He specifically said a couple pages back, in this post that he was running them in parallel:
yup my bad, already noted in a follow up post.
But he has the boards connected + to +. Did you not see that pic? That's where this debate began. It's in the post I linked to above.I think I see the confusion @Frank Nitty. They are wired in series! None of us paid enough attention to the photos you posted and conclusions were jumped to bc u mixed up the terminology. All is well you have them wired the right way.
The green wires connect the boards together, and you have a single red white pos/neg going back to the driver.
If it was running in parallel, each board would have its own white and red wire going to the driver directly, and no green wires connecting boards.
I stick with my original comment that those molex connectors are shitty and ive broken 2 or 3 myself.
So everyone made some mistakes, can we all roll some fat spliffs now and be friends again pls
Sorry, I'm still catching up with all posts of the thread.
I respect that...
I think you will need drivers that end with "-54a/b", if going for constant voltage drivers / parallel build.
What driver are you using?
I understand those are recommended. Already have the 48v and want to know if they will light the boards properly/efficiently.
The qb288 needs 54v. So a constant voltage driver ending with 48v won't do. You'd need an hlg-320h-54a/b, for example.
hlg-320-48ab puts out 50v max. So i'm asking.
I would certainly give it a try. It will either work, although not a bright as it could, or it won't. Since the voltage is under the recommended amount, it won't wreck anything if it doesn't work.
I like CMH mixed with LED best, but right now I'm just running the LED's.
Ya, I'd like to know too now.
Oh, ok. Cool. I don't know, can't help ya there.
