Under cabinet lighting is a transformative upgrade that brings both style and function to your kitchen or workspace. It brightens countertops, highlights backsplashes, and creates a warm ambiance. This guide is designed to help you install under cabinet lighting yourself, with clear, actionable steps and expert tips. Whether you prefer sleek LED strips or classic puck lights, you’ll find practical advice on materials, tools, and installation techniques that fit your skill level and budget. Ready to illuminate your space beautifully and efficiently? Let’s get started.
Under cabinet lighting can be installed using various types of fixtures, including LED strips, puck lights, or fluorescent tubes. LED strips are popular for their slim profile and energy efficiency, while puck lights offer focused illumination for specific areas. Before installation, it’s essential to plan the layout, measure your cabinets precisely, and decide on a power source. Most installations require running low-voltage wiring to a transformer or connecting directly to your home's electrical system. This guide covers each phase, from selecting materials and tools to mounting and wiring your lights safely and effectively.
⚠️ Safety First
Always turn off power at the breaker before handling electrical wiring.
Use a voltage tester to confirm circuits are de-energized.
Follow manufacturer instructions and local electrical codes strictly.
If unsure about electrical work, hire a licensed electrician.
Wear safety glasses when drilling or cutting materials.

Step-by-Step Instructions
Step 1Plan and Measure Your Space⏱ ~30 min
Measure the length of your cabinets where you want the lighting installed. Decide on the type of lighting (LED strips or puck lights) and how many fixtures you need to cover the area evenly. Mark the layout under the cabinets using a pencil and a level to ensure straight lines.
💡 Pro Tip: Measure twice to avoid cutting LED strips incorrectly. Consider spacing puck lights about 12 inches apart for balanced illumination.

Step 2Choose and Prepare Your Lighting Fixtures⏱ ~45 min
Purchase LED strips or puck lights that fit your measurements and desired brightness (measured in lumens). If using LED strips, cut them at designated intervals using scissors or a utility knife. Test the lights by connecting briefly to the power supply before permanent installation.
💡 Pro Tip: Select warm white lights (2700K–3000K) for a cozy kitchen ambiance or cool white (4000K–5000K) for a modern, bright look.
Step 3Mount the Lighting Fixtures⏱ ~45 min
Attach mounting clips or peel and stick the LED strips under the cabinet along your marked lines. For puck lights, drill small pilot holes and secure them with screws provided. Ensure fixtures are flush with the cabinet bottom and evenly spaced.

💡 Pro Tip: Clean the mounting surface with rubbing alcohol before applying adhesive tape for better adhesion.
Step 4Run Electrical Wiring⏱ ~60 min
Turn off power at the breaker. Run low-voltage wires from the lights to the power supply, securing cables with cable management clips. Strip wire ends and connect them using wire connectors or nuts. Follow manufacturer wiring diagrams carefully.
💡 Pro Tip: Use a voltage tester to confirm power is off before touching wires. Keep wires neat to avoid clutter or damage.
Step 5Install the Power Supply and Switch⏱ ~45 min
Mount the transformer or power supply in an accessible but hidden location inside the cabinet or nearby wall. Connect the power supply to your home’s electrical circuit or plug it into an outlet. Install a switch or dimmer for easy control of your under cabinet lighting.
💡 Pro Tip: If unsure about wiring to home electrical systems, consult a licensed electrician to comply with local codes.
Step 6Test and Adjust Your Lighting⏱ ~30 min
Restore power and test your lighting setup. Adjust the position of lights if necessary for optimal coverage. Use the dimmer or switch to verify smooth operation. Tidy up any loose wires and secure all fixtures firmly.
💡 Pro Tip: Consider adding a diffuser or frosted covers for puck lights to soften harsh shadows.
💡 Pro Tips & Expert Advice
Use LED strips with built-in dimmers for customizable ambiance.
Label wires during installation to simplify future maintenance.
Consider wireless or smart lighting options for remote control via smartphone.
Test all components before final mounting to avoid rework.
