GGD-QC-A belongs to the high-pole lamp series and is specially designed for large-scale lighting in places such as ports, large squares, and sports venues. The lamp poles are usually polygonal conical steel structures (such as 16-sided), treated with hot-dip galvanizing for corrosion protection. The internal lamps mostly adopt high-power LED spotlights, featuring high luminous efficiency (the overall luminous efficiency can reach over 90 lm/W) and long lifespan (more than 50,000 hours). The system is usually equipped with an electric lifting device for easy maintenance, and the lamp has a high protection level, capable of adapting to various harsh outdoor environments.
