SL-B8U7N90L1WW & HLG-480H-54B, strips wired in series or Parallel

Hello all,
So it has taken me a while to source all of my needed items to put together a fixture, on my fixed income. So I do know, and understand that there are better strips out there, to grow flower with. But this is what I can afford, and I have been told by someone on here, who I can no longer reach to ask questions of. So I am coming here to ask this here.

I have 12 strips of SL-B8U7N90L1WW . They will be assembled into a '6' bar fixture using the HLG-480H-54B, with a dimmer.

Q...What is the best way to wire them up? in Series or Parallel?

You probably should have figured out how you were going to wire them before buying the driver.

You are going to need 8 parallel circuits, each with 2 strips in series. So 16 strips?
Thats if they are going to ran at 18v 1150ma

There may be another way if you spend some time sorting it out. My math could be wrong as well, but that driver doesnt seem to be a great match.

Digikey says 48.2v. I'll check the data sheet a bit later.....

Parallel is the only way with that driver.
If it's not too late, I'd go with AB dimming or cc driver. Will post more later...

Hi, yes, thank you for the reminder. It is a constant Current driver. And the member on here who had helped me to choose the driver and the strips, had told me that would be very suitable for my needs.
I finally was able to order the aluminum heat sinking for the fixture yesterday, and that was the last item I needed to purchase for this lamp. I only need now 2 switch's to finish this off. Then I can assemble the whole thing , soon. And get back to an indoor grow.
Thank you all who had replied to this thread.

HLG-480H-54B is a 54v constant voltage driver. There isn't a Meanwell cc that matches well, unless you go with 14 strips.

Anyway, the HLG-480H-54 is 8.9 amps, 8.9A / 12 strips =.74A per strip. That's about half the rated current and a diodes forward voltage is less at lower current. I'd guess about 46v which would work with an HLG-480H-48 and that delivers 10 amps.... or about 12% more power.
46v x .74A = 34 watts/strip.
46v x .83A = 38 watts/strip.

Two switches? If you switch several strips off, the others could be over driven.

I thought I read this correct,. The HLG-480H-54B... Says it's a CC ,Driver.
2 switch's! The second switch controls the red strips, I have also .

That web page isn't a Meanwell document. ;-)
They list both of these as cc. :roll:
HLG-480H-54B, the 480 is wattage, 54 is voltage, B is dimming type.
HLG-480H-C1400B is constant current, 1400 milliamps.

So, the 12 stripe's I have will be under powered, with this driver I have? Correct?
I do have 3 other drivers, that will work, but this will complicate the build, add to the wiring, will not be dimmable, and contribute to more heat in the tent. I can not return the HLG Meanwell.

I wouldn't phrase it that way, I'd say the driver won't be used to it's full potential power. An ac watt meter is a good thing to have, as low a $13 on amazon. Or a multimeter.

I had 18 of those strips in a 2x6, 3x150W drivers, no heatsinks, wood frame made from gardening stakes. Not very efficient, had to have it like 6" away from the canopy but it did the job.
