南非采购需求：太阳能灯杆，太阳能灯杆，太阳能路灯杆

I'm looking to get more information about your solar street lights. Specifically, I'm interested in the range of features they offer, including brightness levels, battery capacity, and any smart technology options. Also, could you provide details on the materials used, their durability, and any environmental factors they can withstand? Additionally, it would be great to know about the pricing structure and any bulk order discounts you might have. I'm particularly keen on understanding lead times for production and shipping, as well as any warranty or after-sales support you offer. If you have a catalog or a product brochure, please send that along as well. Looking forward to your prompt reply!
