January 29, 2026, Shenzhen, China – SED (Shenzhen Smart Electronics Design Co., Ltd.), a professional LED lighting manufacturer with 16 years of expertise, was honored to host a distinguished visit from Wegeret Construction, Ethiopia, represented by Ms. Mahlet and Mr. Demana. This visit provided an excellent opportunity to showcase our advanced production capabilities and stringent quality control systems dedicated to manufacturing high-quality lighting products.

A Legacy of Quality and Innovation

*SED logo - 16 years of excellence in LED lighting.*

Founded in 2010, SED has grown into a reliable partner in the global LED lighting supply chain. Our commitment to innovation, durability, and precise manufacturing processes ensures we meet the diverse needs of our international clients, particularly in demanding sectors like construction and infrastructure development, which Wegeret Construction represents.

Comprehensive Tour of Our Manufacturing Facilities

Our guests embarked on a detailed tour of our production plant, witnessing firsthand the technology and processes behind our products.

1. Core Production & Assembly

Our automated SMT (Surface Mount Technology) machines ensure precise and efficient PCB assembly.

The tour began at the heart of our production: the SMT (Surface Mount Technology) and packaging lines. We demonstrated how our state-of-the-art automated equipment ensures high-speed, consistent, and reliable assembly of circuit boards, which form the core of our intelligent and durable lighting solutions.

2. Rigorous Quality Assurance & Testing

Quality is embedded in every step. We showcased our comprehensive testing laboratories.

• Photometric and Electrical Testing:
  *The VOLNIC-8000 system delivers accurate data on lumens, color temperature, and electrical efficiency.*
  Our advanced Integrating Sphere and the VOLNIC-8000 Comprehensive Photoelectric Testing System precisely measure key parameters such as luminous flux (lumens), color temperature (CCT), color rendering index (CRI), and power efficiency, guaranteeing every product meets its specified performance.

• Environmental Durability Testing:
  The salt spray test chamber simulates harsh corrosive environments for product validation.
  In our Salt Spray Test Chamber, we simulate years of exposure to harsh, corrosive environments. This test is crucial for products destined for coastal or industrial areas, like those in construction projects, ensuring our housings and finishes offer exceptional corrosion resistance and long-term reliability.
  
  

• Specialized Component Testing:
  
  The EL (Electroluminescence) inspection machine identifies micro-cracks and defects in solar panels.
  For our solar-integrated and outdoor lighting solutions, we utilize specialized equipment like the Solar Panel EL (Electroluminescence) Testing Machine. This non-destructive test uses infrared imaging to detect hidden cracks or defects in solar cells, ensuring only components with perfect integrity are used in our systems.
  

Building Future Partnerships

Productive discussions were held to explore project-specific requirements and solutions.

The visit concluded with in-depth technical discussions. Our engineering and sales teams presented tailored lighting solutions that align with Wegeret Construction's project requirements, focusing on energy efficiency, durability for the Ethiopian climate, and smart control options.

"We are deeply impressed by the scale, automation, and particularly the meticulous quality control philosophy at SED's factory," said Ms. Mahlet from Wegeret Construction. "Seeing the rigorous testing, from the integrating sphere to the salt spray chamber, gives us great confidence in the longevity and performance of the products for our construction projects."

Looking Ahead
