Factory Tour: Manufacturing Excellence
Beauty STC’s Jiangmen factory serves as our primary manufacturing hub for advanced LED lighting products, strategically located within the Pearl River Delta region to leverage strong supply chain infrastructure and skilled labor. The facility spans over 20,000 square meters and operates under strict ISO 9001 quality management standards, with dedicated clean rooms for precision electronics assembly.
Our SMT production lines are anchored by multiple high-speed Yamaha YS24 series placement machines, complemented by older Yamaha YS12 models for specialized or lower-volume runs. These systems handle components down to 0201 metric size with ±25µm placement accuracy, essential for densely packed COB (Chip-on-Board) lighting strips. The lines integrate fully automated solder paste printers, nitrogen-reflow ovens to minimize oxidation, and 3D AOI systems for real-time solder joint inspection. For COB strip production specifically, we utilize custom feeders and vision systems optimized for flexible PCB handling, ensuring precise die placement and wire bonding alignment critical to lumen uniformity.
Aging and reliability testing are rigorously enforced across all COB lighting strip batches. Every production run undergoes mandatory 24-hour continuous burn-in at 1.2x rated voltage in temperature-controlled chambers (45°C ambient). For clients requiring enhanced validation, we offer accelerated 72-hour aging with thermal cycling between -20°C and 60°C. Each strip is monitored via automated photometric sensors tracking lumen maintenance, chromaticity shift, and thermal performance at 15-minute intervals. Failures trigger immediate root-cause analysis with our in-house LED physics lab, where we perform cross-sectioning and SEM analysis of solder joints or phosphor degradation. Statistical process control data from these tests is shared with OEM partners via our cloud-based quality portal.
Regarding OEM capabilities for COB lighting strips, our Jiangmen facility offers end-to-end customization from concept to packaged product. We support client-specific requirements including custom lengths (50mm to 5m per reel), CRI 80-98 options, CCT ranges from 2200K to 6500K, and specialized beam angles via secondary optics integration.

Application Scenarios
Cob lighting strips are ideal for environments where uniform, glare-free illumination with a high quality of light is essential. In hotels, these strips are particularly effective in guest rooms, hallways, and lobbies where a soft, continuous light enhances the ambiance. Their seamless light distribution makes them perfect for cove lighting, under-cabinet lighting in hotel suites, and indirect lighting in reception areas. The warm and consistent glow contributes to a welcoming and luxurious atmosphere, which is critical in hospitality settings.
In malls, cob lighting strips are well-suited for display lighting, signage backlighting, and architectural highlighting. Their ability to produce a smooth, shadow-free beam makes them excellent for illuminating retail displays, fashion boutiques, and feature walls without the distracting dots or striations commonly seen with traditional LED strips. They can also be used in escalator soffits or ceiling coves to guide customer movement with a modern, elegant glow.
For offices, cob lighting strips are beneficial in meeting rooms, reception areas, and under-shelf or task lighting applications. They provide a clean, professional appearance and reduce eye strain due to their uniform light output. In open-plan offices, they can be integrated into suspended ceiling details or partition coves to create a balanced ambient light that supports productivity and comfort.
When installing cob lighting strips, ensure the mounting surface is clean, dry, and smooth to promote proper adhesion. Always use a constant current or constant voltage driver that matches the specifications of the cob strip to prevent flickering or premature failure. It is advisable to install the strip with a diffuser or lens to further enhance light uniformity and protect the delicate circuitry. Avoid sharp bends and never cut the strip except at designated cut points. For optimal thermal management, mount the strips on aluminum channels which also act as heat sinks—this is especially important in enclosed spaces or high ambient temperature environments. Finally, test the installation before finalizing the setup to confirm consistent brightness and color temperature across the entire run.
