Step Wiring Guide

1. Plan Your Lighting Layout

Measure the length of your cabinets and decide where each light fixture will go. Sketch a simple diagram showing the positions and how wires will run back to your power source. This planning ensures a clean installation and helps you estimate the required materials.

2. Turn Off the Power and Prepare

Safety first! Switch off the circuit breaker that controls your kitchen outlets and lights. Use a voltage tester to confirm there’s no power at the wiring point. Gather your tools and materials before you begin.

3. Mount the Fixtures

Attach the LED light strips or puck lights under the cabinets using the included mounting clips or screws. Keep fixtures evenly spaced for balanced illumination. If you’re using a track system, secure the track first, then snap the lights into place.

4. Connect the Wiring

Run low-voltage wire from each lighting fixture back to the transformer location. Strip about ¾ inch of insulation from the wire ends. Connect the positive and negative leads of the light fixtures to the matching terminals on the transformer, using wire nuts for a secure fit. Wrap connections with electrical tape for extra protection.

5. Install the Transformer

Mount the transformer in a cool, dry location—often inside a cabinet or closet near an outlet. Plug it into a nearby receptacle or hardwire it to a dedicated circuit following local code requirements. Many homeowners choose to use a licensed electrician for this step to ensure compliance and safety.

6. Test and Finalize

Restore power at the breaker panel and switch on your new under-cabinet lights. Check each fixture to confirm it’s working properly. Tuck away any excess wires using cable clips or wire channels for a tidy finish.
