Technical Specs & Certifications
LED COB (Chip-on-Board) lighting represents a significant advancement in solid-state illumination, offering superior optical control and thermal management compared to traditional multi-die LED arrays. At Beauty STC Manufacturing Co., Ltd., our engineering focus ensures these specifications meet rigorous commercial and industrial demands while maintaining exceptional quality control throughout production.
Lumens per Watt (lm/W) efficiency is a critical metric for operational cost and sustainability. Beauty STC’s high-performance COB modules typically achieve 130-160 lm/W under real-world operating conditions at 25°C ambient temperature. This range reflects our strategic balance between efficacy and longevity, utilizing premium 3030 or 3535 SMD chips with optimized phosphor conversion. Importantly, our thermal management system—featuring copper-core MCPCBs and proprietary heat-sinking designs—minimizes lumen depreciation at elevated temperatures. Unlike competitors who quote lab-only figures, our datasheets specify performance at 65°C junction temperature (per LM-80 standards), ensuring customers receive realistic efficiency projections for sustained operation. Binning processes guarantee consistent output within ±5% across production batches.
Color Rendering Index (CRI) exceeding 90 is non-negotiable for applications requiring accurate color representation, such as retail displays, art galleries, and healthcare facilities. Beauty STC achieves CRI Ra >92 consistently through multi-phosphor formulations with elevated R9 values (typically >50) for vibrant red rendition. We go beyond basic CRI by providing TM-30-15 metrics (Rf >85, Rg >100) in our technical documentation, giving designers comprehensive insight into color fidelity and gamut. This precision stems from our in-house phosphor blending facility and spectroradiometer-based calibration, ensuring every COB module undergoes spectral validation before shipment. Our R&D team continuously refines formulations to minimize the efficacy penalty often associated with ultra-high CRI, maintaining lm/W performance within 5-7% of standard CRI 80 equivalents.
IP (Ingress Protection) ratings define environmental resilience, particularly crucial for outdoor, wet-location, or industrial deployments. Beauty STC offers COB solutions across multiple IP tiers: IP20 for standard indoor use, IP65 for protected outdoor fixtures (dust-tight with water jet resistance), and IP67 for temporary submersion applications (1 meter depth for 30 minutes). Achieving these ratings requires holistic engineering—our COB modules integrate seamlessly with silicone-gasketed optics and die-cast housings, while drivers undergo conformal coating for moisture resistance. Notably, our IP67-rated products undergo 1,000-hour salt-spray testing per ASTM B117, exceeding IEC 60529 requirements. We emphasize that IP rating applies to the complete luminaire assembly; thus, we provide detailed integration guidelines ensuring end-users maintain certification during installation.
Beauty STC’s commitment to quality permeates every specification. Our ISO 9001-certified production lines implement six-sigma processes with 100% automated optical inspection (AOI) of COB assemblies. Each module undergoes 48-hour burn-in testing at 75°C ambient, with real-time monitoring of lumen maintenance and chromaticity shift. We provide LM-80 reports exceeding 10,000 hours and TM-21 lifetime projections (L70/B50 > 50,000 hours) validated by third-party labs. Unlike generic manufacturers, we enforce strict traceability—every COB carries a laser-etched serial number linking to raw material certifications (including IECQ-certified chip suppliers) and final test data. This end-to-end quality philosophy ensures our COB lighting delivers not just on-paper specifications, but field-proven reliability under demanding conditions, reducing total cost of ownership through extended service life and consistent photometric performance.

Application Scenarios
LED COB (Chip-on-Board) lighting excels in commercial environments requiring high lumen density, uniform illumination, and precise optical control. Its seamless light emission without visible individual diodes makes it ideal for applications demanding visual comfort and aesthetic integration. Below are specific use cases for hotels, malls, and offices, followed by critical installation guidance based on our engineering standards at Beauty (STC) Manufacturing Co., Ltd.
In hotels, LED COB lighting is strategically deployed where ambiance and functionality intersect. Lobbies benefit from COB-powered linear cove lighting to create soft, shadow-free illumination that enhances architectural features without glare, while COB spotlights in reception areas ensure accurate color rendering for guest interactions. Guest rooms utilize COB strips under cabinet valances or headboards for warm, even ambient lighting at 2700K-3000K, avoiding the pixelation of SMD LEDs. High-end spas and wellness areas rely on COB downlights in wet-rated fixtures for glare-controlled, uniform light that supports relaxation, and COB is essential in retail corridors within the hotel for merchandise displays requiring crisp, shadowless illumination.
Malls leverage COB technology primarily for visual merchandising and spatial definition. COB track lights with narrow beam angles (15°-24°) are critical for jewelry and luxury goods displays, where high CRI (>90) and precise spotlighting prevent hotspots and reveal true product colors. Perimeter cove lighting using COB strips creates expansive, welcoming atriums by washing walls evenly, eliminating the “scalloping” effect of multi-die LEDs. Under-shelf COB modules in department stores provide unbroken task lighting on products, and COB-powered escalator well lighting ensures safe, uniform illumination without distracting shadows. For high-ceiling anchor stores, COB high-bay fixtures deliver focused vertical illuminance where traditional lamps waste light.
Offices implement COB solutions to reduce eye strain and enhance productivity. Open-plan workspaces use COB-integrated troffer panels with diffusers to eliminate glare and provide uniform task lighting at 3500K-4000K, critical for computer-based work. Executive suites and conference rooms employ dimmable COB downlights for circadian lighting support, while COB under-cabinet lighting in kitchenettes offers shadow-free task illumination. Reception desks utilize COB backlit signage for crisp branding visibility, and COB is preferred for library or archive areas requiring high CRI for document accuracy without UV emission.
Installation demands strict adherence to thermal and electrical protocols to maximize COB lifespan and performance. Always verify the fixture’s thermal management capability; COB modules generate concentrated heat, so ensure direct thermal contact between the COB substrate and the heat sink using manufacturer-specified thermal interface material—never install COB into enclosed fixtures not rated for it. Maintain minimum clearance around COB emitters as per datasheets to prevent heat stacking, especially in recessed downlights. For linear COB strips, use constant-current drivers matched to the voltage range and avoid daisy-chaining beyond 5 meters to prevent voltage drop. In high-ceiling mall installations, calculate beam angles precisely using photometric software to avoid spill light; a 36° beam at 10m height requires careful aiming to cover retail displays without illuminating adjacent areas. Always power COB fixtures through a dedicated circuit with surge protection, as voltage spikes disproportionately damage COB arrays versus single-die LEDs. Finally, during commissioning, use a lux meter to verify uniformity—COB installations should show less than 10% variation across the target area to achieve the intended visual effect.
These applications and practices reflect Beauty (STC)’s field-tested approach, ensuring COB lighting delivers its full value in demanding commercial settings while minimizing maintenance callbacks.
