We have just completed a refrigerator lighting retrofit project that specifically addresses the long-standing pain points of traditional freezers — uneven illumination, high energy consumption, poor product display, and difficult maintenance. Through customized fixture combinations, scientifically designed lighting layouts, energy-efficient and stable product performance, and comprehensive after-sales support, we have created a premium frozen food display environment that empowers brick-and-mortar supermarkets to capture peak summer traffic and achieve steady sales growth.
Project Background &Pain Points
A couple of days ago, we met with a supermarket owner. He told us that summer is here — ice cream and chilled beverages should be in their peak season right now, just like every year. But sales are down this year. He proactively reached out for a professional commercial freezer lighting upgrade, hoping to boost sales by optimizing the display lighting.
We applaud this owner’s insight. He identified the root cause — commercial freezer lighting — rather than relying on the usual playbook of discounts and promotions. Those tactics only provide a temporary fix, not a lasting solution.
We conducted an on-site assessment of the store and identified 3 core pain points:
- Uneven lighting inside the multi-deck showcase opened especially the top shelf, which is almost completely dark.
- Chest freezers storing ice cream and frozen meat have no dedicated lighting at all — they rely entirely on the store’s ceiling lights, which fail to attract customers.
- The existing fixtures came bundled with the freezer units — mediocre quality, and after-sales support is nearly nonexistent.
Core Upgrade Requirements from the Client
Uniform illumination: Eliminate all dark spots and dead zones inside the refrigerator display showcase— achieve even, full-cabinet light coverage.
Enhanced product appeal: Use high-quality lighting to faithfully reproduce the true color and texture of beverages, ice cream, and frozen meat — making products more enticing and driving impulse purchases.
Easy installation: No cabinet modification needed. Quick to install, with hassle-free fixture replacement and maintenance down the road.
Energy efficiency: The store’s freezers run nearly 24/7. Low power consumption and high light output significantly reduce long-term electricity costs.
Laidishine Lighting Solution
Based on the distinct structural characteristics and display needs of vertical open-front freezers and horizontal chest freezers, we design tailored lighting solutions for each.
Multi-deck showcase opened: shelf Light + canopy Light Combination
The biggest pain point of the air curtain cabinet is the dim lighting on the top shelf. That’s why we deployed the SPU series. It uses lens technology to focus light precisely on the products — zero wasted light. Its half-aluminum, half-plastic housing features a built-in aluminum rail for excellent heat dissipation, effectively suppressing light decay over time.
The vertical lights come in left, center, and right configurations. The SRL series is a cost-effective, dedicated low-voltage fixture for freezers, also equipped with a precision lens optical system that delivers focused, soft, and evenly distributed light. The full-plastic body design ensures lighting performance and electrical safety while significantly reducing procurement costs. Given the longer form factor of pillar lights, they are secured with screws for a stable, wobble-free fit — built for continuous long-term operation.
The canopy lights come with magnetic mounting brackets — no tools required for quick installation and removal. This greatly simplifies the setup process and makes later maintenance and fixture replacement fast and efficient, substantially reducing store operational costs. The entire lighting system is compatible with Laidishine’s one-to-five dedicated wiring harness, ensuring clean, organized cabling — eliminating the messy wiring typical of traditional setups — for safer and more aesthetically pleasing installations.
Island cabinet: SLK Series
Island cabinets hold products like ice cream and frozen steaks — with a wide variety of packaging. That means the lighting needs a high color rendering index to maximize product display appeal. On top of that, light concealment and visual comfort are critical.
Balancing display performance with customer experience, we selected the SLK series — a dedicated hidden fixture for chest freezers, installed recessed beneath the freezer’s handrail.
This hidden installation completely eliminates direct glare and the clutter of exposed fixtures, delivering a clean, premium-looking cabinet exterior. Meanwhile, the SLK series features three core advantages: low power consumption, high light efficiency, and high CRI — evenly brightening every product inside and making colorful packaging truly eye-catching.
Final Results
After the complete lighting upgrade, the overall display quality of the supermarket’s freezers improved dramatically — the product presentation looks completely refreshed, and the client is highly satisfied with the results. The entire solution perfectly matches every store requirement, and compared to the original factory-installed fixtures, the core advantages stand out clearly:
- Energy-efficient & long-lasting stable operation: Low-power, high-output fixtures are perfectly suited for freezers running 24/7, effectively reducing daily power consumption and saving long-term electricity costs for the store.
- High CRI for true-to-life color reproduction: All fixtures feature CRI > 90, faithfully restoring the natural color and translucent texture of beverages, ice cream, and frozen products — softening the cold, sterile feel of the display while elevating product perception and effectively stimulating customer purchase intent.
- Ultra-simple installation, lower maintenance costs: Magnetic quick-mount + hidden installation design means zero cabinet modification, fast setup, and effortless future inspection and replacement — saving time, labor, and operational maintenance costs.
- Extended warranty, worry-free after-sales: All fixtures come with a 5-year warranty, completely resolving the pain point of poor after-sales support from original factory lights, and providing stable lighting support for the store’s everyday operations.
More and more retailers have come to realize the importance of commercial freezer lighting — especially in summer, when chilled beverages are a seasonal impulse-buy category. The display atmosphere and product texture created by lighting directly shape customers’ purchase intent, making it a critical detail for boosting store conversion rates.
