I'm pretty sure you could talk them into making anything as long as you have a good enough reasoning for it n they prolly follow suit. Just get the Alibaba app and you can chat with them directly. These are mine... Just got em

Wait, what!?
So these meiju boards with the 561's the small ones that 'run 120w' with a heatsink will do only 30w without a heatsink? I was seting up a light at 4 boards per HLG-240 making it 60 watts per board without heatsink as meiju said they would be fine up to 60w. I have to go back to the drawing board?

You'd need to check back of board temps with an ir thermometer while slowly turning up the driver.
I'm not sure which board you are referring to. Is it a 288 diode 12" x 8" board ?
A QB 288 MAY require heatsink at 50+ watts
A fan blowing on back of boards will lower their temps nicely

I was talking about the folite 304 led boards with 1oz copper with 286*174*1.6mm dimensions or the folux 288 on the same board size and thickness I believe. Which of these boards is the better board anyway? I am assuming the 288's thanks to lower voltage having more PSU options making them more flexible.
They sell them as 120w boards including a heatsink and 120w PSU (or a double with a HLG240 or quad with 480).
I figured mounted in some alu L frames I could run them at half power, 4 boards on a HLG240. Anyone with first hand experience? Of course I can always run fans on them and the area they will be in is ventilated, plus these things can take more heat than we allow them to get to be on the safe side. I mean its great to have them running at 35c but they are still just fine at 55c as far as I know.
Am I still being realistic or should I be looking at the LM301 boards for better thermals (is this even true? Its in the QB sales pitch), looking at mounting on 4mm alu plate instead of L frames, or go for 6 boards per HLG240. (or even go for fotop 800 instead, my least preferred option)
I am trying to be energy and heat efficient, while also being price efficient and at all times keeping safety in mind.
As for safety, if one of my 4 boards for whatever reason craps out, does that bring the other 3 boards up to 80 watts each, making 6 boards a safer option or is this safety concern negligible?
Edit: I'll likely go the HLG heatsink route (4mm 660*490 alu for about 20 eur excl VAT each) and run them 60w but am still curious about real world results without heatsink. Hope Rita is working Sunday

With that much wattage, 480+320+320? Thats an oven of light. For a 4x4 id go for a hlg 480 and 3 fotop. When building the frame i would do it slightly bigger than the fotops so i i cou but some kind of strip on the short end side in case i wanted more light or spread. Or maybe some side light but like really soft, 20w per 312.

Hey Rocket, what's your opinion on supplemental lighting with the fotops? Should I get some deep reds and UV in there?

Its optional and will benefit you. Get the right UV spectrum though.

I dont know cause i havent tried it yet. But hoping to do for the next build, mainky 660nm.
90 cri spectrum would be interesting aswell.
If i was to add one thing to 3000k/80cri it would be far red, end of day treatment and a bit during the lights on aswell.
Edit: and i would love to try some real infrared.

i would do a whole run with just red just to see if ihad a panel..i saw a mostly red grow where yeh the leaves fried off but the buds were colourful large and more resinous..

Update on the R2T boards.
I put the 2 x boards on a 900mm x 146mm finned heatsink wired in parallel and attached a
Meanwell hlg 185h 48A driver.
These were to replace a QB at 60 watts and a Growgreen board at 70 watts.
Total of 130 watts of 672 genuine lmc501 diodes.
So after running the r2t 2 board fixture full blast for 1 1/2 hrs to warm it up i set the hlg 185 driver to 130 watts, the same watts I removed.
1152 diodes and it gives me better coverage.
The light slots in on the left, along the length of the Fotop boards.
The par readings I took looked great.
10" away from plants
The next batch going under them will tell the tale better, these only have another couple of weeks to go.

Pity you can't do a grow with just the r2t boards in a space of their own, would certainly show what they are capable of. Again thanks for taking the time to test and show, much appreciated by myself and im sure others. Either way they work and the plants don't care if they are coca cola branded.
Your plants are looking healthy as per usual, with a nice crop of juicy buds.
Can I ask did you get your apogee local or import? asking as I could do with getting hold of one to setup my cab once and for all, well for another year lol.

I built me a wee little veg/seedling/cloning box with Chinese Sun boards from Mufue technology. Each board hosts 96 Samsung LM561C S6 chips wired 8S12P which makes 24V nominal Vf. I'm running those at roughly 25W each in a 600x800x800m box off a Meanwell HLG-120H-C1050B. Got 4x4000K and 2x2700K in there
My next project is a 1.5x1.5m flower room with this Sun boards, 26 of them and 2 HLG-320H-C1050B drivers. Should be a perfect match for maximum efficiency on the driver and the LED side.
I'm also upgrading my existing light with a 320 Sun board running at roughly 100W

The apogee was bought from US... was the cheapest option

What you you guys recommended for a 3x10 space?

piggybacking these temperature posts with a question for you Moflow;
been working up to 300-305ish watts on the fotop 800 board in the 2x4 grow (with a heatsink) and I am looking at 50-55 degrees (c) on the hottest side of the board (furthest away from the closest fan blowing on it).
Any reason why I shouldn't be comfortable with those temperatures, as long as it doesn't affect the overall tent temperature negatively?
What temperature wouldn't you be comfortable running these at?

50- 55 , That's sweet.
Back of a strip temp of lm301b on de tech
If they're happy with those temps then I am too....

How high do you have tonhang it for even coverage and no burning in the centre? 12" @200w was what we found fine and curious on your setup
