Hardwired Under Cabinet Lighting

The basic process for installing hardwired under cabinet lighting involves a few key steps. First, plan your layout and run your low-voltage wiring from the power supply location to where each light will be. This wire is often hidden inside walls or cabinets. Next, mount your LED strips inside their aluminum channels and fix the channels under the cabinets. Finally, connect all your lighting runs back to the low-voltage side of the LED driver, and have a qualified electrician connect the driver's high-voltage side to your home's 120V AC circuit.

For the best under cabinet lighting for kitchen counters where you're actually working, you want bright, even, high-quality light. That almost always means an LED strip light with a high CRI (95+) inside a diffused aluminum channel. This combination eliminates the 'dots' and shadows you can get from puck lights, giving you a smooth, continuous line of light that shows true food colors. Look for something around 4000K for a clean, neutral white.

I strongly recommend it, yes. An aluminum channel does two critical jobs for an under cabinet lighting installation. First, it acts as a heat sink, pulling heat away from the LEDs and extending their lifespan significantly. Second, the diffuser cover provides a clean, finished look and smooths out the light, getting rid of hot spots and glare. Sticking a bare strip directly to a wood cabinet is a common mistake that can lead to early failure.

The best hardwired under cabinet lighting isn't a single product, it's a well-matched system. It starts with a high-CRI (95+) LED strip for accurate color rendering. That strip is powered by a reliable, UL-listed driver from a brand like MeanWell. It's housed in a proper aluminum channel for heat dissipation and diffusion. Finally, it's all controlled by a dimmer and controller that are fully compatible. Getting those four components right is the secret.

For a professional look, the wiring for under cabinet lights needs to be planned before the cabinets go in, if possible. Typically, an electrician runs a 120V line to a junction box, often above the cabinets or in a pantry. The LED driver is placed there. From the driver, you run low-voltage two-conductor wire down to the lights, either behind the drywall or tucked into the back corner of the cabinets. Using channels with wire management also helps keep things tidy.

It depends on the look you want. Puck lights create pools of light, which can be great for highlighting specific objects or creating a more traditional, scalloped effect. For task lighting over a countertop, however, the best under kitchen cabinet lighting is almost always a continuous LED strip in a channel. It provides a seamless, even wash of light with no shadows or dark spots, which is much better for food prep.

Absolutely, this is a huge part of what we do. Many of the systems we ship are built to a customer's drawing and never appear on the website. Just send our engineering team a sketch of your cabinets with dimensions—even a photo of a drawing on a napkin works. We'll spec out the exact lengths of strips, channels, the right driver, and all the connectors you need, and send back a parts list and quote, usually within 12 hours. There's no fee for this service and no obligation to order.
