孟加拉采购需求：一体式太阳能路灯

I am looking to purchase 3 units of a high-quality 120w product. It's important that the items meet certain standards to ensure durability and performance. Please provide details on the specifications, materials used, and any certifications your products might have. Additionally, I'd appreciate it if you could share information on pricing, lead times for delivery, and any bulk purchase discounts that may apply. If you have any recommendations or similar products, feel free to include that as well. Looking forward to your prompt response!
