In the lighting industry in China, the prestigious “Double Grade A” qualifications—officially known as Lighting Engineering Design Specialty Grade A and Urban & Road Lighting Engineering Professional Contracting Grade 1—represent the highest standards of expertise and capability.
What Are the “Double Grade A” Qualifications?
The Urban & Road Lighting Engineering Qualification is divided into three levels:
- Grade 1: Can undertake all types and scales of urban and road lighting construction projects.
- Grade 2: Limited to projects with a single contract value not exceeding RMB 12 million.
- Grade 3: Limited to projects with a single contract value not exceeding RMB 6 million.
The Lighting Engineering Design Specialty Qualification is divided into Grade A and Grade B:
- Grade A (issued by the Ministry): No restrictions on project type or scale— the highest and most stringent level in the industry.
- Grade B (issued by provincial authorities): Limited to medium and smaller-scale specialty lighting design projects.
According to the latest data from China’s Ministry of Housing and Urban-Rural Development, only 95 companies nationwide hold both qualifications simultaneously. Guangdong Hongyu Lighting Engineering Construction Co., Ltd. proudly stands among them as one of the select few.
