Choosing the Right 110V LED Strip Lights for Under Cabinets

When selecting LED strip lights designed for 110V use under cabinets, it is essential to consider factors such as power requirements, brightness, and safety certifications. Unlike low-voltage LED strips, 110V LED strips connect directly to your household power supply, so they must be UL-listed or have equivalent certifications to ensure safe operation.

Key considerations include:

  • Voltage Compatibility: Confirm the strip is rated for 110V AC input to avoid damage or fire hazards.
  • Wattage and Length: Calculate the total wattage based on strip length to ensure your circuit can handle the load.
  • Dimmability: Decide if you need dimmable lights and verify compatibility with dimmer switches designed for LED loads.
  • Color Temperature and CRI: Choose the color temperature (measured in Kelvins) that suits your space, typically between 2700K (warm white) and 4000K (neutral white), with a high CRI (Color Rendering Index) for accurate color representation.
  • Water Resistance: For kitchen environments where moisture is present, consider strips with an IP rating of at least IP65.

Tools and Materials Needed for Installation

Having the correct tools and materials ready will streamline the installation process and ensure a professional finish. The following list covers essential items for installing 110V LED strip lights under cabinets:

  • LED strip lights rated for 110V AC
  • Power cords and connectors compatible with the LED strip
  • Wire strippers and cutters
  • Electrical tape or heat shrink tubing
  • Screwdrivers (Phillips and flathead)
  • Drill with bits for mounting hardware
  • Measuring tape or ruler
  • Cable clips or adhesive mounting brackets
  • Voltage tester or multimeter
  • Wire nuts or terminal blocks
  • Optional: Dimmer switch compatible with LED lighting

Step-by-Step Installation Process

Begin by turning off power at the circuit breaker to ensure safety during installation. Use a voltage tester to confirm that the wires you will work with are not live.

  • Measure and Plan Placement: Measure the length of the cabinets where the LED strips will be installed. Plan the route for wiring and the location of the power source.
  • Prepare the Surface: Clean the underside of cabinets thoroughly to allow adhesive backing on the LED strips to stick properly.
  • Cut and Connect LED Strips: If necessary, cut the LED strips at marked intervals. Connect the strips using appropriate connectors designed for 110V strips, ensuring secure electrical contacts.
  • Mount the LED Strips: Peel the adhesive backing and press the strips firmly onto the cabinet underside. Use additional mounting brackets or clips if needed to secure the strips.
  • Wiring to Power Supply: Connect the LED strip wiring to the 110V power source, either directly to a junction box or through a plug-in power supply. Use wire nuts or terminal blocks for secure connections, and insulate with electrical tape or heat shrink tubing.
  • Install Switch or Dimmer: If including a switch or dimmer, wire it according to the manufacturer’s instructions, ensuring compatibility with 110V LED lighting.
  • Test the Installation: Restore power and test the lights for proper operation. Check for flickering or dimming issues and make adjustments if necessary.

Safety Precautions and Code Compliance

Working with 110V electrical systems requires adherence to safety standards and local electrical codes. To ensure compliance and reduce risk:

  • Always turn off power at the breaker before starting work.
  • Use materials and components rated for 110V AC.
  • Follow National Electrical Code (NEC) guidelines for wiring and installation.
  • Avoid overloading circuits by calculating total wattage of LED strips.
  • Secure all wiring to prevent strain or exposure.
  • Consider hiring a licensed electrician if unsure about any aspect of the installation.
Safety Checklist Purpose
Power Off at Breaker Prevents electrical shock during installation
Use UL-Listed Components Ensures product safety and code compliance
Proper Wire Gauge Handles current without overheating

Selecting the Appropriate 110V LED Strip Lights and Components

When installing LED strip lights under cabinets using a 110V power source, it is crucial to select components specifically designed for direct connection to standard household voltage. This ensures safety, performance, and compliance with electrical codes.

  • 110V LED Strip Type: Choose LED strip lights rated for 110V AC operation. These strips incorporate built-in resistors and circuitry to handle the higher voltage without requiring a separate transformer or driver.
  • Waterproof Rating: For kitchen environments, opt for LED strips with at least an IP44 rating to resist moisture and grease.
  • Power Consumption and Length: Determine total wattage by multiplying the strip wattage per meter by the desired length. This helps in planning circuit load and selecting compatible components.
  • Switching Mechanism: Decide whether to use a wall switch, inline switch, or remote control dimmer compatible with 110V LED strips.
  • Connectors and Mounting: Use connectors rated for 110V and ensure mounting brackets or adhesive backing can support the strip securely under cabinets.
Component Specification Purpose
110V LED Strip Rated for 110V AC, IP44 or higher Direct lighting source under cabinets
Inline Switch or Dimmer Compatible with 110V AC LED strips Control on/off and brightness levels
Power Cord with Plug Standard 110V plug, grounded Connection to household power outlet
Mounting Clips or Adhesive Tape Heat-resistant and strong adhesion Secure placement under cabinets
Wire Connectors and Junction Boxes Rated for 110V wiring Safe electrical connections and junctions

Preparing the Installation Site and Ensuring Electrical Safety

Proper preparation of the installation area and adherence to electrical safety standards are vital when working with 110V AC lighting.

Begin by cleaning the underside of the cabinets thoroughly to remove dust, grease, and residues that can affect adhesive or mounting hardware. Measure the length and identify the exact placement to ensure even lighting distribution and conceal wiring paths.

Before starting any wiring work, turn off power at the circuit breaker to prevent electrical shock. Use a non-contact voltage tester to confirm the power is off.

  • Check Local Electrical Codes: Verify that the installation complies with local regulations, especially concerning wiring, grounding, and fixture mounting.
  • Grounding: Ensure the LED strip and all metal components are properly grounded to prevent electrical hazards.
  • Wire Routing: Plan wiring routes to avoid heat sources, water exposure, or moving parts. Use conduit or cable raceways if required.
  • Secure Wiring: Use cable clips or ties to prevent wires from sagging or being pinched.
  • Load Capacity: Confirm the circuit can safely handle the additional load from the LED strip lights.

Step-by-Step Installation Process for 110V LED Strip Lights Under Cabinets

  1. Measure and Cut the LED Strip: If the LED strip is cuttable, cut only at marked intervals. Use sharp scissors or a cutting tool to ensure clean edges.
  2. Attach Mounting Hardware: Install mounting clips or peel the adhesive backing on the strip and press firmly to secure it under the cabinet. Ensure the strip is straight and aligned.
  3. Wire the Strip to Power: Connect the LED strip’s input wires to the power cord. Typically, the brown or black wire is live (hot), blue or white is neutral, and green/yellow is ground. Use wire nuts or connectors rated for 110V wiring.
  4. Install the Switch or Dimmer: If using an inline switch or dimmer, connect it in series with the live wire. Mount the switch in an accessible location.
  5. Test the Connection: Before finalizing, restore power and test the strip light operation. Check for flickering, uneven lighting, or unusual heat.
  6. Secure and Conceal Wiring: Use cable management solutions such as clips, raceways, or conduits to neatly route wires along cabinet edges or walls.
  7. Finalize Installation: Ensure all components are firmly mounted, and no wires are exposed. Restore power fully and operate the system.
