How to Choose LED Strips for Display Cabinets? We’ll Show You the Answer Through a Real Project
If you're looking for LED strips for display cabinets, you’ve probably already Googled these questions:
Can display cabinet LED strips be customized in length?
How do you install display cabinet LED strip to make them look aesthetically pleasing?
Why do many LED strips show visible dots when installed in display cabinets?
Do display cabinet LED strips always need to be paired with aluminum profiles?
Can the connections be small enough to be hidden?
Which is better for display cabinets: COB or SMD?
Can you cut display cabinet LED strips yourself? What’s the best way to cut them to save material?
These questions may seem simple, but they all have one thing in common:
There is no one-size-fits-all solution for display cabinets. The best results often come from custom solutions.
Today, we’re sharing a customer case that started with these very questions and ultimately resulted in a complete, beautiful, and easy-to-install display cabinet LED strip solution.
When the client first reached out, they brought up one of the most common questions from other customers:
“Can display cabinet LED strips be customized? What if the dimensions are non-standard?”
Display cabinets often have unique sizes:
Some need 783mm, others 612mm, or 432mm — each segment is different.
Standard 0.5m, 1m, or 2m LED strips simply won’t fit.
We assured the client:
Yes, customization is possible, and it’s one of our strengths.
We can design the length, color temperature, voltage, connector orientation, and soldering positions to fit the specific cabinet structure.
Our clear and professional response led the client to decide to visit our company for further discussions.
During the meeting, the client asked:
"Is COB or SMD better for display cabinets?" This is a common dilemma for many display cabinet users.
We had the client compare the two types of LED strips on-site:
SMD LED Strips:
Noticeable dot patterns
In transparent or glass cabinets, the light points are easily visible
Requires deep aluminum profiles to reduce light spots
SMD LED Strip with Obvious Light Dots
COB LED Strips:
Continuous light with no visible dots
Cleaner lines and a more sophisticated visual effect
COB is nearly always used for display cabinets, glass showcases, and branded counters
"I want COB; it looks like a continuous light strip." The clearer the solution, the faster the proposal was finalized.
This is one of the top 3 questions on Google.
We explained it very straightforwardly:
Aluminum profiles are not just for aesthetics; they serve three core purposes:
✔ ① To Make the Light More Even (Especially to Prevent Visible Light Dots)
Even with COB, if it’s directly attached to a glass panel or reflective surface, light strip reflections may occur.
Using aluminum profiles + diffusers can help soften the light and make it more uniform.
✔ ② To Make the LED Strips More Durable and Extend Their Lifespan
Display cabinets are environments with long operating hours and high usage frequency.
Aluminum profiles help with heat dissipation, ensuring the LED strips last longer.
✔ ③ To Make Installation Cleaner and More Professional
aluminum channel for led strips can:
Hide the back of the LED strip
Conceal wiring
Make the cabinet look more polished and sophisticated
After seeing several types of aluminum profiles on-site, the client chose the deep-profile aluminum track that most effectively hides the light dots.
In a nutshell: Using aluminum profiles for display cabinet LED strips is not optional — it’s a necessity.
Shallow Aluminum Profile Deep Groove Aluminum Profile
This is one of the most common questions from display cabinet users:
“What if the LED strip connections are too large?”
“Can the connections for display cabinet LED strips be made smaller?”
The standard 2-pin DC male/female connectors, though widely used, have several drawbacks:
They are bulky; Difficult to hide in narrow cabinet spaces; Often stick out, affecting the overall appearance
Can get in the way of the back panel or aluminum profile.
The client’s biggest concern was that the connectors would be “half-visible” and detract from the aesthetics.
Our solution: Use smaller DuPont connectors
The advantages of DuPont connectors were immediately clear: Extremely small in size; Can be completely hidden behind aluminum profiles or the back panel; Clean wiring with no bulging; Excellent visual effect; Requires minimal installation space.
After showing the client a physical comparison, he immediately decided to go with the DuPont solution.
He said: “This is exactly what I was looking for — the smaller, the better.”
The client also asked a highly searched question on Google:
“Do display cabinet LED strips need a separate switch, or should we use a power supply with a built-in switch?”
If a separate switch is used, it would result in:
An extra connection cable; An additional accessory; Difficulty hiding the switch; More complicated installation.
Therefore, we recommended: Using a power supply with a built-in inline switch
The advantages are clear: No need for an additional switch; One cable handles all control; Clean and aesthetically pleasing; Faster installation
More intuitive to use.
After hearing this, the client immediately adopted the solution.
We always stick to the principle:
A good solution isn’t about adding more accessories — it’s about reducing the hassle.
The client then placed a repeat order and asked:
"Can I cut the LED strips myself?"
"Will cutting the strips damage them?"
"How can I cut them to minimize waste?"
We explained: All LED strips can be cut, but cutting too much would lead to waste.
So we proposed a more economical and flexible solution: Buy a 50-meter full roll of COB and cut it on-site
50M Full Roll COB Strip
Marked Cut Points On Light Strip
The benefits were numerous:
Cut as much as needed, without limitations on the initial length; Consistent color without color variation between batches; Can accommodate any irregular length; Minimized waste; Lower cost compared to buying individual strips.
The client hadn’t considered this option before and said: “This gives us more freedom and saves money too.”
In this project, we didn’t just sell LED strips — we addressed each of the client’s most common practical concerns:
✔ Can display cabinet LED strips be customized?
✔ Should we use COB or SMD?
✔ How can we make the LED strips look smooth without visible dots or pixelation?
✔ Do we need aluminum profiles? Which one should we choose?
✔ How can we hide the large connectors? Is there a smaller option?
✔ How can we reduce installation difficulty?
✔ Does the power supply need a switch?
✔ Can the LED strips be cut? How to cut them without wasting material?
✔ Which length of LED strips saves more money?
We solved all of these issues in a single collaboration.
The client later told us:
"You made the entire process of lighting the display cabinet so much simpler." That’s the highest compliment we could receive.
