I've tried a bunch of different methods to have some tube looking lights in the yard. I found some simple white wire loom looks great and is easy to keep straight. It has an awesome look at night!
I'm using addressable pixels on a 12v power supply connected to the LEDeez board from WantMoore.tech running WLED. Super simple to setup and wire up.
