In summary, Beauty STC’s LED E26 base bulbs combine high lumens per watt, exceptional color rendering (CRI >90), and appropriate IP-rated options for diverse applications—all backed by our reputation for engineering precision and long-lasting quality.
Factory Tour: Manufacturing Excellence
Beauty STC’s manufacturing facility in Jiangmen, China, serves as a core production hub for the company’s LED lighting solutions, including its E26 base bulb product line. The factory is designed to support high-volume, precision manufacturing with a strong emphasis on quality control and process efficiency, essential for competitive LED lighting production. Its layout integrates modern SMT assembly lines, dedicated testing zones, and packaging areas within a climate-controlled environment to ensure consistent component handling and product reliability.
The SMT (Surface Mount Technology) assembly process forms the backbone of LED bulb production at the Jiangmen facility. The factory utilizes multiple high-speed, multi-head SMT placement machines, typically from established brands like Yamaha or Siemens, capable of handling the fine-pitch components common in modern LED drivers and control circuits. These lines operate with high placement accuracy, often achieving tolerances under ±0.05mm, and feature automated component feeding systems for reels and trays. Pre-solder paste application is performed via precision stencil printers, while post-placement automated optical inspection (AOI) systems rigorously check component placement, polarity, and solder paste quality before the boards proceed to reflow soldering ovens. This automated SMT infrastructure ensures the high-speed, repeatable assembly required for cost-effective LED bulb manufacturing while minimizing human error.
Aging and reliability testing represent a critical quality gate within the Jiangmen factory’s workflow. Completed LED E26 bulbs undergo mandatory aging tests before final packaging and shipment. These tests typically involve operating the bulbs at rated voltage under controlled thermal conditions for a minimum duration of 24 to 48 hours, simulating extended use to identify early-life failures or component weaknesses. The aging racks are designed for high capacity, often incorporating constant current drivers to ensure stable test conditions. Statistical process control (SPC) data is collected during aging, and any units exhibiting lumen depreciation beyond specifications, color shift, flicker, or complete failure are quarantined for root cause analysis. This rigorous burn-in process significantly enhances field reliability and reduces warranty returns for end customers.
Beauty STC possesses well-established OEM capabilities specifically tailored for LED E26 base bulbs at the Jiangmen facility. The company supports full turnkey OEM solutions, beginning with collaborative design reviews based on client specifications for lumen output, color temperature, CRI, dimming performance, and physical form factor.
