Using Pixel strips on a real tree

[1pet2_9]

I have a strip failure in the middle of a PEX arch, on a WS2815 strip. It's supposed to be a waterproof strip. My 5-meter arch became a 3-meter arch. I would love to know why the pixel went out in the middle, but I don't. My most likely cause: sometimes pixels just fail.

Sometimes pixels do fail. Sometimes there is vibrations that break internal solder joints. At worst case a trace can be broken for nothing more than being moved and shaken, even in the slightest.
