The Chinese Quantum Board Knock Off Builds

Having trouble finding this. Do you happen to have a link? And a link to the Meijiu with Osrams too, if it's not too much to ask? I honestly couldn't find either.

As for Meijiu. They have a similar 240watt for $130. UV/IR, etc. Similar to Bava. Not as many options. 80cri instead of 90cri, etc.

I dealt with Carrie Wu for the Majo's.

Nice light. Don't have one but a sweet deal for a 2 x 4.

I got a few of these built for a friend this week. Each fixture is 5x3 large, with 4 fotops lm561c 3000k 80cri, 3200 diodes each. As is the diodes are softly run, .15w per diode, slightly under nominal.
We did 4 in total, 2 with cutter redstrips (660+730) and some IR (850nm). The other 2 will be kited with more cutter reds and some china 630nm strips when they arrive. IMG_20190916_180657_201.jpg

Nice.
You say some ir 850nm, are they on their own strip or attached to the cutter strips with the 660nm + 730nm? As in 660nm + 730nm + 850nm strip?
How much ir?
Do you have central support on the FOTOP boards?
I was thinking that maybe the bend in the boards might cause stress internally, anyhoo, I ran a strengthener down the centre of mine. To be sure, to be sure....:bigjoint:
 
No central support on the fotops but the frame is secureed by 3 u-channels. Built tthe sides of t-channel: better support and added value: i can put them down on horizontal surface without leds touching the floor.

Strips are cutters, 10x 660 with 2x 730nm, i think they are cree xpqs? They sit in series with 2x 1foot strips, custom from cutter, with a total of 6x 3w 850s. You can hardly feel any heat from them. The 6 strings are powered by a hlg185 -48A for about 700mA each.

I was thinking of 850nm for heat in my 14°C - 22°C grows lol
We're the Cutter strips worth it after customs and duty to Europe?
 
thats a big one Rocket !
Good luck with the build.

For my next build i will try these eb3 strips, looks they will fit my setup.
Still like the Samsung LED boards, while thinking somehow theyre not made to last long (no matter whoever manufacture it).
Do anybody softmount them or do all screw them direct?
Asking cause i still want to figure out what is happening, or how to avoid the mechanical stress.
 
does anyone have any of these king brite 320W quantum board UV IR RED 660nm diodes, hlg lm301h grow lights and finished any grows with them?any opinions?i have used kingbrite when i built all of my cxb3590 lights.i need 6 lights and i grow vertical so i like the 3 board lights for my style of grow.
 
probably to new to have any completed grow.
They should be ok, maybe seperate the UV to be safe. ir maybe too if not on a seprate channel.

Red is usually the 660nm
IR is usually 730nm
UV is usually 380nm ish and UVA.

All can be run all the time harmlessly I’ve found on Meijiu with these.

Your mileage may vary.

Sweet Seeds Red Mandarine Fast F1 - 3 weeks into flip under the new Meijiu Majo.

Not topped. Just pulled the main to the left.

One more week under the new lights. Still dialing in.
Going to add 4 more bars to fill out the top gaps.
I want nothing but even exposure.

It’s like working with radiation.... except I don’t want a focused point source, but rather an even and consistent saturation of PPFD (mR lol) across the leaf surface.
