the 600h 48b driver has 2 outputs both with a positive and a negative therefore they are two positive and two negative. positive together and negative together with a wago 5 way
right?
Don't group your DIM leads coming from the driver with the OUTPUT leads coming from driver. Idk if you were suggesting this or not but I thought I'd say something.

Like what @Rocket Soul has said, you want ALL of your positive wires/leads from your boards going into 1 WAGO, and you want ALL of your negative wires/leads from your boards going into 1 WAGO. Then you take your driver OUTPUT positive lead and add it to the positive WAGO, and then you take your driver OUTPUT negative lead and add it to the negative WAGO. You do NOT add your driver Dim leads (neither positive or negative, none) to the WAGO. Only driver OUTPUT leads.

Each board gets 2 wires, 1 positive and 1 negative.

All board positives will be connected at 1 WAGO, all board negatives will be connected at another WAGO. Then you add your driver to the WAGOs, positive to positive, negative to negative. Clusters of "like" or same charge. No mixing charges within clusters. 4 boards + 1 driver = 5 positives & 5 negatives.

Any far red strips I can attach to the 560 board heatsink and use the existing 240 drivers, there's almost a couple of inches space (length wise) on both sides of the heatsink.

Was told by Meijiiu before my purchase that they were out of stock on the meanwells and it would not get here until the 10th. oh well.. well i got a notification yesterday that said it had just shipped from Hong Kong.

now dhl has it scheduled to get here tonight. shipping was free. incredible.

hopefully the product performs as advertised, which i believe it will. this is based on what i have read about them and emerald's pictures of the grow he has going on using Meijiu lights which looks really solid btw. cant wait to test it.

Got my light and assembled it no problem. Thanks chief.
Anyway I was getting worried because the thermometer I have in my tent started reading 80 to 84 to 88F. I was getting upset. Then, when I open my tent it's not even warm in there. Turns out the light was hitting the black on the thermometer/hydrometer and heating it up which was giving me bad readings.
The light is awesome. Im stoked. It's lit.. no pun intended. I'd have to see a real HLG 550 side by side but I'm sure it would be about the same. This light is bright! I can't believe it was only 4 bones shipped. Hopefully it lasts a few years or more.

Edit: decided to put the thermometer above the light and it was around 81F so a little warmer than i would like. not sure how it compares to the blurples i was using or the HLG 550 but its not as cool-running as i thought it would be. i thought it felt cooler when i stuck my hand in the tent, but the thermometer was telling me something else(88F at soil level, 84F at tent floor, 81F just above the light.) im just worried the new light is going to overwhelm my little plants but i can dim the light for now. i dont have a lot of money so this light was a big purchase for me and i just wanted it to be perfect in every way, which its not. it is however better than other lights for sure. bright as hell too. ill definitely update in a couple weeks

81-84F is were you want to be with led, due to no infra red spectrum. You should be fine. Overwhelming light: yes, it can happen. Generally with led try less before more, and keep the temps up around 81 for sufficient transpiration.

Can someone tell me how much Watt a Chinese 288 quantumboard ( LM 561c ) can handle without a heatsink?
I readed somewhere up to 50 Watts but just to be sure.

Thnx in advance and i wish you all a great and happy day!

No sweat my man. And ya, they can still give off a little heat. I use an exhaust that runs 24/7 once flower hits and in veg I keep the lights a bit higher. Ultimately you'll have to see what temps your plants thrive at. Somewhere in the 77° - 84° range while lights on. Many say to add ambient, and many seem to mitigate common "LED issues" with keeping RH high (50%-60%+). You'll have to find where your plants like it. I use a cheap IR temp gun ($10) to check LST (leaf surface temp) and I try to keep my temps (ambient & LST) under 82° while maintaining RH around 50%+/- (depending on stage of growth). That's just what I do. Good luck and...
