Looking for some educated opinions

Got a Mean Well 320H-36b driver. currently NO potentiometer hooked up to it.

Have 2 cobs, Citizen CLU048-1212 properly hooked up to their heatsink.

When wiring just one cob from the driver, brown driver lead to positive, negative to blue driver lead, the cob powers up brightly.

When wiring BOTH cobs in parallel, both cobs power up.

When trying to wire both cobs up in series, ie. Brown driver lead to positive cob 1, negative cob 1 to positive cob 2, negative cob 2 to blue lead on driver, NEITHER COB powers up.

According to the specs, it pushes out 8900 ma, so I'm guessing I can run 7-8 of these 36v cobs at ~1050ma safely in parallel with this current driver safely, correct?

Thank you,

The high voltage drivers work with the COBs wired in series. The high current drivers (HLG-320H and 600H) work with the COBs wired in parallel and those are good options if you want to run multiple COBs at high current.

Max current: 8.9A can power 36V COBs at the following approximate wattage (actual wattage varies slightly by particular chip -please note driver has a hard limit of 36V and cannot drive CXB3590 above 2.1A. CXB3070 above 1.6A, CLU048-1212 above 1.2A, or Vero29-D above 1.3A):
5@1.78A (~64W ea) (CXB3590)
6@1.48A (~52W ea) (CXB 3590, CXB3070)
8@1.11A (~40W ea) (CXB 3590, CXB3070, CLU048-1212, Vero29-D)
10@0.89A (~30W ea) (CXB 3590, CXB3070, CLU048-1212, Vero29-D)

Thank you much for this info and confirming that 8 1212s can be run at 1050ma. That will get me 320 watts on that driver, which is what I'm looking for.

THANK you,
