LED noob, need help!

I like to wire in series. I like using CC drivers. I like to keep the Voltage per fixture on the lower side of 200. I also like my lights for larger areas in pieces, so they have more flexibility long term.
This particular combination meets all those requirements.
Glad I could help, others did it for me when I was first learning this stuff a few years back.

Forsure, I’ll keep this in mind.

I saw your plan was for a 4x8 area, if I was to do a 4x6 area would you just cut the order down by 1/4 or stick with 4drivers and 36strips?

Also I noticed the Bridglelux strips are 560mm(22”), would the dimensions of the frame be 22”x6’ and that would have a 4x6 footprint? Learning as I go

I would probably make 3 sections of 9 strips, about 3 feet in length each, then hang them side by side. So you'd end up with what amounts to, 9 rows of 6 foot strips....
There's a fine line when spreading out the strips, if the gaps get too big the intensity falls off fast.

EDIT: It's going to be different.

The longer I look at this, the less I like it.
Might have to take it up a notch.
Is this 4x6 an open space, or Tent?

I think this current plan is going to come up short on intensity.
This is a common situation when dealing with only 22" strips. Gets tricky matching drivers to spaces. Best to miss on the high side.

Here's where I f'd up, I knew something was wrong....
4 drivers with 9 strips each for a 4x6,
NOT a 4x8.....I knew something was going off kilter.

It’s in a 7x7 room, I have a 1000w HPS in there now with an AC thats costing a fortune, and I’m getting terrible yields, that’s why I’m liking what I see with these LEDs. I’m trying not to spend an arm and a leg if it’s possible too.

So my frame would end up being around 22”x6’ with 4 groups of 9 strips in this case? Or am I misunderstanding

That's 20 watts a square foot. Seems rather low with your 1000 w HID unless your not using the whole tent and have the plants pushed off to the side with the light above it. Also a XL hood might help you out. I hear you on AC and cooling HID lights, been there.

No, there's a way to create a 4' wide, by 6' long unit, using 22" strips.
What you'd have to do, is make 3 "ladder" shaped frames, each holding 12 strips, 4
feet long.
These sections, could be hung 3 wide, to get the 6 feet lenght covered.
The wiring would incorporate 3 strips on each section, for each driver. Strips #1-3 on sections 1-3, would be one circuit of 9 strips.
Strips 4-6, 7-9, 10-12 the same way.
Is this making sense?
It's the only way I can imagine getting a 4x6 photon quilt, with these particular parts.

Maybe something is up with your exhaust if your temp is that high with 20wsqft?

Ya i have to agree there. Perhaps a upgraded bigger exhaust fan and xl hood might be your answer. But if your using the whole tent thats really a small amount of light for that space. 7x7 is a rather large space. Someone correct me if I am wrong but isn't it beneficial to have 65w per sqr ft with HID?

Yup, making perfect sense. I’m 95% sure this will be the route I go.

Oh my ventilation is fucked so I’m sure thats most of the problem.

My yields are less than an ounce per plant, so I’m guessing I have some work or buying to do, but I only have a few flowering right now and theyre right under the light
