If you’re planning to install under cabinet lighting, you’ve probably asked yourself this question: should the lights go toward the front of the cabinet or toward the back?
It seems like a small detail, but it makes a huge difference in how your kitchen looks and functions.
The short answer: Place them toward the front. Here’s why — and what the experts say.
The Quick Answer
Install under cabinet lights toward the front of your upper cabinets, just behind the light rail (the decorative trim along the front edge).
This position directs light onto the center of your countertop — exactly where you need it for food prep, cooking, and reading recipes.
What Happens If You Install Them in the Back?
Many electricians prefer installing lights toward the back because it’s easier and saves them about 15 minutes of work. But this shortcut has real downsides:
| Installation Position | Result |
|---|---|
| Front (recommended) | Light falls on the center of the counter where you work |
| Back (not recommended) | Light mostly hits the backsplash, leaving the counter dim |
As one lighting expert put it: “If the light is stationed closer to the back wall, it primarily highlights the backsplash tile and not the counter, defeating the purpose of the light.”
5 Reasons to Install Under Cabinet Lights Toward the Front
1. Task Lighting, Not Backsplash Lighting
Under cabinet lighting is task lighting — its job is to illuminate your work surface. Upper cabinets are typically about 12 inches deep, while base cabinets are 24 inches deep. When you mount lights toward the front of the upper cabinets, the light lands in the middle of your counter where you actually work.
2. Better Visibility for Food Prep
Front-mounted lights reduce shadows caused by your body leaning over the counter. Rear-mounted lights cast light behind your work area, leaving your cutting board or cookbook in shadow.
3. Lights Stay Hidden
The front edge of your cabinets usually has a light rail — a decorative strip designed specifically to hide under cabinet lights. When you install lights toward the front, they sit behind this rail and cannot be seen from a seated position in the kitchen or nearby dining area.
If you install them toward the back, the lights become visible when you’re seated — which can be glaring and unattractive.
4. Less Glare
Front placement provides a softer, more even glow across your countertops and backsplash. Rear placement can create harsh glare off glossy backsplash tiles.
5. Professional Installers Agree
Experienced professionals consistently recommend front placement. On Houzz, one user shared: “I have had undercabinet lighting installed in 3 different kitchens. Always toward the front.”
What About Battery-Operated or Puck Lights?
The same rule applies: place them toward the front.
For puck lights, mount them at the front of the cabinet, spaced evenly. A good rule of thumb is to place them 20 to 24 inches apart for ideal beam spread, centered under the cabinet and aligned toward the counter.
For LED strip lights, install them parallel to the front edge, about 1-2 inches behind the light rail. Face the lights straight down, not angled toward the wall. Angling them toward the backsplash creates uneven lighting and wasted illumination.
When Would You Ever Mount Lights in the Back?
Some homeowners choose rear placement for ambient or dramatic effect — to highlight a beautiful textured backsplash or create a softer glow. However, most lighting professionals advise against this because it sacrifices the primary function: task lighting.
If you want both task lighting and backsplash accent lighting, you can install two separate rows — one toward the front for work light, and one toward the back for accent light (on a separate dimmer). This is a more expensive but more flexible option.
Installation Tips
Before permanently mounting your lights:
- Hold the lights in place and test both positions before drilling
- Plug them in and see where the light actually falls on your counter
- Check from a seated position to ensure the lights won’t be visible
- Consider adding a light rail or valance if your cabinets don’t have one — a simple 1-2 inch wood strip can hide the fixture and reduce glare
Summary
| Mounting Position | Effect on Counter | Visible from Seated Position? | Glare Level |
|---|---|---|---|
| Front (Recommended) | Well-lit, center of counter | No | Low |
| Back | Dim, mostly backsplash | Yes | Higher |
Bottom line: For the best task lighting, install your under cabinet lights toward the front of your cabinets. Don’t let an electrician convince you otherwise just because it’s easier for them — it’s your kitchen, and you’ll be using it for years.
