Jewelry retailers upgrading from halogen to LED in acrylic display cases face a spec decision that rarely appears in supplier quotes: color consistency across a multi-case installation. A single case looks fine. Twenty cases in a row, each from a different production batch, and the color temperature drift becomes visible to customers walking past. That's the problem this article addresses-along with the other lighting specs that determine whether your display investment performs at retail scale.
At Ouke Acrylic, we've been manufacturing LED-integrated acrylic display cases since 2010. Our longest-running retail account is Chow Tai Fook, where we've supplied acrylic jewelry display trays and counter showcases for their mainland China store network since 2011-currently fulfilling quarterly replenishment orders across approximately 200 locations. That relationship taught us which specs actually matter for jewelry retail and which ones are checkbox items that don't affect floor performance. This article breaks down what we've learned.
Color Temperature: Matching Light to Merchandise
For gold jewelry and warm-toned luxury goods, 2700K-3000K lighting makes metals appear richer. For platinum, silver, and steel watches, 4000K-5000K neutral light brings out surface detail without yellow cast. This is consistent with IES RP-2-20 recommendations for retail display applications.
The question procurement teams face isn't "warm or cool"-it's whether your product mix justifies a single fixed color temperature or a tunable system. Our Acrylic Luminous Display Stand line offers both options: fixed CCT for cost-sensitive deployments, and tunable white (2700K-6500K) for showrooms with rotating inventory. We produce these in-house at our Shenzhen facility, which means we control color consistency to ≤3 SDCM (MacAdam ellipse steps) across production batches-the threshold where adjacent cases in a retail row won't show visible color shift under side-by-side comparison.
CRI: When 90 Is Enough, and When It Isn't
CRI 90 is the industry baseline for retail. CRI 95+ becomes necessary when customers are actively comparing colors against their expectations-lipstick shades, gemstone hues, fabric swatches. The IES TM-30 standard now supplements CRI with the Fidelity Index (Rf) and Gamut Index (Rg) for more precise color rendering evaluation, particularly for LED sources.
Our LED modules use chips rated at CRI 93-95 depending on configuration, with R9 (saturated red) values above 50-the reason reds look muddy in some display cases and vibrant in others. We provide LM-79 test reports on request, so your QA team can verify specs against your internal standards rather than relying on marketing claims.
For most acrylic display case applications-collectibles, electronics, general merchandise-CRI 90 delivers excellent visual quality at a lower component cost. We quote both options with pricing so you can make the tradeoff explicitly rather than defaulting to the highest spec regardless of application.
Thermal Management: The Spec That Protects Your Investment
LED strips generate substantially less heat than halogen-but "less heat" doesn't mean "no heat." In a sealed acrylic enclosure, even moderate heat accumulation causes warping over 12-24 months if thermal dissipation isn't designed into the case.
Every LED-integrated display case we produce includes extruded aluminum profiles that act as heat sinks, drawing thermal load away from the acrylic panels. This isn't an upcharge-it's how we avoid the warranty claims and replacement costs that come from cases warping in the field. The practical difference: our cases maintain dimensional stability at continuous LED operation up to 45°C ambient, which covers most retail and exhibition environments without air conditioning directly on the display.
For UV sensitivity, quality LEDs approach zero UV output-well under the 75 microwatts per lumen threshold used in museum-grade display specifications. If you're displaying vintage collectibles, archival documents, or UV-sensitive merchandise, we include UV output data in our spec sheets rather than asking you to take "low UV" on faith.
Installation Specs That Affect Total Cost
We default to 24V systems for any case dimension exceeding 1.5 meters. Voltage drop across LED runs longer than 5 meters causes visible dimming at the strip's end-24V eliminates the power injection complexity that 12V systems require for uniform brightness, and reduces the number of failure points in the installation.
The other cost driver most RFQs miss: connection point durability. Our LED modules use soldered connections rather than friction-fit pins. Friction-fit fails when thermal cycling loosens the contact; soldered connections don't. The manufacturing cost difference is real, but it's smaller than the cost of a technician visit to rewire a failed connection inside a sealed display after installation. We include power supplies in our integrated case pricing rather than leaving driver sourcing to the installer.
Specifications at a Glance

Working with Ouke Acrylic
Our 3,000 square meter facility in Shenzhen handles design, CNC cutting, laser engraving, LED integration, and quality inspection under one roof. The practical advantage: when a dimension tolerance issue affects LED fit, we catch it at the cutting stage, not after the case ships. That integration is why we can offer prototype MOQ of one unit-we run a dedicated sample line separate from production, so prototype orders don't require batch scheduling.
Our product portfolio includes Acrylic Jewelry Display Boxes, Luminous Display Stands, and LED-integrated display cabinets across dozens of configurations. We also produce fully custom solutions when standard products don't fit-from one-off museum cases to 500-unit retail rollouts.

FAQ
Q: What is your minimum order quantity for LED-integrated display cases?
A: One unit for prototypes and samples-we run a dedicated sample line separate from production, so prototype orders don't require batch scheduling. Production orders typically start at 50-100 units for cost efficiency, but we accommodate smaller runs for specialty applications at a per-unit premium.
Q: What LED specifications do you offer?
A: Standard options include 2700K, 3000K, 4000K, and 5000K fixed CCT, all at CRI 93+ with R9 >50. Tunable white (2700K-6500K) and RGB options are available for custom orders. All modules use LEDs rated for 50,000+ hour lifespan per LM-80 testing standards.
Q: What is your typical production lead time?
A: Samples ship within 3-5 business days. Production orders ship within 15-20 business days after design confirmation, depending on quantity and complexity.
Q: Can you accommodate factory audits?
A: Yes. We host buyer QC teams and third-party inspectors regularly. If you require a pre-production audit or in-process inspection, we'll coordinate scheduling and provide facility access.
Q: What are your payment terms?
A: Standard terms are 30% deposit, 70% before shipment, via T/T. For established accounts or larger orders, we discuss LC or alternative structures. Sample orders are typically paid in full before production.
Q: What happens if delivered units don't match approved samples?
A: We document approved samples with photos and measurements. If production units deviate beyond agreed tolerances, we replace affected units at our cost. Color consistency claims are verifiable against the SDCM spec in our documentation.
Q: What warranty do you offer?
A: 24 months on the complete assembly, covering both acrylic case structure and integrated LED modules. If a case structure defect causes LED failure within the warranty period-such as warping that damages the LED channel-that's covered under the same 24-month term. We don't split warranty periods in a way that creates ambiguity about thermal-related failures.
