坦桑尼亚采购需求：太阳能路灯，LED路灯，高杆灯，庭院灯，镀锌灯杆，太阳能标识

I'm looking for street lights in the range of 400 to 800 Watts. Please provide details on the various models you offer within this power range. I'm particularly interested in features such as energy efficiency, durability, and any smart technology options available. If you have variations in designs or materials, I'd love to see those too. Additionally, please include your pricing information, lead times for delivery, and any available warranty or after-sales support. It would also be helpful to know about the installation process and any recommended accessories or components that would work best with these lights. Looking forward to your prompt response!
