building my first COB 3590 setup. please help

[weed-whacker]

lots of help already here but i will share what i think


i think you have a pretty good basic set up, BUT if i were you I would take the new vero gen 7(because they are cheaper and offer similar performance)
then i would put only 4 of them on each of those drivers(80ish watts each)
and this would save a bunch on heatsinks, cables, lenses, screws and mostly cobs

when u talking about similar performance, in witch way mean?
i do see people talking about new COB with better numbers then CXB3590, but i dont actually fine people talking how much weight they getting.

@Evil-Mobo said to use same driver 320-c1050mA with 4) cxb3590 3500k.(sound good and get me thinking, for the saving and the mA for COB)
witch i understand i will have more mA for each COB, and i believe the mA is the current,the waight we get in the end, is that right?
in witch other way changing COB to vero gen 7, beside the saving, will be better?

I wan the best on my set up, i been doing HPS fot the pass years and im done. im doing everything LED now.

keep teaching me guys

maybe u misunderstood @Evil-Mobo ? or are you talking about using the 72v version? anyway 36v@2100mA=72v@1050mA

so 75 watts and 154.6 Lumens per watt for cree VS 81,3 watts of 155 lumens per watt with vero

vero is cheaper, slightly better performance and u will fill the drivers out a bit more taking ur total system costs down

vero 29



cree 3590

 

[Evil-Mobo]

Negative I stated 36v cobs with the hlg 320-C2100B not the 1050 and I am running 3000K 80 CRI because I could not find the 70cri

Are thee numbers from the new Vero correct?
The 3000K have the same specs and that makes me wonder

c2100b even better, more current... im thinking about the idea, in the end im planning to use dimmer on everything, and in the end i can always expand

That's precisely what I did you can always dim down

So what about on heatsink, u have to use the TTS140??
& do u know about any other cheaper brand or alibaba saler for heatsinks? or just go with TTS?

lumens per watt or par per wat

dont pay do much attention to what others are yielding, it means little to your garden

new 36V vero does top CXB slightly in my tests

 

[bassman999]

Looks like Same lm/w except the Vero does it at double the current, thats a big difference.

I under drive more than most and still barely yield what others do and usually less.
Environment and grower skills are the biggest factor in yield I think.

Yes 140MM heat sinks a must my parts all came from northern grow lights email @robincnn for parts or contact @CobKits my 3590's came from him............

 

[CobKits]

Looks like Same lm/w except the Vero does it at double the current, thats a big difference.

my basis is PAR and/or lumens per watt at a given wattage. all cobs put out 150 lm/W at *some* current

 

[CobKits]

lumens per watt per dollar more specifically

 

[jaa soo]

Looks like Same lm/w except the Vero does it at double the current, thats a big difference.

so do you think is a vero model better then cxb3590? u see to be the one who understand all the number and what work best for yield, i just know about the lumens and current Ma.

I dont know for sure honestly, they do appear more efficient on paper.

This is my new plan, taking you guys sugestion and mixing my idea.
2) HLG-320-C1050B(8cob each, for the edge of the tent)
2) HLG-320-C2100B(4cob on each, for the middle of the tent)
24) CREE CXB3590 3500K CD 36V 80CRI, CXB3590-0000-000N0HCD35G
24) CREE 3590 LED holder, Ideal 50-2303CR
18 ) LED glass lens 60 degree(for the edge of the tent)
8 ) 180mm pin fin heatisnk for CREE CXB3590 95-105W
16) 133mm pin fin heatisnk for CREE CXB3590 95-105W
24) Thermal adhesive tape for cxb3590

105s are about 40W heatsinks, 120s like 55W, 140s like 75W

This is for all PIN heatsinks, or just for northengrowlights selling ? Evil-Mojo says SST-140mm (designed to dissipate approx 50w), is enough to dissipate the 75.5w at 2100am. My question is, i really need a larger/heavy heatsink like 163mm, designed to dissipate between 75 and 85w, or a 150 mm heatsink, designed to dissipate 60-70w have enough?

From Jerry (kingbrite) :

• Φ120mm*H70mm(for 40-50W): $9.5usd/pcs
• Φ133mm*H70mm(for 50-60W): $10.5usd/pcs
• Φ150mm*H70mm(for 60-70W): $13.5usd/pcs
• Φ163mm*H70mm(for 75-85W):: $15.5usd/pcs
• Φ180mm*H70mm(for 95-105W): $17.5usd/pcs
