What Size Under Cabinet Lighting Do I Need? | Lepotec Guide

If you’re planning to upgrade your kitchen, closet, or workspace, under cabinet lighting is one of the smartest and simplest ways to add both style and functionality. But when it comes to choosing the right size of under cabinet lights, things can get a little confusing. Should you go for long bars or short ones? Do you need one light per cabinet, or just a few to cover the whole space?

Don’t worry — this guide by Lepotec, a trusted brand specializing in LED rechargeable motion sensor lights, will walk you through everything you need to know to pick the perfect size for your space.

Why Size Matters in Under Cabinet Lighting

The size of your under cabinet lighting determines how evenly your light spreads across your countertop or workspace. If your lights are too short, you’ll end up with dark spots and uneven illumination. If they’re too long or too bright, you may get harsh reflections or wasted light.

Choosing the right size ensures:

• ✅ Even lighting across your countertop

• ✅ A clean and professional appearance

• ✅ Energy efficiency — using just the right amount of light

• ✅ A perfect match with your cabinet layout

At Lepotec, we design our LED lights to fit a variety of cabinet sizes, making it easy for homeowners to create seamless and stylish lighting setups.

Step 1: Measure Your Cabinets

Before you buy, take a measuring tape and note the width and depth of your cabinets.

For example:

• Standard kitchen wall cabinets are usually 12 inches deep.

• Base cabinets can vary between 24 to 36 inches wide, depending on design.

• If you’re lighting a closet or shelf, the depth might range from 10 to 15 inches.

These numbers will help you figure out how many lights you need and what length works best for each section.

Step 2: Choose the Right Light Length

Lepotec offers several lengths of rechargeable motion sensor lights, such as 7.8 inches, 12 inches, and 15 inches — giving you flexibility to fit different cabinet spaces.

Here’s a simple breakdown to help you decide:

If your cabinets are extra long, you can easily connect two or more Lepotec lights in a row. Their sleek aluminum design blends perfectly, giving the illusion of a continuous light bar.

Step 3: Think About Light Placement

Placement is just as important as size. Ideally, your under cabinet lights should be mounted toward the front edge of the cabinet (not in the center). This helps the light spread evenly across the countertop instead of shining directly down the wall.

If you’re using Lepotec motion sensor lights, placement becomes even easier — because these lights can be installed without any wiring. Simply use the included magnetic strip, and you can reposition or recharge them anytime.

Tip: For best lighting results, install the lights about 2 inches from the cabinet front edge.

Step 4: Consider Light Spacing

If you’re installing several lights, spacing matters too. Here’s a quick rule of thumb:

• Leave 1 to 2 inches of space between two lights if you’re placing them side by side.

• If your cabinets have gaps or open shelves, treat each cabinet section as a separate zone.

The goal is to have consistent lighting from one end to another, with no dim spots in between.

Step 5: Choose the Light Type (and Why Lepotec is a Great Choice)

There are many types of under cabinet lights — wired, plug-in, or battery-operated. But rechargeable motion sensor lights like those from Lepotec offer the best combination of flexibility, energy efficiency, and modern design.

Why homeowners love Lepotec lights:

• Rechargeable: No need for disposable batteries. Just recharge using a USB cable.

• Motion Activated: Automatically turns on when you walk by — perfect for late-night kitchen visits.

• Long Battery Life: Lasts weeks on a single charge, depending on usage.

• Easy to Install: No wiring required — attach with the included magnet strip.

• Stylish Aluminum Design: Sleek, modern, and fits any décor.

These features make Lepotec under cabinet lights perfect not only for kitchens, but also for closets, pantries, hallways, garages, and even bathrooms.

Step 6: Match Light Brightness to Space Size

Brightness is measured in lumens, and it should match the area you’re lighting. Here’s a quick guide:

If you’re not sure how bright you want it, go with a Lepotec light with adjustable brightness — that way, you can dim it for ambiance or turn it up for tasks like cooking or reading.

Step 7: Don’t Forget Color Temperature

Color temperature affects the atmosphere of your space:

• Warm white (2700K–3000K) gives a cozy, soft glow.

• Neutral white (4000K) is great for everyday use — bright yet comfortable.

• Cool white (5000K–6000K) offers crisp light, ideal for task lighting.

Many Lepotec models come with adjustable color temperature, so you can switch between warm and cool tones depending on your mood or setting.

Example Setup for a Modern Kitchen

Let’s say your kitchen has three cabinet sections:

• A 36-inch main counter

• A 24-inch side counter

• A 12-inch corner cabinet

Here’s a perfect setup using Lepotec lights:

• Two 15-inch lights for the main counter

• One 12-inch light for the side counter

• One 7.8-inch light for the corner

This combination ensures consistent brightness, seamless design, and zero dark spots — all without running a single wire!

Choosing the right size of under cabinet lighting doesn’t have to be complicated. Start by measuring your cabinets, then select the light length and brightness that match your needs.
