Prebuild would be much better

I saw that too; is $118 delivered w/driver (Led Grow Light Quantum board LM301B SK 288 V3 LED Board (3500K: 288pcs Samsung LM301B SK Bin ) and a Meanwell) a good price? Or just a competitive price?
Also how much square feet does that cover?

That does seem like a good price if it includes the driver
I think PGR said that 1 288 diode board was good for a 2X2

3500K has been hyped based on assumption.
Get 3000K or even 2700K if you can find it, you'll always want to trade a day or two extra veg for bigger and more potent flowers.
Beware of ebay and alibaba, you can't be sure that they send the diodes they say.
Check out Atreum, they have some sweet board + heatsink combo deals.

Agree with the comment on color
I have found 3000K to be the sweet spot for all around growing
And I would never go beyond that, I actually would like 2700K
Because it's all about the flower
When I got my second Quantum fixture, I wanted 2700K
Because I already had one at 3000K, I thought it would be a great match
Alas, I couldn't get that color temp from my supplier, so I went with another 3000K
3000K is good for veg and more than ok for flower
2700K is wicked for flower

Interesting you both say this, i think ill try 12x 2700k when they are in stock. They would be in a 4x8 tent with 3 plants being under 3500k and the opposite side 3 plants under 2700k, we would then see a perfect comparison as they will all be in a 6x 5g RDWC all same strain, same clones

This is why I'm so spectical thing it's safer sticking to shops sort of say rather than eBay as like people say you don't always get what you buy
One bit of advice on the Meanwell drivers.
Each base model comes in 4 flavors. Two of those 'flavors' have dimmer controls built into the driver.
If your configuration has easy access to the drivers, it can be much easier to avoid attaching and mounting a dimmer and just go with the adjustment screws on the driver directly.
Meanwell driver ID - Last characters in name (A, B, AB, or blank)
A - Built in dimming
B - External dimming
AB - Both
Blank - No dimming options

Well, I checked them out, found their eBay store and just got my offer for two 288 V2 LED Board + Heatsink (3000K) Full Spectrum LM301B accepted (the same price, offered/accepted, that's on their website but got free shipping).
Does anyone have a schematic they can post?

Thank you for the tip for where to go. One question though: I'm pretty sure I want to hook them up in series, is that correct?

they also have schematic for parallel too
parallel totally ok
series or paeallel it's all how you want to wire it up
check ledgardener.com or growerlights.com for wiring ideas bro

Thanks again; ledgardener seems to be a great site for info. I'm going with series as it will prevent damage to the remaining board if one board fails.they also have schematic for parallel too

series is most popular way to do it
parallel is good for large setups
