those 3070's will not last long
Just pushed my order through. Happy growing, all.haha...you're very quick. They have been up for literally about an hour. Thermal pads for 10min.
That should be it for now.
I'm certainly going to have to wait another 2 weeks before I can order heatsinks and drivers. I can barely contain my excitement. Have a great Sunday night.haha...you're very quick. They have been up for literally about an hour. Thermal pads for 10min.

30-50 watts per sq foot. 4x4 = 16sqft ---- 480 to 800 watts. Some run their setup softer and keep the lights closer using passive or semi-passive cooling, some run hotter and use fully active cooling. The popular setup in the forums are to use 4 rows of four 3070's across a 4x4 tent. If you used the HLG-185H-C1400 driver per 4 cobs you'd get approximately 200w per row or 50w per cob. You could also use the HLG-185H-C700 and power 8 cobs at about 25w per cob. So, you could use 2 drivers or 4 drivers depending on how hard you want to push them.4ft x 4ftx 6.5ft tent. Can someone give me a little help selecting what will work within reason price wise? I have been eyeing the cxa3070s at 4000k. How many do you think I need? Drivers? Power Supply? I got plenty of heat sinks but how many fans should I run? Anything that is a must that I haven't mentioned?
The HLG-185-1400 would fit 3 cobs on it perfectly. The 1050 would be a fair bit less efficient.I'm going to build a six cob fixture out of CXB3070's. My thought is that I would run them with two HLG-120-1050's, 3 each. Would the HLG-185-1400 or 1050 be better? If so, why? Thanks!

My grow space will only be 2.5x2.5x4.5'. I was concerned 8 might be too much light. Why would I pick the 185 over the 120?In terms of what will work best for the drivers -
HLG-185-1400 fits 4 CXB 3070
HLG-185-1050 fits "5.5" CXB 3070 --->5
HLG-120-1050 fits "4.3" CXB 3070 --->4
HLG-120-1400 fits 3 CXB 3070
If you are fixed on 6 cobs, go for the HLG-120-1400
Why not purchase 2 more and use 2 HLG-185-1400 and run 8 cobs over your area? The HLG-185 drivers are about $5 more than the HLG-120's.
Best of luck.
Hey giant I'm in the same boat and was recommended a t2-2100 from tastyled.com for a 2x2.5 area. That's only running 2 Cobb CXB3590s. 165~ watt. You could view their specs for some inspiration for your DIYMy grow space will only be 2.5x2.5x4.5'. I was concerned 8 might be too much light. Why would I pick the 185 over the 120?
While I am technically minded, these correlations escape me. I've been researching this for weeks. I'm glad to know what a driver does but as far as the technical side of them, the info just won't sink in.
The level of expertise on this board regarding this topic is unbelievable. Reps to all..
Thanks @Bachomp. I like building things, projects and really wanted to build my own which doesn't look difficult to me. It looks like I can build twice the light for less doing it myself.Hey giant I'm in the same boat and was recommended a t2-2100 from tastyled.com for a 2x2.5 area.

I agree with you, 6 bulbs in that small tent is already giving you pretty much maximum spread. The drivers will also work fine, they just won't be as efficient as other choices. If you don't care so much about efficiency then there's no problemsMy grow space will only be 2.5x2.5x4.5'. I was concerned 8 might be too much light. Why would I pick the 185 over the 120?

I do care about efficiency so I guess the 185-1400 would be the most efficient way to go while giving me the option to add two more cob's if I want or upgrading to the 3590 if I want to. Every 36 months, these lights double in output according to Haitz so hopefully I'll be able to upgrade the cob's while continuing to use the same drivers.I agree with you, 6 bulbs in that small tent is already giving you pretty much maximum spread.

I should mention I plan to scrog alsoHey I have a 4x2 area, 8sqm. I'm a LED noob but looking to make the transition. I'd prefer buying a light than making (unless it's easy).
What type of light (wattage, company) should I be looking at to cover 3-4 plants?
I'd settle for 1-2 plant coverage if it comes with a significant price reduction.
Any help is appreciated
