K well I did some more searching and came up with this let me know what you think.
2x = Mean Well HLG-185H-C1050A 200W
8x = Citizen CLU048-1212
2x = 24inch 4.850" WIDE EXTRUDED ALUMINUM HEATSINK
2x = 120mm fan for cooling each sink.
So I can hit 200 watt using all 8 cobs to one driver or 4 cobs to a driver and achieve 400 watt
What ya'll think and man you guys have been more informative then these other forums jeez glad I joined.
O and remember I am putting all of this in a 2x2x4 not a 3x3 .. I will be flowering in the 2x2 I have another 2x2 on the way for my veg. 3x3 to BIG for my closet lol saving her for when I move. Currently flowering a bagseed that I liked 2nd run and this 150hps aint cuttin it for me lol especially with the small space closet lol.
Here are some pics shot today
Hmm so yeah my bad I can't put 8 to a single c1050 lol but i can put 4 and run 2 of them to achieve 400 ?
I think you're in good shape. I just guessed on the spectrum and cri, not sure what you're looking at. If flowering only, I recommend 3000k 80 cri for the 1212's. Where are you going to buy from?

Nice info there so thats my info on 8 cobs 1 driver at 1050ma so what you think I can pull using that in a 2x2
thats the million dollar question my man! depends on many things, but if you're looking for personal only, you'll have plenty.
So both tents can have that each so veg at 200 and flower at 200. Unless I should put more watts to the flower and decrease the veg watts remember I will have total 8 clu048 1212s.
This is a good plan. Looks like your plant still has at last 2-3 weeks to go
people run 3500k for veg and flower, so if you have those already, I would just use more of themSo I have 3500k spec on the cobs for flower what is a good one for veg thanks is it same 6700k
Watts/$?Anyone have any feedback on these Home Depot LEDs I want to use them for clones and moms
