Get 5-way wagos. 2 outputs and 3 boards in the same wago.

Yeah, the 2 outputs are mainly because of the current flow. An HLG-600H-24 for instance has 25amps the H-12 even 40amps. It's better to split it on 2 circuits to prevent the wires from getting too hot. It would work with only one set of wires but it's better to use them both.

Got my 800 board and 320 driver today, got it set it up a few hours ago.

In a 2x4 tent, had seedlings going a week longer than I would have liked under weak lighting. Will be interesting to see how they bounce back :-)

Currently running it at ~130ish wall-watts and about 22" over the pots...

Greetings, I am on my first grow and also got one of these 800 boards from Meijulighting or something similar to that spelling. . . . . anyway hows it goin? excited to get my hands on mine. right now I have 8 plants in a 2x4 ( I know its a lot) all in 1.75 gal pots. they're one month old tomorrow ! all under2x 600watt amazon phlizon led panels so the upgrade will hopefully help

It will help immensely. What was cost and what did you buy exactly?

They are most likely not lm561c but rather lm561b+ as on your closeup of one led the dot appears very clearly and from what ive read/seen it is specific to the b+.. that being said its a +/- 10% effiency from the C.. i had seen those board ended up buying the 304 boards.. very satisfied and im sure you will too.. its good to know that they run cool even at max power without heatsink.. im looking to build another tent soon i may consider those big boards unless I feel like I can do a strips build.. but one thing at a time! Lol thanks for sharing man they look great

How much you paid for shipping?

Thanks, Amazon for everything prime

Rita at Meijiu.

Like I said. I'm a noob to wiring these panels and I am asking because she said this would affect the lumen output.. ?

I know. How would you use a hlg-600 to power 3 boards?

Thats only two parallel outputs on an HLG-600H-(12-54A or B) to splitt the current on two separated circuits(HLG-600H-12 has 40amps). You can use one board on one and 2 boards on the other port only make sure the boards are connected in parallel(parallel + parallel stays parallel).
You can also use only one set of wires for all three boards(in parallel) but in this case cap the open wire ends of the 2nd set of wires at least with Wago's to avoid a short.

(If you look at the block diagram you can see electical its still only one current source, only two sets of wires)

Cap the other output lead as in twist the + & - together and cap, not cap each one individually, right?

What would happen if you were to use 3port wagos and connect both negs and pos to their each own wago and use the third spot for a wire coming off to use as both lines joined together? :D

With both lines jointed together it would lit up.. Same as if you connect two drivers in parallel...

Its just one driver and one current source.
Simply imagine a driver with two DC connections; + and - .
And now imagine there are two wires soldered on each + and - connection.
If you connect a board to one of the outputs and close this circuit it will already lit up.
You can not twist the unused wire ends together and when you do it you will cause a short on the 2nd line! The boards goes off because all current would flow thru the circuit withoud board(because there is no resistance) and the driver will also switch off immediatly because of its short circuit protection.
So you can use only one side but you can not connect the open wire ends. Instead you need to protect this wire ends from getting contact and for this wagos or any other insulated connectors are enough.
