I received the current limiters in today and they work as advertised. For 7 LEDs in a string and 11 strings per board, the board pulled a total 220ma. The limiting kicked in at about 27.7V.

I will still need to build a boost regulator to kick the 12 volts up to about 28V, though I can run it on my bench power supply in the interim.
