Black & Decker 1-Bar Led Under Cabinet Lighting Accessory Light, Cool White, 9"

Why I added the 9-inch accessory bar

Adding light under a cabinet is one of those upgrades that immediately makes a kitchen feel more functional. I already had a cool-white Black & Decker under-cabinet kit in place, but I still had a dark patch over a prep zone and a coffee station. Rather than start over, I added the 9-inch accessory bar. It’s a simple, linkable expansion piece designed to snap into the existing ecosystem, and it did exactly what I needed: fill the gaps, match the color, and tie into the same motion and dimming controls.

Installation and setup

The appeal here is how little fuss it takes to get from box to light. The bar includes a low-profile mounting clip, a wire clip, two screws, a jumper extender, and three jumper cables (4, 12, and 30 inches). In my case, I mounted the bar under the cabinet lip with the included clip and connected it to my existing run with the 12-inch jumper. From opening the box to flipping the switch took minutes.

Black & Decker calls this tool-free, and that matched my experience. The clip design lets you snap the bar into place without drilling. Screws are included if you want a permanent install or you’re working with a textured surface, but I was able to seat the clip securely and manage the cable with the wire clip and some low-profile adhesive raceway I already had on hand. The variety of jumper lengths matters more than you might think: being able to bridge a longer span with the 30-inch jumper without daisy-chaining multiple short ones keeps the layout clean and reliable.

A few setup tips that made a difference:
- Dry-fit everything first. Temporarily position the bar and sensor/controller, then choose your jumper lengths before committing to any clips.
- Route cables toward the back of the cabinet where the shadow line hides them. If your cabinet bottoms are glossy or very smooth, clean with isopropyl alcohol before sticking any cable management accessories.
- If you’re mixing bar lengths, place the shortest bars in areas where you need focused task light rather than broad wash.

Light quality and output

Cool white is the right choice for prep work. This bar matches the rest of my kit with a neutral-leaning-cool tone that makes edges and printed measurements easier to see without skewing colors unnaturally. The lens diffuses the LEDs well, so you get a continuous line of light with minimal dotting on reflective countertops. On a darker backsplash, the cutoff is crisp and doesn’t flare.

Brightness is adjustable in ten steps, which is more useful than it sounds. I keep the run over the main prep area near the top end and dial the coffee station down several clicks so it doubles as an evening nightlight. The stepping is even, not jumpy, and I didn’t notice flicker at any level. Heat is a non-issue; after long sessions at higher brightness, the bar stayed just warm to the touch.

Controls: motion and timer

The biggest quality-of-life improvement in this ecosystem is the hands-free control. The accessory bar listens to the same motion sensor module and power button as the rest of the linked run, so it turns on and off in sync. If your hands are wet or dusty, being able to wave to bring up light is a genuine convenience. The sensor triggered reliably in day-to-day use and didn’t false-trigger from across the room; placement matters, so aim the sensor toward the working area rather than a walkway.

There’s also an optional three-hour auto-off timer. I tend to leave the under-cabinet lights on in the evening for ambient light, and the timer keeps me from discovering them still glowing in the morning. It’s a small feature that saves energy without adding another thing to remember at the end of the day.

Linkability and compatibility

This bar is intended as an add-on, not a standalone light. It needs to connect to a compatible cool-white Black & Decker under-cabinet kit (models such as LEDUC9-5CK, LEDUC9-3CK, LEDUC9-1CK, LEDUC18-1CK, LEDUC24-1CK). Within that ecosystem, linking is truly plug-and-play: line up the connectors, click in, and the new bar becomes part of the chain, sharing both power and control.

Two practical notes:
- Power budget still matters. If you’re pushing the limits of your existing power supply with multiple bars, check the original kit’s power rating to ensure you’re not overloading it before adding more.
- Keep color temperature consistent. This accessory is cool white; mixing it with warm-white bars will look mismatched on a continuous run.

Build quality and longevity

The bar feels solid for its size, with a rigid body and a diffuser that sits flush. There’s no rattle, no flex that suggests a fragile housing, and the connectors seat with a positive click. The LEDs are rated for up to 50,000 hours, and the whole system draws a fraction of the energy of incandescent puck lights. More important in everyday use, there’s no audible humming, and the light comes on instantly without any lag.

Because it’s a low-profile bar, it hides well in the cabinet shadow line. If you work over highly reflective stone, the even diffusion is appreciated; you get illumination without the distracting “pearl necklace” of LED hotspots.

Everyday use

After a few weeks, the 9-inch accessory bar just disappears into the workflow—in a good way. It doesn’t call attention to itself; it simply expands your coverage. Over a cutting board, it removes an annoying shadow from an upper cabinet. In a corner, it turns a decorative shelf into a usable workspace. And because it’s tied into the same control scheme as the rest of the run, you don’t have to think about it as a separate light.

The ten-step dimming also makes it versatile beyond task lighting. At lower levels, it becomes accent lighting for evenings or early mornings, and the cool-white tone still reads clean rather than blue at those settings.

Limitations and quirks

• Not standalone: This is an accessory bar that requires a compatible cool-white kit. If you’re starting from scratch, buy a full kit first.
• Corded means cable management: Expect to spend a few extra minutes hiding jumpers for a tidy look. The provided wire clip helps, but a pack of stick-on cable clips or a slim raceway goes a long way.
• Motion sensor placement matters: Mount the sensor where your hand naturally passes during tasks, not near a high-traffic edge where passersby might trigger it.
• Color preference: Cool white is great for clarity, but if you prefer a warm, cozy under-cabinet glow, this isn’t the right match.

None of these are deal-breakers, but they’re worth planning for so you get a clean, integrated result.

Tips for the cleanest install

• Map the run and choose jumper lengths before mounting anything.
• Test the motion sensor location with temporary tape until the trigger zone feels natural.
• Clean mounting surfaces thoroughly to help clips adhere and stay put.
• Use the included screws if your cabinet undersides are textured or unfinished and you want extra security.

The bottom line

As an expansion piece, the 9-inch accessory bar checks all the boxes: quick to install, genuinely low-profile, bright with fine-grained control, and fully integrated with motion sensing and the optional three-hour timer. The included jumper lengths make layout flexible, the light quality is crisp and even, and the energy savings over legacy puck lights is obvious in both heat and usage.

Recommendation: I recommend this accessory bar to anyone looking to extend a Black & Decker cool-white under-cabinet kit. It’s an easy, effective way to fill dark spots or balance a run without introducing a new control scheme or mismatched color. Skip it only if you’re after a warm-white look, need a battery-powered solution, or don’t already own a compatible kit—in those cases, start with the right full kit or a different color temperature. For everyone else, this is a straightforward, reliable upgrade that does exactly what it promises.
