Technical Specs & Certifications
Dotless LED strip lights are a premium category of linear lighting designed to deliver smooth, continuous illumination without visible individual diodes—ideal for high-end architectural, residential, and commercial applications where visual comfort and design aesthetics are critical. At Beauty (STC) Manufacturing Co., Ltd., our dotless LED strip lights are engineered with precision to exceed industry benchmarks in performance, efficiency, and reliability.
Our dotless LED strips achieve an efficacy range of 100 to 120 lumens per watt, depending on color temperature and density configuration. This high lumens-per-watt ratio ensures energy-efficient operation without sacrificing brightness, making them suitable for both accent and ambient lighting applications. The strips utilize high-density chip-on-board (COB) or dense surface-mounted device (SMD) arrays, often with 5050 or 3535 LEDs spaced at intervals of less than 10mm, creating the seamless “dotless” effect.
Color rendering is a key strength of Beauty STC’s dotless LED technology. All our high-CRI dotless strips deliver a Color Rendering Index (CRI) greater than 90, with options available up to CRI 95+ for applications requiring the most accurate color representation, such as retail displays, art galleries, and healthcare environments. This is achieved through the use of high-quality phosphor coatings and rigorously selected LED bins to ensure consistent chromaticity and minimal deviation across production batches.
In terms of environmental protection, Beauty STC offers dotless LED strips in multiple IP rating configurations. Our standard non-coated strips are rated IP20, suitable for dry, indoor environments. For damp or outdoor applications, we provide IP65-rated strips with a silicone encapsulation that protects against dust and low-pressure water jets. For fully submersible or high-humidity installations, our IP67 and IP68-rated versions are available, with robust silicone overmolding enabling safe operation in underwater settings up to 1 meter depth for extended periods.
Quality is central to Beauty STC’s manufacturing philosophy. Our dotless LED strips are produced in ISO-certified facilities using automated SMT production lines and undergo 100% aging and photometric testing. We use only premium-tier components, including high-conductivity flexible PCBs, high-purity gold-wire bonding, and thermally stable encapsulants to ensure long life—typically rated at L70 >50,000 hours. Each batch is tested for color consistency, lumen output, and thermal performance to ensure reliability across diverse operating conditions.
With superior optical performance, excellent CRI, versatile IP protection, and industry-leading build quality, Beauty STC’s dotless LED strip lights offer a trusted solution for designers and engineers who demand both aesthetic excellence and technical robustness.
Factory Tour: Manufacturing Excellence
Beauty STC’s manufacturing facility in Jiangmen, Guangdong Province, serves as our primary production hub for advanced LED lighting solutions, including our proprietary dotless LED strip lights. This modern factory integrates state-of-the-art equipment with stringent quality control protocols across approximately 20,000 square meters of dedicated manufacturing space. The facility is designed for high-volume production while maintaining flexibility for specialized OEM projects, supported by a workforce trained in precision electronics assembly and optical engineering.
Our SMT (Surface Mount Technology) production line forms the backbone of dotless LED strip manufacturing. We operate multiple high-speed JUKI FX-3 series placement machines capable of handling ultra-miniature 0201 components at placement accuracies of ±0.05mm. These machines are specifically configured for the unique demands of dotless technology, featuring specialized vision systems to align micro-LED chips at sub-millimeter intervals and precise solder paste deposition for thermal management. The line includes nitrogen-reflow ovens with 10-zone temperature profiling to ensure consistent solder joints for the densely packed LED arrays, critical for achieving the seamless illumination effect without visible dots. All SMT processes undergo real-time automated optical inspection (AOI) to verify component placement and solder quality before proceeding to subsequent stages.
Aging testing is a non-negotiable phase in our dotless LED strip production. Every reel undergoes a minimum 72-hour continuous aging cycle under controlled thermal and electrical stress conditions. This occurs in dedicated environmental chambers maintained at 65°C ambient temperature with 85% relative humidity, simulating accelerated real-world usage. We implement a dual-phase aging approach: initial aging immediately after SMT assembly to identify early-life failures, followed by final aging after final assembly and packaging. During testing, strips operate at 110% of rated voltage while our monitoring systems track lumen maintenance, color consistency (Δuv’ < 0.003), and thermal performance. Units exhibiting even marginal deviations in light output uniformity—critical for dotless technology—are automatically rejected, ensuring only strips meeting our 0.95+ uniformity standard reach customers.
For OEM partnerships focused on dotless LED strip lights, our Jiangmen factory provides comprehensive customization capabilities. We support full specification tailoring including lengths from 0.5m to 100m per reel, CCT ranges from 1800K to 6500K with CRI >90, and custom silicone encapsulation profiles for specific beam angles. Our engineering team collaborates with clients on circuit design modifications for specialized dimming protocols (0-10V, DALI, PWM) and develops application-specific IC programming for unique lighting effects. The facility accommodates private labeling with custom reel packaging, technical documentation in multiple languages, and flexible MOQs starting at 5,000 meters.
