Replacing my 600w hps with CBX3590 Cobs. Need help!

[Actionbone]

Thanks a Lot for your time and patience @bicit !
You were very helpful mate. Cheers

One last thing 950 PPFD total right, both lamps at full chat?

654w at the plug 12cobs + 12 artic alpine headsiks.

Great setup man!

Well, I guess it is time to call our friend Jerry... lol

 

[Actionbone]

Get 3500k or 4000k if you run pure sativas!!

 

[Vescovi]

I'd go with his setup, since 3 drivers will be cheaper than 4.

Yes! Maybe I'll go for 3 lamps of 4 COBs... One less Heatsink also...
I don't think it will hurt the light spread... Do you?

 

[Vescovi]

Is that right? Why is that? Jerry only has 4000k's. Now you got me intrigued!

 

[Actionbone]

I have cxb3590 3000k And with sativas i have little strech so 3500k or 4000k with some more blue will help.

I think it'll be pretty close to perfect.

I second the recommendation for 3500k emitters.

Oh, Ok... I go 50 shades on them and just tie and LST. But good to know man!!! Thanks!

What do you think @bicit 50/50% 3000/4000k? Since I can't find the bloody 3500k.

If you can do 3500k I don't see why you want to mix, better color distribution if you go only 3500k

Is just that Jerry almost never has them in stock. And he has great prices and bins.
I will try and ask him for these babies...

 

[Actionbone]

3000+4000k will work well but if you can get 3500k instead

Thanks amigo... I'll try.
People here (my country) have been cheated left and right by 1000 dollar chine$e panels that yielded 50 grams in 3x3's.
Myself included. I can't wait to build these new CREED cob pannels. Reading all the buzz since the veros and 3070s.

Watching endlessly @Greengenes707 's channel...

Finally... I think we are on the verge of HPS extinction. I am going forward with this project, and I don't think this time I'll be sad at the end of four months.

PS: I almost had a fire 'cause of a F***ing ballast, scared the bejesus out of me. And I have fires in my stomach when the energy bill arrives. So Fu** HPS&MH!

Do you guys think I need 80 degrees lenses or reflectors? @Actionbone @bicit

 

[Actionbone]

I didn't have, but seems to improve the light spread, if you can go for it, 80/90 degrees seems to be perfect

Cheers mate!

 

[Vescovi]

Jerry will have 3500k but only 36V. F.F. Sake

10 days to 72V CB or CD bin, what is the best?

Reserved 12 cd bin 72V.

Not really needed. But if you wanted more distance from the canopy they're good for reducing lost photons

Reserved 12 cd bin 72V.

3x 72V CXB3590 + HLG-120H-C700
3x 36V CXB3590 + HLG-120H-C1400
These two options are basically one and the same setup. Same efficiency same draw...

The CD bin is better.

@bicit
Can I use 8 CXB3590 COBS with two MW 185 700b?
What wattage and PPFD a bar like this would have?

 

[nogod_]

Going to be cutting it close....
286v max for that model dont know if anyone has tried squeezing 288v draw on 185h-c700 but seem to remember it being a hard cap.
