卡塔尔采购需求：太阳能路灯

I'm interested in your integrated solar street lamp with a 5-year warranty and IP67 rating. Could you please provide the pricing details for an order of 50 units? Additionally, I'd like to know about the specifications, shipping options, and any bulk purchase discounts that are available. If possible, please include lead times for order fulfillment as well. I'm looking forward to your prompt response so we can move forward with this potential order. Thanks!
