1. **Plan and Measure**: Determine the type of lighting (LED strips, puck lights, etc.) and measure the cabinet length to calculate the number of lights needed.
2. **Gather Materials**: Purchase the lighting kit, power supply, connectors, mounting hardware, and any necessary tools like a drill, screwdriver, and wire stripper.
3. **Turn Off Power**: Ensure the power to the area is turned off at the circuit breaker to avoid electrical hazards.
4. **Prepare the Surface**: Clean the underside of the cabinets to ensure proper adhesion of the lights.
5. **Layout the Lights**: Position the lights under the cabinets to ensure even distribution of light. Mark the spots for mounting.
6. **Install the Lights**:
- For LED strips, peel off the adhesive backing and stick them in place.
- For puck lights, use screws or adhesive pads to mount them.
7. **Connect the Wiring**:
- Connect the lights to the power supply using connectors or wire nuts.
- If hardwiring, run the wires through the cabinets and connect them to the existing electrical system.
8. **Install the Power Supply**: Mount the power supply in a discreet location, such as inside a cabinet, and plug it into an outlet or hardwire it.
9. **Test the Lights**: Turn the power back on and test the lights to ensure they work properly.
10. **Secure and Conceal Wires**: Use cable clips or raceways to secure and hide any visible wires for a clean look.
11. **Final Adjustments**: Make any necessary adjustments to the light positioning and ensure all components are securely fastened.
