哥伦比亚采购需求：LED灯，LED灯，壁灯，别墅灯，射灯，吊灯

I'm interested in getting more information about the jhan product line. Specifically, could you share details regarding the various models available, including their specifications and features? Additionally, I would appreciate insights into the production process and any materials used. Understanding these elements will help me assess how they align with our requirements. Also, if you could provide pricing information, including any bulk order discounts, along with lead times for delivery, that would be very helpful. I'm looking to make a purchasing decision fairly soon, so any brochures or product data sheets you have would be great to review as well. Thanks in advance for your assistance!
