Factory Tour: Manufacturing Excellence

Beauty STC Manufacturing Co., Ltd. operates a modern, vertically integrated manufacturing facility in Jiangmen, Guangdong Province, China. This factory serves as a core production hub for our LED lighting products, including high-volume lines for standard and custom solutions. The facility is designed to stringent international quality standards, holding ISO 9001 and IATF 16949 certifications, ensuring robust processes from component procurement through final assembly and testing. Our Jiangmen site features extensive cleanroom environments specifically designated for SMT operations and sensitive assembly stages, critical for LED product reliability.
The Surface Mount Technology (SMT) production capability forms the backbone of our manufacturing efficiency and precision. We deploy multiple high-speed Fuji NXT III SMT lines, each capable of placing components down to 0201 package size with exceptional accuracy. These lines handle the full spectrum of components required for LED drivers and control circuits, including resistors, capacitors, ICs, and MOSFETs. The setup includes automatic optical inspection (AOI) stations integrated directly after placement to verify component alignment, polarity, and solder paste volume in real-time, significantly reducing defect escape rates. This automated SMT infrastructure allows us to achieve high throughput while maintaining the tight tolerances necessary for consistent LED driver performance and thermal management in finished bulbs.
Rigorous aging and reliability testing is a non-negotiable phase in our production flow, particularly for critical items like the 20W LED bulb. Every production batch undergoes a mandatory 24-hour continuous aging test under controlled thermal stress conditions. Units are powered at full rated load within environmental chambers maintained at a constant 55°C ambient temperature, simulating accelerated real-world operating stress far beyond typical room conditions. During this period, automated systems continuously monitor and log critical parameters including forward voltage, current draw, lumen output stability, and thermal performance at designated heat sink points. Any unit exhibiting parameter drift beyond our strict acceptance criteria is automatically rejected and quarantined for root cause analysis. This comprehensive burn-in process effectively identifies infant mortality failures before products leave the factory, ensuring only units with proven initial reliability reach our customers.
Our OEM capability for the 20W LED bulb is highly developed and flexible, supporting diverse client requirements. We offer complete turnkey manufacturing where clients can specify key parameters such as exact lumen output (typically ranging from 2000lm to 2400lm at 150lm/W efficacy), correlated color temperature (CCT) options from 2700K to 6500K, and Color Rendering Index (CRI) levels of Ra>80 or Ra>90. Customization extends to mechanical design elements including heat sink geometry for specific thermal targets, base types (E26, E27, B22), and diffuser materials affecting beam angle. We integrate various dimming protocols including TRIAC, ELV, 0-10V, and DALI upon request. Clients can provide their own driver schematics for manufacturing or leverage our in-house engineering team to develop optimized thermal and electrical solutions meeting target cost points and regional safety certifications like UL, ETL, CE, TÜV, and CCC. Our Jiangmen factory manages all aspects including component sourcing against approved vendor lists, SMT assembly, aging, final optical and electrical testing, packaging configuration, and branding with client-specific labels or laser marking. This end-to-end control ensures consistent quality and scalability for both large-volume contracts and specialized low-volume runs.
Application Scenarios

A 20W LED bulb is an energy-efficient lighting solution that provides bright illumination while consuming significantly less power than traditional incandescent or halogen bulbs. It typically delivers a light output equivalent to a 100W to 150W incandescent bulb, making it suitable for a wide range of commercial and public applications.
In hotels, 20W LED bulbs are ideal for use in lobbies, hallways, guest room reading lights, and reception areas where consistent, warm, and inviting illumination is desired.
