尼日利亚采购需求：LED天花灯、LED筒灯、LED豆胆灯、LED轨道灯、LED泛光灯、LED射灯

I'm interested in sourcing LED lights that are black in color, specifically with a length of 48 inches. Could you please provide details on your available options, including any variations in design or features? I'm particularly keen on understanding the specifications, brightness levels, and energy efficiency ratings of the products you offer. Additionally, it would be helpful to know about your pricing tiers based on order quantities, lead times for delivery, and any warranty or return policies that accompany the products. If you have a catalog or a product sheet, kindly share that as it would assist in making a more informed decision. Looking forward to your prompt response!
