If you have been searching for a reliable, cost-effective way to brighten up your kitchen countertops and workspace, Costco under cabinet lighting might be exactly what you need. Whether you are remodeling a home kitchen, upgrading a DIY workspace, or simply looking for a smarter lighting solution that eliminates shadows while you prep food, Costco offers a curated selection of under-cabinet LED kits and fixtures that balance quality with value. This guide dives deep into everything you need to know about choosing, installing, and getting the most out of under-cabinet lighting from Costco, covering product options, installation best practices, and expert-backed recommendations that go beyond the basics.
Why Under Cabinet Lighting Matters in the Kitchen
Under cabinet lighting is more than a decorative upgrade. It is a functional necessity that transforms how you use your kitchen workspace. Overhead ceiling lights cast shadows directly onto countertops, making it difficult to chop vegetables, read recipes, or spot spills. Task lighting mounted beneath wall cabinets eliminates these blind spots and creates an even, bright surface across your prep area. Research in kitchen design consistently ranks proper task lighting as one of the top three features that impact daily kitchen satisfaction, right alongside counter space and appliance layout.
Key benefits of adding LED under-cabinet lights include:
- Improved visibility on countertops for food preparation and cooking tasks
- A modern, layered lighting design that elevates the overall kitchen ambiance
- Energy efficiency, since LED strips and fixtures use a fraction of the electricity compared to traditional incandescent bulbs
- Long lifespan, with quality LED kits lasting 30,000 to 50,000 hours or more
- Slim, discreet profiles that tuck neatly beneath cabinets without protruding into the kitchen
Costco’s selection of under-cabinet lighting options gives members access to well-known brands and curated kits without the markup you might find at specialty retailers, making it a smart starting point for both beginners and experienced DIYers.
Types of Under Cabinet Lighting Available at Costco
Costco carries several categories of under-cabinet lighting solutions, each suited to different kitchen layouts, budgets, and skill levels. Understanding these categories helps you narrow down the right product before you browse the aisle or visit the warehouse.
LED Strip Light Kits
LED strip kits are the most popular under-cabinet option at Costco, and for good reason. These adhesive-backed light strips come in flexible or rigid formats and are designed to mount directly beneath cabinets with minimal tools. Most kits available through Costco include everything you need: the LED strip, an AC adapter or hardwired driver, connectors, and mounting clips. Popular brands in this category often feature tunable white lighting, which allows you to adjust the color temperature from warm white to cool daylight, giving you flexibility for different tasks and moods.
Puck Lights
Under-cabinet puck lights are small, circular fixtures that provide focused pools of light. They are an excellent choice if you prefer a more traditional fixture look over the sleek, continuous line of a strip light. Costco offers both hardwired and plug-in puck light options, with some kits including multiple pucks and a central transformer. Puck lights work especially well over bar areas, peninsulas, or narrow countertops where you need concentrated illumination in specific zones.
Hardwired Under Cabinet Light Bars
For a more permanent and polished installation, Costco carries light bar systems that integrate directly into your kitchen’s electrical wiring. These fixtures typically mount flush to the underside of the cabinet and deliver a clean, uninterrupted line of light. Hardwired options require a bit more electrical knowledge, but the result is a seamless, professional-grade look with no visible power adapters or cords.
Smart Under Cabinet Lighting
Some Costco under-cabinet lighting kits now include smart features compatible with Wi-Fi or voice assistants like Amazon Alexa and Google Home. These systems let you dim the lights, change color temperatures, and set schedules or scenes using a smartphone app. If you are building a connected smart home, this category adds convenience and energy control that traditional kits cannot match.
Top Costco Under Cabinet Lighting Brands and Kits
Costco partners with several reputable lighting brands to stock its under-cabinet product line. Some of the names you will frequently encounter include WAC Lighting, Hampton Bay, EcoSmart, and Barrage Lighting. Each brand brings a slightly different approach to design, brightness, and installation method.
WAC Lighting is a standout for members looking for a premium under-cabinet experience without paying premium retail prices. Their kits at Costco often feature high color rendering index (CRI) ratings above 90, which means colors appear more natural and true to life under the light, a critical factor for kitchen tasks like food preparation and presentation. Hampton Bay kits tend to be more budget-friendly and accessible, making them a great entry point for first-time installers. EcoSmart focuses on energy-efficient LED solutions with solid build quality at a competitive price point.

How to Choose the Right Under Cabinet Lighting for Your Kitchen
Selecting the best under-cabinet lighting for your space depends on several practical factors that go beyond just picking the most popular option on the shelf. Consider the following when evaluating Costco’s offerings.
- Measure your cabinet length. Measure the full length of the underside of your cabinets where you plan to install the lights. This determines how many strip meters, pucks, or light bars you need. Always buy slightly more length or fixtures than you think you need to avoid gaps in coverage.
- Consider your color temperature preference. Warm white (2700K – 3000K) creates a cozy, inviting feel and works well in traditional kitchen designs. Cool daylight (4000K – 5000K) provides crisp, alerting light ideal for modern kitchens and serious cooking tasks. Tunable white kits give you the best of both worlds.
- Check the CRI rating. A color rendering index of 90 or above ensures that food colors, ingredients, and textures look natural and accurate under the light. This is especially important if you cook frequently and want to judge the visual quality of your food easily.
- Decide between plug-in and hardwired. Plug-in kits are the simplest to install and are perfect for renters or anyone who wants a no-wiring solution. Hardwired kits require an electrician or basic electrical wiring knowledge but deliver a cleaner, more permanent installation with no visible power cords.
- Think about dimming capability. Many Costco under-cabinet kits are compatible with dimmer switches, which lets you adjust brightness for different times of day or activities. If you plan to use dimming, make sure the kit includes a compatible dimmer or purchase one separately.
Installation Tips for Costco Under Cabinet Lighting
Installing under-cabinet lighting does not require professional electrician skills for most plug-in and adhesive strip kits, but doing it correctly makes a significant difference in the final result. Follow these expert tips to get a clean, professional-looking installation.
- Clean the cabinet underside thoroughly with rubbing alcohol before applying adhesive strips. Any grease or dust will prevent the adhesive from bonding properly.
- Install the light strip or fixture as close to the front edge of the cabinet as possible. This position casts light forward onto the countertop and minimizes shadows cast by the cabinet itself.
- Use a continuous run of one strip per cabinet rather than splicing multiple shorter strips together. Splicing creates potential points of failure and visible connectors that detract from the clean look.
- For hardwired installations, always turn off the circuit breaker at the panel before starting any electrical work. Use a voltage tester to confirm the power is off before touching any wires.
- Consider installing a dimmer switch on the circuit to control brightness. A simple in-line dimmer module costs very little and dramatically improves the versatility of your under-cabinet lighting setup.
- If your cabinets have a toe-kick or an angled underside, measure carefully and use flexible strip lights rather than rigid bars, which will not conform to curved or angled surfaces.
Common Mistakes to Avoid with Under Cabinet Lighting
Even with a great product from Costco, certain installation and selection mistakes can undermine the quality of your under-cabinet lighting setup. Avoid these common pitfalls:
- Choosing a light strip that is too short for the full length of the cabinet, leaving dark spots at the edges of the countertop
- Ignoring the transformer wattage rating and overloading it by connecting too many fixtures or strips to a single driver
- Placing the light source too far back under the cabinet, which casts a shadow directly on the countertop where you work
- Selecting a low CRI LED strip that makes food look dull or discolored under the light
- Forgetting to account for the power cord path when planning the installation location, leading to visible cords or difficult routing
Costco Under Cabinet Lighting FAQs
What is the best under cabinet lighting kit at Costco?
The best under-cabinet lighting kit at Costco depends on your kitchen layout and budget. For most members, WAC Lighting LED strip kits and Hampton Bay plug-in puck light sets are the top-rated options. WAC Lighting offers superior color rendering and tunable white features, while Hampton Bay provides excellent value with easy plug-and-play installation. Check your local Costco’s online inventory for current bestsellers, as product availability rotates seasonally.
Can I install Costco under cabinet lighting myself?
Yes, the vast majority of under-cabinet lighting kits sold at Costco are designed for DIY installation. LED strip kits with adhesive backing and plug-in power adapters require no wiring at all. Hardwired kits and light bar systems require basic electrical knowledge, and if you are uncomfortable working with household wiring, it is best to hire a licensed electrician for those installations.
How bright should under cabinet lighting be for a kitchen?
For kitchen task lighting, aim for approximately 500 lumens per linear foot of countertop, which is the recommended standard from kitchen lighting designers. Most quality Costco under-cabinet LED strips deliver between 200 and 400 lumens per foot, so you may need to use a higher-output product or double up strips for brighter work surfaces like knife prep areas and stovetops.
Do Costco under cabinet lights come with dimmers?
Some Costco under-cabinet lighting kits include a built-in dimmer or are compatible with aftermarket in-line dimmers. However, not all kits support dimming. Before purchasing, check the product description carefully for dimmable compatibility. If dimming is important to you, look for kits explicitly labeled as dimmable and consider purchasing a separate compatible dimmer switch for the cleanest control option.
What is the lifespan of Costco under cabinet LED lighting?
Quality LED under-cabinet lighting kits available at Costco typically last between 30,000 and 50,000 hours, which translates to roughly 10 to 15 years of average daily kitchen use. This lifespan far exceeds traditional incandescent under-cabinet bulbs and means you will rarely need to replace the lights once installed. The LED driver or adapter may need replacement after several years, but the strip or fixture itself should last the lifetime of your kitchen.
Is Costco under cabinet lighting waterproof or moisture-resistant?
Most under-cabinet lighting kits at Costco are not fully waterproof, but they are designed to handle typical kitchen conditions, including exposure to steam and minor splashes. If you plan to install lighting in a damp area such as near a sink or in an outdoor kitchen, look for kits with an IP65 or higher ingress protection rating. Standard indoor kits without this rating should be kept away from direct water exposure.
Final Thoughts
Costco under cabinet lighting offers an outstanding combination of quality, value, and selection that makes it one of the best places to source your kitchen task lighting. Whether you are a complete beginner looking for a simple plug-in LED strip kit or an experienced DIYer planning a hardwired light bar installation, Costco has options that deliver real performance without the premium price tag of specialty lighting stores.
