Boards can be wiredin parallel. That way the DC voltage is not too high.

These Molex connectors are rated 9Amps and max 300V

For series connection you can connect up to 2 boards in series. The voltage is higher than parallel, other than that this config works fine too.

However do not connect 3 boards in series. That exceeds connector voltage and i don't like playing with 300+ DC voltage unless I am building a time machine or particle accelerator.

I think they look great....seems like a great idea....Quantum Boards...yeah...I think I heard someone say they are like a Nextlight deconstructed! Nice! I was going to check into a Nextlight, actually...but if these boards turn out to be essentially the same thing, then I'm down to try...a LOT less expensive than a Nextlight! I would like to see a high-powered (driven hard) version, too. Fuck efficiency....j/k! ;)

Cool stuff.

DIY will *always* be a lot cheaper than a commercial fixture, and give you more control to tailor your design for efficiency or power

these boards seem relatively specific, above 150W a high power cob will be more economical

I would like to run 2 of these in a 2x2 if possible . I would be fine with 200w at the wall. I would like a driver that I could add to if needed. If the Mars 600 I have now does veg and flower I'm sure two of these could smoke that. Can a driver be ordered along with these boards or do we have to look elsewhere?

If you doing DIY and just need boards then ordering your own driver is the fastest way.
If you need @Stephenj37826 to install the boards on a plate for you then we can arrange the driver too. There will a cost added for assembly and it will take a few days. Steve may charge overtime if he has to work this Thursday.

Another custom design by @Stephenj37826
4 boards on a meanwell hlg 320h c2800a

3.3 I mean really 3.3 sqft. Not 3x3
Used 2 boards for that.

Boards are just like cobs. You can run a cob at 200 w for a 2x2 or 4 cobs at 50 w each for better efficiency

For 2x2 you can use 2 or 3 or 4 boards on a HLG-120H-C1400
4 boards will give max efficiency and most even spread but will cost the most.
2 boards also fine

Robin is this the driver your referring to ?
