南非采购需求：进近灯光、跑道灯光、滑行道灯光、风锥、LED航海灯、太阳能航海灯

I'm interested in acquiring aircraft warning spheres made from fiberglass-reinforced plastic (FRP). Specifically, I'm looking for a size of about 600mm. It's essential that these products meet industry standards and are suitable for harsh weather conditions, as they play a crucial role in aircraft safety. Could you provide me with detailed specifications, pricing, and available colors? Additionally, I'd appreciate your lead times for production and delivery, as well as any options for bulk purchasing. If you have any certifications or quality assurance processes in place, please include that info as well. Looking forward to your prompt response!
