Hook the string up to a 5v controller to test. A 12v string won't be harmed at 5v.

Found most of a string of pixels kind of buried in a box. The pcb itself just has ws2811 printed on it, with a + and - to confirm polarity and an arrow pointing to the green data wire to indicate direction. Other than that, I cannot see any indication whether this is 5v or 12v as I've had both over the years, and it looks like pretty much any bullet to my eyes

If you look real close at the circuit board it usually has a 12 or 5 printed on the +'ive pin. I use my phone and zoom in as much as possible with the LED light on.
