Okay so I ordered these which are almost exactly like the ones linked above. The power/controller, the wire, the led size/shape/construction all look identical except for the shape of the junction boxes (with hooks) for each drop.
Anyway - the million dollar question - how are they wired and what protocol do they use. I’m happy to report they are all wires in series with a “return wire” running from the end of each drop back up to the top to continue onto the next drop. Despite 4 wires from the USB, one is not connected. So it is 3-wire, WS2812-like protocol with GRB order.
Can you simply chop off the controller and run it direct from a pixelblaze - yes you can.
