Can you do me a quick idiots guide to the doubles please, mine have arrived and I don't want to fuck them up.@Gazooo entire batch has same Voltage bin. No need to match Board Vf if using same Spectrum boards from same batch.
If you want to calculate VF of each board, each board at a time. or you can hook them all up too. eye protection.
always wire the LED and then power on. connecting Board/LED/COB to a powered ON Constant current driver can cause damage Board/LED/COB
