Mini Magnetic Hooks, Small But Strong Magnets for Hanging Lights Jewelry Ornaments Keys, Tiny Magnetic Hooks for Refrigerator Locker Metal Door Cabinet, 8Lbs Holding Capacity Black 12PCS

I used small fans from amazon that come with USB connectors and can be daisy chained, they have male and female connectors. I can send you pics when I turn my lights on (if I remember lol) basically they have both a usb to plug in to receive power, and a usb you can plug in to connect them to each other. I checked my amazon account but it looks like my ex purchased them. I used a mix of magnets and large suction cups to hang them. I purchased metal plates that stick to the glass (similar to the ones that came with the lights) and really strong mini magnets These are the magnets
