OK, but you can just dim it down to the rated wattage if you were concerned with that.

That makes sense, However if using the same model COB it wouldn't be a problem I wouldn't think?

I understand how that could be a problem and I have heard a lot of people say that, I have 8 cobs connected to each 320, I would have to lose 5 out of 8 cobs before it became an issue, but I can understand how if you were driving your cob's to the max you could be in trouble if one fails, but if you are driving your cob's that hard in the first place your efficiency isn't much better than a HPS setup..

Yes, you are also right. There are several ways to avoid problems with parallel operation. As I said, it is just my personal decision to use no parallel circuit. Something else is series parallel switching (for instance 3S2P), but that is another matter.

Got any more details? Is that a creation of your own? Looks really nice.

I made this one but the concept isn't exactly revolutionary, as you can see above.
It uses single 52V Vero29 (3000K/90CRI) covered with Ledil Stella VSM optics, a 163 mm pin heat sink and MW HBG-100-60B driver. The frame is 20x20 mm aluminum extrusion and the pot is in a neat alu case I got from ebay.
The connection of the frame to the heat sink could be done better, though. Would be semi-pro looking then.

Having made the light in post #1654, alesh's design is much cleaner, and not just aesthetically. I put mine together using left over parts, but I'm already working on ways to reconfigure them (I made a pair) because they require too much vertical space in the tent -- I need them to be more compact. Basically I plan to tilt the heat sink 90º and add additional hanging points.

Nice work @alesh :)

Beauty. That's exactly what I want. How's everything? Lol temps, do the plants like it? If guy don't mind me asking, cost of build?

It's a sweet light. 320 watts in 9 square feet is dead on watt per square foot. The plants LOVE it. The tent does need cooling, but it needs air handling anyhow(you can see a carbon filter in that pic at the top of the tent).

Cost...
These things tend to NOT be cheap. What's the adage??? "You get what you pay for". So true with home made stuff.
About...
$65 each(X6) for the leds themselves(including the heatsink,mounts and reflector)
$110 for the power supply
$50 for the frame.

4 18" aluminum square stock attached to a laptop 4 fan cooling fan.
20x 12v 10w 3500k cob chips on a 203w 12v power supply
16x 12v 10w 3500k cob chips on a 175w 12v power supply. Each has its own switch as well as a switch for the supplemental blurple lighting. I can use different variations of lighting to my liking. The aluminum sq stock is watercooled as well tubing fit snugly thru the aluminum. Lines run into a beer cooler with a 1000gph sub pump with a 80mm pc fan intake fan w 2inch hose for cool air intake as well
