Accidentally ordered a 72v cxb3590 cob

Soooooo I was shopping high (big mistake, never again) and I bought 2 cobs, 1 is 36v, the other is 72v.
The drivers i got are HLG-60H-36A so its not gonna run it but LUCKILY i've got a spare HLG-60H-36.

I'm guessing fusing these two drivers (HLG-60H-36A & HLG-60H-36) would make it possible to run a single 72V cob.

The difference between the 36A and the 36 is that the first has a screw you can turn to tune up/down the wattage output (30W being the lowest, 60W the highest).
If I use them together, would I still be able to tune down the wattage by turning the screw on the 36A?


And also, even if the 36A is dimmable, does mean my only range would be 90W-120W using this combo? Is there any way to tune it down? I only need 60W max :(

Series drivers are something none of us are gonna give you the go ahead on. In theory it should work but I'd never do it. I'd return the 72 an get the right 36V.

Sadly returning the 72v is impossible. I live outside of the US. Returning the cob, and then paying for new shipping + taxes will add up to additional $78.

Is it that dangerous to combine the two drivers?

Maybe run them separately, never want to mix different voltage on the same supply, just asking for trouble. Technically it could be done, but would be much easier running the same voltage lights on the same supply. Electricity is a fickle bitch sometimes.
