UNIQLO Shanghai Lighting Retrofit | XHLWX Glare-Free LEDs

In the heart of Shanghai's bustling Huaihai Middle Road, the UNIQLO Global Flagship store stands as a multi-story beacon of modern apparel. As a landmark destination for fashion enthusiasts and a key touchpoint for the brand's "LifeWear" philosophy, maintaining a cutting-edge in-store experience is paramount. By 2024, the existing lighting system, a combination of outdated metal halide and first-generation LED fixtures, was no longer aligned with UNIQLO's commitment to quality, sustainability, and customer comfort. XHLWX Lighting was entrusted with the challenge of a comprehensive lighting retrofit, a project designed to redefine the store's ambiance, enhance product presentation, and deliver substantial operational efficiencies.

Project Background & Customer Pain Points

The UNIQLO Shanghai flagship is more than just a retail space; it's an architectural statement spanning over 8,000 square meters across five floors. The previous lighting installation, while functional at its inception, presented several critical pain points that hindered the brand experience and inflated operational overhead.

Excessive Energy Consumption and Maintenance: The legacy fixtures were notoriously inefficient, leading to exorbitant electricity bills and a significant carbon footprint. Furthermore, the short lifespan and color degradation of the old lamps necessitated frequent and disruptive maintenance, pulling staff away from customer-facing activities.
Compromised Visual Merchandising: For an apparel giant like UNIQLO, color is everything. The existing lighting had a low Color Rendering Index (CRI), which failed to represent the true hues of the fabrics. Vibrant reds appeared dull, subtle pastel tones were washed out, and the crispness of whites was lost. This disconnect between the perceived and actual color of the garments was a direct threat to customer satisfaction and sales.
Poor Shopper Comfort: Glare was a significant issue. Poorly shielded spotlights created harsh reflections and visual noise, forcing customers to squint and detracting from a comfortable browsing experience. The ceiling was a chaotic array of bright spots, pulling attention away from the meticulously curated product displays on the floor.
Operational Inflexibility: The store's lighting was static. Adapting to new collection launches, seasonal promotions, or changes in store layout was a cumbersome, manual process that required electricians. The visual merchandising team lacked the tools to dynamically shape the store's atmosphere to match their creative vision.

UNIQLO sought a partner who could deliver not just fixtures, but a holistic lighting solution—one that would solve these pain points and elevate the flagship store to a new global standard.

Our Lighting Solution: Precision and Aesthetics

XHLWX Lighting's proposal was built on a foundation of precision optics, superior light quality, and intelligent control. Our goal was to create a harmonious and dynamic environment where the light serves the merchandise, enhances the architecture, and prioritizes customer comfort.

The design was centered around a layered lighting approach using a carefully selected portfolio of our most advanced fixtures:

Primary Workhorse - XHLWX-ProTrack™ T95 Series: Over 2,500 units of our premier track spotlight were deployed. This fixture was chosen for its exceptional performance characteristics: a CRI of over 95 with a high R9 value for rich reds, deep-recessed COB technology with a unique black reflector, and a suite of optical accessories. Interchangeable lenses allowed us to craft precise beam angles, from a narrow 15° for accenting mannequins to a wider 38° for general displays.
Ambient & Circulation - XHLWX-Focus™ ABL Gen3: For walkways, fitting rooms, and lower-ceiling areas, our adjustable anti-glare downlights provided a soft, uniform ambient foundation. Their minimal trim and deep-regressed light source ensure they blend seamlessly into the ceiling, contributing to a clean and uncluttered architectural feel.
Integrated Illumination - XHLWX-LinearFlow™ DL2: To add depth and eliminate shadows, our high-efficacy linear LED strips were discreetly integrated into shelving units, cove ceilings, and behind the iconic UT (UNIQLO T-shirt) display walls. This provided gentle vertical illumination that makes the space feel larger and more inviting.

We standardized the entire installation on a 4000K color temperature. This choice delivers a clean, vibrant, and contemporary feel that aligns with the UNIQLO brand, ensuring colors are rendered accurately without the cold, clinical feel of higher CCTs or the overly warm, dated feel of 3000K.

Technical Highlights

Three core technical pillars distinguished our solution and were key to achieving the project's ambitious goals.

1. Exceptional Color Rendition (CRI 95+, R9>90) In fashion retail, what the eye sees must be true. A standard CRI 80 LED might be acceptable for an office, but it fails to accurately render the saturated colors and subtle tones critical to apparel. Our ProTrack™ T95 series utilizes a bespoke LED chip with a specialized phosphor formulation, delivering a light spectrum that closely mimics natural daylight. This results in a CRI exceeding 95 and, crucially, an R9 value (for rendering deep red) of over 90. For UNIQLO, this meant that the vibrant red of a down jacket, the deep indigo of denim, and the nuanced shades of their LifeWear collection were presented with absolute fidelity. This builds subconscious trust with the customer, ensures the product meets expectations outside the store, and ultimately reduces returns.

2. Superior Glare Control (UGR<19) The principle of "seeing the effect of the light, not the source" was central to our design. We engineered the entire merchandise area to achieve a Unified Glare Rating (UGR) of less than 19, a level considered excellent for demanding visual environments. This was accomplished through a multi-faceted approach:

Optical Engineering: The T95 spotlights feature a deep-set light source with a 60-degree shielding angle, physically cutting off the view of the bright LED from normal viewing angles.
Honeycomb Louvers: Every spotlight was fitted with a honeycomb louver accessory. This grid structure acts as a series of micro-baffles, eliminating any peripheral stray light and ensuring a sharply defined beam. The result is a dramatically more comfortable shopping environment. The ceiling plane recedes into darkness, creating a 'theatrical' effect where the illuminated products emerge as the heroes of the space. Shoppers' attention is naturally guided to the merchandise, allowing for longer, more relaxed browsing without visual fatigue.

3. Intelligent Control (DALI-Casambi Hybrid System) To provide both robust management and ultimate flexibility, we implemented a powerful DALI-Casambi hybrid control system.

DALI Backbone: The entire installation runs on a DALI (Digital Addressable Lighting Interface) network. This provides granular, addressable control of every single fixture from a central point. For the facilities management team, it offers detailed energy monitoring, fault reporting, and predictive maintenance capabilities, ensuring the system runs at peak efficiency.
Casambi Flexibility Layer: We integrated the DALI system with a Casambi Bluetooth Mesh wireless layer. This empowers the store's visual merchandising and management teams with intuitive control via a tablet or smartphone app. They can now effortlessly create, save, and recall pre-set lighting scenes for different times of day, special events, or new collection launches. A bright, energetic "Weekend Peak" scene can be switched to a softer, more intimate "Weekday Evening" scene with a single tap. This transforms the lighting from a static utility into a dynamic marketing and branding tool.

Installation and Commissioning

The project's primary constraint was the non-negotiable requirement of zero disruption to the store's business hours. The retrofit of five floors had to be executed entirely at night.

Our project management team developed a meticulous phased rollout plan in collaboration with the general contractor. Work was scheduled from 10 PM to 7 AM, seven days a week, for six weeks. To maximize efficiency within this tight window, we leveraged pre-configuration and logistical planning:

Our fixtures were delivered to the site with DALI drivers pre-addressed according to the lighting plan, eliminating hours of on-site programming.
Track spotlights were fitted with the correct lenses, louvers, and track adapters in our workshop, making them 'plug-and-play' for the installation team.

Our field application engineers were on-site every night, overseeing the physical installation and ensuring every one of the thousands of fixtures was aimed and focused to perfection. Following the physical installation, they commissioned the entire DALI-Casambi system, programming the master schedules, grouping lights into logical zones, and providing comprehensive training to the UNIQLO staff. This hands-on approach ensured a flawless handover and empowered the local team to take full ownership of their new system.

Measured Results & Project Impact

Upon completion, a thorough audit was conducted to measure the project's success against its initial goals. The results were outstanding.

Energy Savings: The data from the DALI control system confirmed a 62% reduction in lighting-related energy consumption compared to the previous installation. This dramatic saving is a result of both the high luminous efficacy of our LED fixtures (averaging 120 lm/W) and the intelligent scheduling and dimming enabled by the control system.
Illuminance Levels: On-site measurements confirmed that our design targets were met with exceptional accuracy. We achieved a vibrant 1200-1500 lux on key mannequins and feature walls, a comfortable 800 lux on general merchandise, and a relaxed 500 lux in circulation paths, creating the desired visual hierarchy.
Light Quality: Spectrometer readings verified a consistent store-wide CCT of 4000K (within a tight ±80K tolerance) and an average CRI of 96.2, confirming the world-class quality of the light.

Beyond the numbers, the qualitative impact was immediately apparent. Store management reported an overwhelmingly positive response from shoppers about the store's bright, open, and comfortable new look. The visual merchandising team praised the way the colors of the collections now "pop," noting that the true-to-life representation of textures and shades has tangibly improved the product's perceived value. The new flexible control system has unlocked a new level of creativity, allowing them to adapt the store's mood in minutes, not days.

This project stands as a testament to how a strategic investment in state-of-the-art lighting technology can simultaneously enhance brand image, improve customer experience, and deliver profound operational and environmental benefits.

FAQ

Q1: Why was a CRI of 95+ so critical for an apparel store like UNIQLO?

A: For apparel, color is arguably the most important factor in a customer's purchasing decision. A CRI of 95+ with a high R9 (red rendering) value ensures that the colors of the garments under the store's artificial light are virtually identical to how they appear in natural daylight. This builds customer confidence, as they know the product will look the same when they leave the store. It prevents dissatisfaction and reduces the rate of product returns due to color discrepancies.

Q2: How does the DALI-Casambi hybrid system benefit the store's day-to-day operations?

A: The hybrid system offers the best of both worlds. The DALI backbone provides robust, centralized control and detailed system-wide data (like energy use and fixture health) for the facilities management team. The Casambi wireless layer, accessible via a user-friendly app, provides incredible flexibility for the on-floor staff. The visual merchandising team can independently adjust lighting scenes for promotions or new layouts without needing an engineer, making the store highly agile and responsive.

Q3: What was the biggest challenge during the installation at such a high-traffic flagship store?

A: The single greatest challenge was logistical: executing a massive, multi-floor retrofit with absolutely no disruption to daytime store operations. This required meticulous night-by-night planning, close coordination with the store's management and other contractors, and maximizing efficiency through factory pre-configuration of our products. Our on-site engineering team's nightly presence was crucial to problem-solve in real-time and ensure the project stayed on its aggressive schedule.
