加拿大采购需求：手术室设备，包括手术灯、手术台和医用吊塔

I am currently in the market for dual head ceiling surgery lights and would appreciate more detailed information on the options you offer. Specifically, I am interested in models that come equipped with a camera as well as those that do not. It would be great if you could provide me with pricing, specifications, and any differentiating features for both types. Additionally, I would like to know about the warranty and available support services, as these are important factors in my decision-making process. Please also include lead times for delivery and any minimum order quantities. Your prompt response will help me in making a timely procurement decision. Thanks!
