Right at 18"
Any closer and they start cooking. Haha Took some damage dialing the distance in, but now it's awesome.

Id say 250-300 wood get u nice results.. Lighting is key to final product being good but grow knowledge is just as important.. I had qb132's tho. But the 250-300 answer i gave was for flowering. In veg u get away with half that amount. Save power for flowering, less wear on ur equipment, and turned down u can put the lights right on top of plants in veg. Even in flower i had mine bout 6 inches away from tops but need air flow across canopy and on boards. That helpd me. I have no experience with qb 288's tho so ur height might b different. But hope it helps

Yep 300 watts per 2x4 space would do nicely ( even better with 320 driver / more flexibility).
Think blocks of two when upscaling ( bigger tent / space ) .... and with proper overlap spacing .

AlphaSoresRex 200w / 1/2 lit.
Shout out to Cammi fir hooking me up with 3 & taking the time to get them going. Plants are really feeling this spectrum. Plants that i cant grow under white are eating it up.

You should take reading on glass on and off.
Here are mine. I have them on Mrs. Perm's stuff.
Like hybrid said these are called Alphas. They were 400w greenhouse prototypes. Half of the boards are unhooked, so they run at 200w now. Nothing wrong with the other half though. Same spectrum, they are all the same spectrum except for OHD's one off lettuce rig.
Here is glass on and off. I even cleaned the glass when I hung them up a few days ago.
I honestly thought these lights were blurple bullshit a few months ago, but I figured I'd try it out. I would still believe this is all bullshit if I hadn't been seeing impressive results under these lights for myself. I can't wait to see how flower goes on our plants. That's going to be the test.

Blurple is still the most productive spectrum and can even beat 3k results.
That's below is a spectrum used by an Osram company called SanLight but they have switched and use supplemented white diodes with red and deep and far red to create it.
So if you use quality diodes with the same efficiency you can easily get the same results watt for watt. Its not enough to create just a good spectrum it also has to be efficient like for instance the Amare SB-8. The solar spec C spectrum should have a similar looking spectrum with all its red, deep and far red.
Its just cheaper to use white diodes and only a few monochronatics. Unitfarm and a few other suppliers have created good and efficient blurple fixtures but they were too expensive compared to other lights.
Its like with the HGL's, 450 bucks for what 180w? Thats simply too expensive if you need 4 of them to cover a 4x 4' area.
They only need to use better diodes and lower the price per watt and they would have a killer setup!

They did.
This grow is about the x3 model. It has since been discontinued, as in you can't get them now. They aren't keeping them floating along to make money here and there off of random sales. The replacement for this light is the XB140 on sale for $239. Same spectrum, more efficient and up to date. Four in a 4x4 would be $956.

Theres absolutely no proof of the new ones being any more efficient than the old ones since Cammie has never put her lights thru real sphere testing which is standard in the growlight industry.
Just sayin...
Why not run all the led a half the current? Seems like a waste to have a bunch of led turned off if you can take a ppfd of the fixture with all the boards vs half the boards at the same wattage it would be interesting to see what twice as many diodes at the same power does to output does to ppfd

That's a great idea. I'll see if I can.

I checked it out. Can I lower the wattage on a PCB?

you can change the driver probably to do this.
Or may try to do a small solder job and put 2 board in parallel, current should divide (if the boards are the same).
Like this, as a example, please meassure before yourself, haha.

Yeah, you dont know?

Shes claiming they'll be up to 2.8 ooohmols/J electrical efficiency using top-bin Epi-Somethings (stars/leds/ect..) ran soft, using twice the amount of diodes per sq' as HLG which was their base model to work off. She took anything & everything growers had concerns about regarding the HLG QB desighns & tweaked it to work with less density issues. Which in turn should allow for closer proximity growing.
Priced decent if they indeed do outyield Premium White fixtures.
Monochromatic diodes have always costed a chunk more then mid-powered whites, so i agree with the use of top-bin Epi's in order to keep costs where they are, (under $2 a watt). You're right, UnitFarm went top-line everything, making them to small to balance manufacturing fees probably. But we know what their spectrum generally produces if its he basic 450 + 660 8 think it is that so many burples chose to use.
Also the QB desighn is the absolute least expensive to create, package & ship. Also the fastest to produce. To me that means if HLG didnt have the price set so high (used as industry sandard now) then other following QB distributors could & prob would offer these at closer to $1.05 a watt. Or we could just put the high cost on NextLight for being the first to distribute the QB style.
Originally designed for the sole purpose of drop ceiling replacement upgrade lighting. I've seen them dated back to early "16" in a KFC remodel job.
Ill be putting x2 or x3 XB-300'S against the Bar-8. Veg - Flower next run.
Just gotta get another Bar'8 & the XB's first. The hard part.

Wow, thanks!
I'm going to start another thread for this little project so we don't clutter this one all up any more than I have, sorry.
Depends on the driver they probably don't use adjustable drivers you could wire the boards in parallel
