Nevergood's high power garden

Just my luck, none of the hole line up to this holder. What should I do? Build the Luna 2700k 90cri fixture with the parts I have and use the CLU550 on Flip Chip Opto's heatsinks later. Or do I drill and tap into the copper plate that is attached to the heatpipes and risk ruining it to get the CLU550 fixture running? I am leaning to the Luna build.

I ended up building the Luna 90cri. using 2 HLG320H-48Bs turned down to a total of 500 watts. While balancing the amp loads on 2 different breakers, I notice the 2 HLG240H-48B's were cooking. I was getting 550 watts, way past the 108%. I plugged in the dimmer and it dropped to 500 watts. Everything is loving the lights and I am loving the coco. I flushed them with rain water and gave them fresh food. I now have 2100 watts and the room is full. The second 200 watt light is over the 2'x4' tray with 6 new small girls. The center of the room, 6'x8' is covered by 2 500 watt fixtures. The 700 watter is back over the 4'x5' corner.

And the only way I could see your pics is in this reply... Before I posted it? Weird!

it is doing the same thing to me?

Not sure, your pics still aren't showing.

MUCH better! Looking good in there, too.

Hard to believe I did a heavy leaf clean up last Friday..

I couldn't help myself. NOT COB LEFT UNBUILT!! I just realized I do have one more CPU heat sink. I just threw the CLU550 together to see if I ruined it or not, and it is working fine. I was able to use the sandwich bracket for the chip. I am running it now to see how hot it will get. If it stays cool enough, I can do one more.

Light has been running for a while at 250 watts and the copper plate is still cold to the touch. That is either excellent or very bad. I think it is putting out 130,000 lux at around 22' without a reflector. Will not have a good comparison until 2 are mounted to a reflector. I am talking with multiple people about hoods, similar to what I have now but shorter and 2 angles designed for a 3'x3' @ around 24" with 250 watts or 28 watts per square foot.

Just received some more info on Citizens CLU056-
This is not the CLU550, but it is also impressive and will be trying a couple next week. I am thinking these around 100 watts each would be great for vegging and almost half the cost of the CLU550.

Flower day-17
I am hoping the stretch is done, but not problems yet. I did one last clean up on all the girls and completely filled a shopping bag with leaves. Not even a burnt tip yet. The group is in coco and is getting hand watered daily, 8 to 10 gallons every day. All the drivers are now on a titan 4 light 240 volt controller. I have already noticed the drivers seem cooler, maybe.

It is time to build some more lights. I will finally test the Citizen against the Luna and replace the 700 watt fixture I blew up. Yes I fried a turkey egg. While changing everything to a master light controller, I some how forgot to plug in the cooling system. Without the water moving it blew up. I knew that if the plugs weren't combined I would one day forget. The spread I am getting with the 2 hoods has been great. I only have 25 watts per square with 1000 watts. I kind of want to add one more to get to 37.5 watts per square foot, but I don't know if it is needed, yet. I finally refilled my CO2 tank and also add Heavy16 Fire to the mix. Wow, overnight I could see a difference, but I don't know what helped more. I also notice I was pulling almost 3X the water out of the air.
I will be trying the HBG240 on the Coolbays.

Cooling system? Water moving? Can you elaborate?

The 700 watt fixture used 2 watercooled CPU coolers. There is no easy way to mount them and I now have access to cheaper passive cooler with holes already in them.

@Alex Lau - I still need you to get me those 320 watt heat sinks as soon as possible. I know they will be fine on the Coolbays, but I have 3 HLG320s that I don't feel like dimming down and they run hotter than I like, even if they are safe. I also like that they are shorter. Do you have a Datasheet on the 320 heat sink?
I finished one of my replacements and I like how it came out, just a little taller than I like. I have to going to some friends to test, one is using only for vegging and the other wants to flower.
Mine are doing great and drinking a lot. The tallest girls are 50" not counting the pot. That light is almost against the ceiling. I ended up putting all the drivers back in the room. The heat coming off them while running 240v is not worth having longer cords on all my drivers.

Day 24? to tired to think. Is a little early to day, I do think I see a small edge in bud development under the 2700k 90+cri @ 250 watts each. The other side is a 4000k and 3000k 80cri. This is by no means a comparison, just an observation, I could be imagining it.
Another thing I an see is the 8 Vero 29s @ 25 watts are not building buds as good deeper in the canopy. Again this is a different strain and setup and they also look great this early in. The CLU550 4000k 70cri is much brighter that my other 200 watt Vero. Still haven't finished a complete fixture with these yet. But I am getting some CLU058 that run at 50 something volt instead of 108v.

Ok, I took a closer look between the 90cri 2700k and the 3000k and 4000k 80cri. It isn't that the buds are bigger, but the white hair on 90cri are twice as thick. It will be interesting to see a few weeks from now.
1000w 2 fixtures 25 to 31 watts per square foot (4 Luna 300)
660w one fixture 33 watts per square foot (2 Luna 300)
500w eventually it will be one fixture 42+ watts per square foot (2 CLU550 4000k 70+cri)
200w one heat sink sitting at a 45* angle? almost 4' (8 Vero 29 3000k 80cri)
As you can see, though, by no means scientific, but will get an idea what gets changed next. I just can't stop changing this.

I'm hearing you don't think water cooling like this is the best solution, then.
