斯里兰卡采购需求：一体式太阳能路灯

I'm interested in your solar street light featuring a 5-year warranty and patented design with a power output of 30 watts. Could you provide me with the pricing details for this model? Additionally, I'd like to know the purchasing process—whether I can place an order directly through your website or if there are alternative methods to ensure a smooth transaction. Looking forward to understanding more about the product specifications, shipping options, and any bulk order discounts you might offer. It would be great to get this info as soon as possible so I can make a decision. Thanks!
