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.:mrgreen:

So true. Since April, my lights have been built, then disassembled and reconfigured twice now, with clear, incremental improvements both times. And I'm sure they'll be re-done again when I learn of, or think of, a different configuration that I want to try. No sweat. It's a satisfying feeling to DIY and end up with a product that is equal, or superior to, high end commercial product but at 30% of the cost.

I'm loving it and for my first time attempting something like this I'm pretty happy. I plan on doing more as I want to have enough light to fill the entire 10x10 space eventually and get rid of my hps completely.

So bump! Thinking cap times guys thinking big here maybe theoretical maybe not, filling a 10x10 space with these strips? Or more realistic maybe 8x8 so there's still room to move around. Ideally how would you go about this? Make multiple boards? Better options or mix it up with other lights maybe quantum boards? Budget around $1000-1500 ideally just for lights less would be better obviously lol.

Would want enough to cover a big size Rdwc setup maybe 12-24 pots.

Edit : forgot to add i already have 12 of the BXEB-L1120Z-35E4000-C-A3

And 2 x HLG-320H-C1050A

On 2 seperate boards of 6 strips each 300w each.

Ive done calculations on all sorts of sizes. I just got a $25 Lux meter, so now I sorta know what my 2x2 panels really have. My first builds, the strips are evenly spaced. Built before I was made aware it was definitely beneficial to stagger the spacing for even distribution. The most balanced of the panels is the 11x 560mm running on a MW ELG 240 C700.
I think we all understand, fine tuning on the LUX level relates to the strips' spacing, amperage driven, the K temperature value, and height from canopy. A man can completely dial each variable in, to get optimum coverage over any given space. I feel like, accomplishing coverage for any size canopy area is just a matter of building enough units (driver+emitter combos).
I had a 2x6 rack at one point, liking it better in 3 sections. Starting to wonder if even smaller units could be a benefit. SO many options...

Honestly, I would go with the 44" double row Samsungs F series. 288 diodes each - basically a quantum board in a 44 x 1.5 inch strip. Three strips mounted on 46" long, 4.850" profile Heatsink USA stock. Running on an HLG 320-48A for three hundred watts (give or take). Two lights for each 5x5 quadrant. Cost you about $1200 to build.

Nice will have a look into those.

Edit: any chance you got a link to arrow or digikey? Having a hard time finding them lol

You could also place some vertically around the plants as side lighting.

Yeah i figured I'd go with 3500k all round seems a good spectrum, will only be growing autos anyway. And yeah side lights might be a good idea, since if I get 10 of these strips I get the unit pricing discount works out cheaper then getting 8 lol.

3 per light, 2 for each side lights sounds like a good deal to me.

Um so getting into serious voltage and amps and wattage with all this I probably should be pretty careful yeah? Anything I need to worry about? How many amps will these be pulling i hope my power points can handle it.

Also can I run 3 of those double samsung strips on a
HLG-320H-C1050A

Since I already have those would save me some money, they also only run at around 1amp compared to the 6 of the 320H-48A

I would have used the F series strips too. But with the money I saved using EB's I bought another tent and 3 growmau5 pucks. Considering they do basically the exact same job with the exception of the F series being a little bit more efficient it's too hard to pass up on EB's. If I had no budget worries then I'd probably get F series though just to say I have the most expensive.
