I've identified the LEDs as SPBWH1332S1BVC1BIB and have them on order. From what I can find online, they are 3v 350ma. The diodes are marked CJ which has 24V on the board next to it. The other is marked CB and has 12V on the board next to it.
I tried something like the third image except I don't have a DC power supply. Instead, I used my variac, a bridge rectifier with a filter circuit, and 2 multimeters. Works OK for low power applications. My results below are the lowest voltages where the 2 meters were no longer the same. The Strips have 8 LEDs each. Do these values seem correct?
CJ = 31.1v
CB = 15.2v
