You should be good, and series would be preferred. How's your wiring? Does it look like this:

Yeah double and triple checked to make sure the series wiring was correct. I have a extra hlg 185h 48a would this one work? Wonder if it's the driver.

That's is the right driver, recheck your wiring.

That one will only work in parallel.
Thanks for your help it worked with the hlg 185. Guess arrow sent me a bad driver

So i think im finished but bit concerned about the amount of flex. I have another 6 strips to use and build so any suggestions are welcome on how to improve this. Not sure if I just scrap this one aswell since it's flexing so much but at its current height it's 35inches from the top of the pot and does 20k lumens, at 18 inch its 30k. Anyway I can convert these lumens into something usable like ppfd etc? The flex doesn't seem to make much difference in that way but I still think it would be better if all are pointed down instead of these outer ones pointing sideways also. Been a bit of a clusterfuck trying to do this on the cheap since I don't have any tools but I now have a decent drill i can use so might just go with some thicker aluminium for less flex. Thoughts?

Maybe it's jut my tired, old eyes, but I can't tell what I'm looking at in your photos. Perhaps if you describe your materials and how it's put together (or did you do that earlier?). Is it just that the end cross-members are too thin?
edit: Ah, I looked back and found your materials. I think if you just attach your aluminum sheet to a rectangular frame of 1/8 x 1 x 1 angle aluminum of equal dimensions it would stiffen it up significantly in all directions.

Can you use 2 pieces of alu angle to brace it. I cant see that you have anything perpendicular to the strips?

Either move your driver to a remote spot, or use a couple pieces of angle to stiffen it.

You could just move the hangers in a couple inches on each side toward the center and it will take the bend out of it.

Got my 2nd light up, will fix the other one at some point lol. How do I go about working out watts per square metre/foot? I have a lux app on my phone that says I'm getting 30k lux across the conopy with lights at around 80cm from tops of the pots. Closet is 9ft x 2f. Anyone know how i can work it out lol each board is 6 strips, 300w each so 600w total.

600W / (2*9)sqft = 33W/sqft
Nice veg numbers. Just 1 more light to have optimal flowering specs.

I would like to say a couple a things...first 33w a sq/ft will get you piles a smoke. Just lower your light and your lux/par will go up.
I run my EB strips about 4" apart and about 4" from the canopy...then I just dim them down as needed. If you run them as high from the canopy as there is space between them, you will get a very even blanket of photons across the canopy.
I run about 10k lux for seedlings and clones. About 20k lux to veg, and about 50k lux to flower. (My experience...your results may vary)
Secondly, things like, "Holy crap! I put my power supply in the middle of my light and it's all bowed out!" That is normal diy to have to redo things after trial and error...often several times. Don't be too hard on yourself.

Your space is also narrow. Make your walls as reflective as possible even if it means grabbing some panda film to line them with. 600w in that space will be fine for flowering, especially if you run a scrog.
