尼日利亚采购需求：太阳能灯杆，太阳能灯杆，太阳能路灯杆

I'm looking for pricing on solar street lights along with their poles in both white and black colors. Could you please provide the cost details for these products? Additionally, it would be great if you could include information about any specifications or features that differentiate your offerings, as I'm particularly interested in their performance and durability. Thanks!
