苏里南采购需求：红绿灯

I'm looking for pricing information on solar traffic lights for an upcoming project. Specifically, I would like to know the different models you offer, their specifications, and whether you have options suitable for various weather conditions. Additionally, it would be great to understand the lead time for orders and any bulk purchase discounts you might provide. Could you also provide details on the warranty and support available for these products? I'm particularly interested in the durability and efficiency ratings, as these factors are crucial for my selection process. If you have any catalogs or brochures that include visual representations and technical details, please send those along as well. Thanks in advance for your assistance!
