DIY: How To Install Lights Under Kitchen Cabinets

Can you install lights under kitchen cabinets yourself? Yes, you absolutely can! Installing lights under kitchen cabinets yourself is a rewarding DIY project that can dramatically improve both the functionality and aesthetic of your kitchen. What are the benefits of under cabinet lighting? It provides task lighting for your countertops, reduces shadows, and creates a warm, inviting ambiance.

This comprehensive guide will walk you through everything you need to know to successfully install lights under your kitchen cabinets. We’ll cover choosing the right type of lighting, planning your layout, and the actual installation process, including how to handle cabinet lighting wire hiding for a clean finish.

Choosing Your Under Cabinet Lighting

The first step in your kitchen cabinet lights DIY journey is selecting the best under cabinet lighting for your needs and style. There are several popular options available, each with its own advantages.

LED Under Cabinet Lights

LED under cabinet lights are by far the most popular choice today, and for good reason.

  • Energy Efficiency: LEDs use significantly less energy than traditional incandescent or halogen bulbs, saving you money on your electricity bills.
  • Long Lifespan: They last much longer, meaning you won’t have to replace them as often.
  • Low Heat Output: LEDs produce very little heat, making them safe to install close to cabinets and preventing them from drying out or damaging wood over time.
  • Versatility: They come in a wide range of styles, colors (including warm white, cool white, and color-changing options), and form factors (strips, pucks, bars).
  • Dimmable Options: Many LED systems are dimmable, allowing you to control the brightness and mood of your kitchen.
Types of LED Under Cabinet Lights

Within the LED category, you’ll find a few main types of fixtures:

  • LED Strips (Tape Lights): These are flexible, adhesive-backed strips of LEDs that can be cut to size. They are excellent for providing continuous, even light along the length of your cabinets. They are particularly good for achieving subtle under cabinet lighting ideas.
  • LED Puck Lights: These are small, circular fixtures that are often sold in kits. They are easy to install and provide focused pools of light, which can be useful for highlighting specific areas or objects.
  • LED Bars/Rods: These are rigid fixtures that offer a more directed beam of light. They are ideal for tasks requiring brighter illumination directly below.
Other Lighting Options (Less Common for DIYers Today)

While LEDs dominate, you might encounter these older technologies:

  • Xenon: Brighter than halogens and more energy-efficient than incandescents, but still less efficient than LEDs. They also produce more heat.
  • Halogen: Produce a bright, warm light but are very inefficient and generate significant heat, making them less ideal for under-cabinet installations.
  • Fluorescent: Offer good efficiency but can produce a less flattering light and may have a slight hum. They are also bulkier.

For most DIY projects, LED under cabinet lights are the clear winner.

Powering Your Lights: Hardwiring vs. Battery Operated vs. Wireless

How will your under cabinet lighting installation be powered? This is a crucial decision that impacts the complexity of the project.

Hardwiring Under Cabinet Lights

Planning Your Under Cabinet Lighting Installation

Before you start screwing, drilling, or sticking anything, good planning is essential for a successful under cabinet lighting installation.

1. Assess Your Needs and Desired Effect
  • Task Lighting: Do you need bright light for chopping vegetables and food preparation? LED bars or strips with a higher lumen output are good choices.
  • Ambient Lighting: Are you looking for a softer glow to enhance the mood? Warmer color temperatures and dimmable strips work well.
  • Accent Lighting: Do you want to highlight specific features, like decorative items or backsplash patterns? Puck lights can be effective here.
2. Sketch Your Layout

Take a piece of paper and sketch your kitchen cabinets. Mark where you want the lights to be placed. Consider:

  • Coverage: Do you want light to cover the entire length of the counter, or just specific work areas?
  • Spacing: For LED strips, you’ll want continuous coverage. For puck lights, plan the spacing to avoid dark spots.
  • Power Source: Identify the nearest electrical outlet or junction box if you plan to hardwire or use plug-in options.
  • Switch Location: Where do you want to control your lights? An existing switch? A new switch? A remote control?
3. Measure and Calculate
  • Measure the length of the cabinet runs where you plan to install lighting.
  • If using LED strips, note that they are often sold in specific lengths (e.g., 5 meters) and can be cut to size at designated cut marks. Ensure you have enough length.
  • Determine the number of puck lights needed based on your spacing plan.
4. Choose Your Cabinet Lighting Kit or Components

You can often buy complete cabinet lighting kits that include everything you need: lights, power supply, connectors, and sometimes even a remote or switch. Alternatively, you can buy components separately if you have specific needs.

  • Color Temperature:
    • Warm White (2700K-3000K): Similar to traditional incandescent bulbs, creates a cozy, inviting atmosphere. Great for general ambiance.
    • Cool White (3500K-4500K): Brighter and more neutral, good for task lighting and kitchens where a crisp, clean look is desired.
    • Daylight (5000K-6500K): Very bright and cool, mimics natural daylight. Excellent for intense task lighting.
  • Brightness (Lumens): Higher lumens mean brighter light. Check the product specifications.
  • Color Rendering Index (CRI): A CRI of 90+ is ideal for kitchens as it accurately shows the true colors of food and decor.
