Having these tools ready minimizes interruptions and allows for a safer installation process.

Preparing for Installation

Proper preparation is essential to ensure the lighting fixtures are securely mounted and wired correctly. Start by turning off the power to the area where the lights will be installed, preferably at the circuit breaker, to prevent electrical shock.

Measure the length of the cabinets to determine the amount of lighting needed. Mark the desired locations for the lights, keeping in mind the optimal spacing and aiming to avoid shadows on the countertop. If installing multiple fixtures, plan the wiring route to minimize visible cables and maintain a neat appearance.

Inspect the cabinet underside to confirm that the mounting surface is clean and free from obstructions such as screws, nails, or uneven surfaces. In some cases, you may need to pre-drill holes for screws or anchors to secure the lighting fixtures.

Wiring and Power Connection

Connecting the under cabinet lighting to a power source requires careful attention to electrical codes and safety standards. There are typically three common wiring options:

  • Plug-in installation: The easiest method involves plugging the lighting into an existing outlet under the cabinet. This is suitable if outlets are conveniently located.
  • Hardwired installation: Involves connecting the lighting directly to the home’s electrical wiring. This method often requires a licensed electrician and provides a cleaner look without visible cords.
  • Battery-operated lighting: Requires no wiring but may be less reliable for continuous use and needs battery replacement or charging.

When hardwiring, use a voltage tester to verify that the power is off before handling wires. Connect the fixture’s wires to the corresponding house wires—typically black (live), white (neutral), and green or bare copper (ground). Secure connections using wire nuts or connectors and wrap with electrical tape for extra safety.

If using a transformer or power supply, ensure it matches the voltage requirements of the lighting fixtures. Follow the manufacturer’s instructions carefully for installation.

Mounting Under Cabinet Lights

The mounting method depends on the type of lighting selected. For LED strips, adhesive backing often facilitates easy placement, but additional mechanical fasteners such as clips or brackets may be necessary for long-term stability.

Puck lights typically require drilling holes for screws to attach the fixtures securely. Position them evenly along the cabinet underside for consistent illumination. When using fluorescent or halogen fixtures, follow the manufacturer’s mounting instructions, which may involve brackets or specialized hardware.

Key points for mounting:

  • Use a level to ensure the fixtures are straight.
  • Avoid mounting too close to the cabinet front edge to prevent glare.
  • Ensure fixtures do not interfere with cabinet doors or drawers.
  • Keep wiring concealed using cable clips or raceways to maintain a tidy appearance.

Testing and Adjusting the Lighting

After installation, restore power and test the lighting to confirm proper function. Turn the lights on and check for even illumination without flickering or dark spots. If dimmers or smart controls are installed, verify compatibility and operation.

Adjust positioning as needed to reduce shadows and glare. For LED strip lights, trimming excess strip length may be possible according to manufacturer guidelines, allowing for a perfect fit.

Document any issues encountered during testing to address them promptly, ensuring safe and effective lighting performance.
