Broken qb132's

Hey again guys, recieved a 4 pack of qb132's and some of the boards are damaged. The first board in line emits no light. Second and third board work fine. Fourth board has multiple unlit diodes. I purchased these from an ebay seller, not direct from hlg. These were not packed in the same manner as when you order them from hlg. May have been damaged in shipping. Is it safe to run these in this manner until I get the problem resolved? I have them on a hlg-240h-c1750. Sorry for the awful pic, my phone just wont get it right. Any insight is appreciated

Ouch. Are they on a CC or CV drivers if you dont know, whats it say on the front?

Was gonna mention that, but he said "until I get this resolved" so I figured he knew what he was doing. Just need to know if its parallel or series wired. Series, go for It. But parallel, definitely dont run them.
They are wired in series. Gonna run it on the porch for a couple hours just to be safe. Waiting to hear from the seller.

Well you completely avoided the second part of my question it's obviously a CV.
I avoided the second part of your question because its obviously a cc driver, as implied by the model number hlg-240h-c1750. It's not a hlg-240h-36. I may be incorrect about adjusting the voltage, but what else could be adjusted if the current is constant?Maybe I'm not understanding. Here's a pic

It constant current with current adjustment. Io is the current adjustment knob.

Constant current means the set current is maintained no matter what as long as you stay within the voltage range.

Are you sure they are running in series? If so, none of them should be working. If one dies, they all go out because the circuit is now open. Maybe you wired wrong? Can you draw a quick schematic of what you did?
