Wiring Samsung F-series strips (diagram). Need help!

I had two strips (LT-FB24B) on one HLG-240H-48B driver which work great by the way.

Now I want to expand this build and add (to identical separate second driver) one more LT-FB24B and two LT-FB22B all wired in parallel. Can these two different strips be connected together on this driver without burning one out. Both strips have identical Vf = 46, but nominal current on them is different and it is 1120 mA for LT-FB22B and 2240 mA for LT-FB24B

Already using this setup below for 1.5 months with great success. Now due to absence of double row strips looking to replace one double row with two single row strips.

Well, after reading some more I realized my choice of driver is poor. Should have went with HLG-240H-C1750 which would have served better.

Actually, with differing strips having the same Vf as you describe, the c1750 would not work well. The small strips would run much brighter than the large strip.

So concensus is to match the strips/cobs on same driver so they have same current ratings? And then use CC driver that suites?

I never used constant voltage drivers before but everywhere online says they only work great under certain conditions

Post #5.
For strips of different currents but the same voltage, run them in parallel with a constant voltage driver. I have 1 ft and 2 ft. strips wired in parallel on a cv driver, works just fine.
