Help with strip build/partlist

I was thinking about picking up 16-20 of these and running them in a 4x4 tent, I'm not really too familiar with bridgelux, but it seems like a good deal. I just ideally want to run them without heatsinks on an angled aluminum frame.

I'd like to use a 600w or two 320w meanwell or inventronics drivers.

Really any advice would be very helpful.

Bridgelux EB Gen2 560mm x15- per each HLG-320H-20A = heatsinkless photon quilt.
Bring each strip in around 1000ma(ish)
I've been running Gen1 EBs at these currents for a couple years, some completely bare on wood framing.
There's a few ways to go about it, but even up to 1400ma per strip on aluminum U Chanel, or angle, is plenty for EBs.

Updated the link at the top (me= )

But I like the 1120 mm ones personally.

I kinda thought you might be referring to 1120s considering your 16-20 strip count.

I couldn't be more satisfied with the results from all my EB builds.

How many of those would you suggest I buy if I wanted to run them in the 500-700 ma range?

I'm keen to start playing with those. I started up a Growlight company that focuses only on strip builds for now for my local market, but ironically I think the value lies in the frames I produce, as I can put almost any strip on them. Just this week I walked into a batch of aluminium stock again which hit my brain with a jackpot of potential ways to use them. I think eventually I will sell the frames and strips and drivers separately.

Today I'm building jigs for the metalwork, to aid in repeatability of each build. It is quite a work of art.

The goal is to make sure that those who want LED get proper gear at reasonably affordable rates.
People are still buying mars and blurples here

1120mm EB Gen2 are 39V strips.
If you used an HLG-600H-42A you have 14.3A available. Each 320H-42A has 7.65A to use.
Take the 14.3A(or the 7.65) and divide by the number of strips, you'll have a rough idea of what each strip is getting, in a parallel circuit.
24 strips on the 600, gets you just below 600ma(ish).

When you run a blanket of photons like that I assume you can get a bit closer than say boards?
What distance do you like in flower from canopy?

It's all a balancing act between strip spacing, frame size, and drive current.
I use a Dr. Meter brand LUX device, to target 40K(ish) LUX. I've had some blaster panels at 1400ma that generated that level at 24". I've also had softer, wider, panels, that had to be at 4" to hit those numbers. For a baseline build, a 2x2 panel, with 8-9 560mm EBs, at 1050ma with a 185 MW, will get 40K at around 8".

I have seen another grower I built lights for, have tops nearly touching the diodes at 700ma.
I also experience satisfactory flowering on lower branches that only get 15-20K LUX ...."Dr. Meter LUX" that is.... whatever that factors into, vs a high end light sensor. He heee

Flowering at 5" with 850ma, 30w/ft. I think it's around 45,000 lux on the cheap meter.

With the current prices on Gen2 EBs, we're talking about that elusive, sub $1 per watt zone, all in, with hardware!!!
Going to have to find a way to need more lights.

Yeah i have too many lights already but im still itching to pull the trigger and wondering who can i build a light for.

If you factor in the LRS power supplies and are happy running them im sure we can hit way lower than $/w
I think thats how nfhiggs was rocking it.

I worked out that with cutters cree J series strips and a LRS 350 i could put together 350w build for a 1mx1m tent for less than £100

With this sale on EB strips it has to be cheaper.

I imagine you get good prices on aluminium where you are?

Yes, I have a good source of awesome profiles...
I have a strong dislike for plastic crap like Fluence is pushing.
the only plastic part on my fixture is the waterproof inline connector on the AC side of the driver... I just haven't found a 3 pole one in chrome yet.

The idea behind the lights is that you will be able to upgrade to other strips down the line but keep the awesome, light, strong,good airflowing, wide frame... the small fixture is 58x60cm that is basically a 2'x2' light frame, it will light plants in a small tent-like a fucking blanket from way above. I am not a fan of the keep in low and close school unless you are into scrogs. If you do any kind of pheno hunting you want your lights hung as far the fuck away as you can manage, cause the height difference will fuck you over if you have a shallow field of usable light.
