美国采购需求：Dali 驱动器、Dmx 控制器、可控硅控制器、LED 调光器、Dali 调光器、Dali 控制器

I'm looking for a specific product for one of my customers. They need just two units, and I want to see if there are any authorized distributors in the USA where I can purchase them. It would be really helpful to know about any local sources or preferred suppliers that you recommend. If you have any details on pricing, availability, or lead times for this product, that would be great too. Getting this order sorted quickly is essential, so any guidance you can provide would be much appreciated. Thanks for your help!
