The problem you run into is it takes a 230v 30 amp circuit to handle the inrush current of 3 of the drivers that large. We’re discussing options around it in 2 different threads, but I don’t believe anyone has a for sure it will work yet.
The hlg 320h-c1750 (I think that’s model) will run 3 of the qb 288 at a little over 90 watts. If you get the remote dimming driver and leave the dimming circuit open it would be closer to 100 watts per board. But that’s the only viable 6 boards on 2 drivers option I have found. Without connecting boards in parallel anyway, and I really really don’t like to do that.
When you take into consideration that as soon as they get the quantam boards in stock they immediately sell out, you’re almost better off going with a strip at that point. The diodes on the strips aren’t as condensed as the boards, but the strips are a lot cheaper. So if you’re worried about coverage, you could essentially cover the entire tent with them. Even though that would be way more than you need.
There are some really good cob options out there too. The cree’s are still pretty expensive, but citizen clu series and bridgelux Vero 29 perform very well at much cheaper price.
The pictures really don’t do them justice. On full power you can stand the light, but if you looked at the diodes you’d being seeing dots like weld flash pretty much instantly. They are bright!
