I picked up an addressable 12V 21M (69ft) 20LED outdoor for $12 on Amazon. The included controller is, as you would expect, loaded with crap software. I don’t have a Govee or Atom set ($50 - $100) to see how the brightness compares. But they aren’t real bright, more decoration than actually light up your patio.
It was fairly easy to convert over to using with WLED. The lights use the WS281x protocol. The controller and connections are all waterproof. There wasn’t anything salvageable in the controller. The board inside was covered in some kind of clear stuff, softer than hot glue or silicone. Just cut off the wires close to the board and use them to make your new controller waterproof. The output pins / wires are not labelled. The outermost wire is 12v, center data, and innermost is ground. Mark the 12v line when you cut it because it would be easy to get them confused with the round adapter.
