I have 12 HLG QB 288 rpecs to make 2 fixtures. 3 of the 12 boards are clearly a earlier version with all the white diodes the same kelvin. The other 9 boards have a mix of white diodes. Is that going to be problem in parallel? I am doing 6 boards per driver so keeping the 3 boards on their own driver is not an option.
Using different HLG QB288 rpecs on same parallel circuit?

You need to test each boards Vf and see how close or not close they all are.I have 12 HLG QB 288 rpecs to make 2 fixtures. 3 of the 12 boards are clearly a earlier version with all the white diodes the same kelvin.

Even for the boards that are "the same" it's still good to pair as close as possible Vf's together if going to be driving in parallel.
HLG is exchanging the 3 boards. I understand you should test Vf for each board, i dont have any idea how to do that. I will have to settle for the same diodes on each board. I have been using strip lights of different kelvin in parallel for 4 or 5 yrs with no problem. Cant imagine testing each strip for Vf in a strip build. Unless its a lot easier to test than i am guessing.
