Choosing the Right LED for Vertical vs. Horizontal Showcases

Choosing the Right LED for Vertical vs. Horizontal Freezers

Why does one-size-fits-all lighting not work for refrigeration？

Have you ever opened a freezer at the supermarket and thought, “Why is it so hard to see what’s inside?” That’s not just an old bulb issue—it’s a mismatch between lighting and showcase design.

At Laidishine, a Commercial Refrigerated Showcase lighting supplier with global reach—we’ve helped businesses overcome a common challenge: how to make food look fresh, bright, and appealing, no matter the freezer type.

Here’s what we’ve learned about choosing the right LED refrigeration lighting for different display cases.

Vertical Freezers: Focus on Uniform Coverage

Vertical freezers typically hold packaged goods, frozen meals, or ice cream behind glass doors—requiring precision in freezer lighting design.

🔹 Lighting goal: evenly illuminate every shelf, top to bottom
🔹 Best solution: LED tube lights with high CRI (Color Rendering Index >90), mounted vertically along the door frames or mullions
🔹 Why it works: It reduces shadows and gives every product—from the top freezer pizza to the bottom bag of peas—a fair shot at catching the customer’s eye

One of our retail clients recently told us: “After switching to your vertical freezer lights, we saw fewer complaints about ‘dark freezers’ and more customers spending time browsing frozen goods.”

Horizontal Freezers: Angle is Everything

These are the chest-style or island-style coolers often used for frozen seafood, meats, or promo items.

🔹 Lighting goal: direct light down into the open-top display without glare or hot spots
🔹 Best solution: SPU-HB series or angled shelf light LED bars installed inside the upper frame or canopy
🔹 Why it works: These lights cast illumination inward at a controlled beam angle—perfect for enhancing product visibility in horizontal refrigerated display lighting applications

What to Consider When Choosing LED for Any Showcase

• Beam angle: Narrow for focus, wide for coverage
• Color temperature: Warmer (3000K–4000K) for meats, cooler (5000K–6500K) for dairy or seafood
• Moisture and IP rating: Use waterproof LED light solutions (IP65 or higher) in humid or frosty environments like cold rooms
• Installation: For adjustable shelving, choose options like magnetic backs or clip-in models that make reconfiguration easy
