美国采购需求：照明，泳池灯

I'm looking to purchase both a 6" and a 10" wifi-controlled pool light for an upcoming project. I noticed that the 10" model seems to be out of stock—could you please confirm this? If it's not available, I'd like to know when you expect it to be back in stock. Additionally, I'm curious about the functionality of the lights. Can they be controlled individually, or are they designed to work only as a single unit? This would help me understand how to properly integrate them into my setup. Thanks!
