...All Things Vero...

[Trippyness]

in the US at least the 50V is same price as 36V and much higher efficiency

This is true, however youll have to factor in extra driver cost.
I personally dont think efficiency is the top priority.
Highest PPFD over 900 with lowest wattage and good coverage.
Personally I think 1.4A or 2.1A are best bang for buck and efficiency with regards to PPFD.
All comes down to your goals.
For comparison here is an example:
3 x 3 Space 9 Sq/F
$35 CAD a COB
Power cost per kw/h 10.5
30 Day 18 Hours on Cycle

0.7A
PPFD 933 AVG
400 COB Watts
16 COBS Needed
Cost: $560
Power Cost $23

1.05A
PPFD 944 AVG
420 COB Watts
10 COBS Needed
Cost $350
Power Cost $24

1.4A
PPFD 1010 AVG
465 COB Watts
9 COBS Needed
Cost $315
Power Cost $26.75

2.1A
PPFD 966 AVG
480 COB Watts
6 COBS Needed
Cost $210
Power Cost $27.6

As you can see above the power cost is not a factor at all here. Not much fluctuation, which means in the lower Amperage your paying significantly more for negligible savings.
I would suggest 1.4A or 2.1A depending on budget.
Will get killer PPFD with either setup, just a bit better uniformity with 1.4A due to having 1 COB a SQ/F

I hope this was helpful for someone.

The numbers were taken from Canadian prices and my electric cost.

Just want people to understand that efficiency isnt everything and if its even worth the extra cost. For me it isnt.

I used the COB Calculator if you want to use it its here: Calculator

however youll have to factor in extra driver cost.

drivers for 50V cobs cost exactly the same in both CV and CC models (for meanwell at least)

if you can buy 50V chips and run them at 1050 vs 36V chips at 1400, they are the same wattage, same cost, the 50W put out several percent more light at the same wattage

i think thats a fairly obvious advantage with no downsides

Your correct, only issues is fitting less COBS per driver.
Like i stated above, cost does come in at some point.
900PPFD is 900PPFD regardless of how you look at it. Just how many COBS, drivers and wattage to get there.
If you have the extra cash yeah for sure grab the 50v Vero!
Just wanted to ad by 0.02 plus to show the very low wattage differance between the amerpages in a specific setup for small gians.
I do agree the higher voltage are worth it if you have the change for the drivers and if they are stocked.

As you can see above the power cost is not a factor at all here.

assuming you are running that rig for less than 3 years and then throwing the cobs away

the difference between 1050 and 2100 mA - those extra cobs pay for themselves in 3 years which isnt bad for a component with a useful life of 10-20 years

not even considering the extra cost if you need to cool that space. im assuming you adjusted Tj for the higher currents as well

lets call heatsink cost a wash because heatsinks for 40W cobs are about 1/2 the cost of heatsinks for 80W cobs

 

[CobKits]

Your correcte output per cob = more product , only issues is fitting less COBS per driver.

non issue because for a given series (like hlg240h-C), the 1050 mA model holds as many 50v cobs as the 1400 mA model does for 36V cobs

If you have the extra cash yeah for sure grab the 50v Vero!

again im talking
same # of cobs
same # of heatsinks/holders reflectors
same cost per cob
same wattage per cob
same driver cost per cob

with all the above being equal, more PAR per cob - more product

the 36V vero has zero advantage unless youre already married into 36V constant voltage drivers (uncommon)

In 5 years time we will have new better COBS and the older ones will be very cheap.
(market is crashing already)
Im well aware of heatinking costs.
I am just putting things out there.
If he wants to go passive heatsinking then yes his cost will be more.
Active not so much.
Threre are two sides to this.
Im aware of the full costs, however you can get there with less $ high PPFD with a little more wattage.
Personally wattage isnt as much of a concern as COB price.
I can get heatsinks reasonably here in Canada and throiugh active fans for cheap with a cheap 12v driver.

im not framiliar wtih the 50v at certian TJ as you.

Anyways, not here to have an argument on which is better, its obvious which is better overall.
My point is there are better setups for certain people with certain budgets who still want high PPFD.

That is my main point.

That is a different COB... 36v vs 72v.

Also, I have to agree with Cobkits as far as there being next to no reason to pick the 36v version over the 50v version. The 72v is a different story though.

Didi not see that.
Just went back and did some calculations are yeah CobKits is correct on the 50v version.
I was thinking in my mind 72v the whole time, (too stoned).

 

[Rocket Soul]

Hey Trippyness and everybody else,
I wanted to buy veros from china but now when it comes to bin, Im unsure which is the best (the c version) also which is the most efficient (36v or 72v ? and have availible good priced drivers in EU?
KB previously recommended that I should use

• 3x hlg/185h/c1050 ( I would preffer the b version if it is that one where you can attach the potenciometer) for running 15 vero v7 cobs - 5cobs each driver running at 40ww ( I have no idea which bin the KB have)
  
• I dont know if its a good driver for my setup, I dont want to overdrive the drivers or harm the cobs by doing that .
• 
  Please Malocan, Rcoket Soul, optzulu, CobKits, I know its been a few days when you talekd about group buy.I would gladly enjoy the group and buy 15 pieces /10x 3000k 5x 5000k if possible.
  
• Alesh please where did you get your drivers?

I would really appreciate the advice and help and finally It would be possible forr me to fully join an contribute to community

Hey man

We where taliking about a very special cct vero of 1700k, very heavy on red which wouldnt be available in less than 50 units. But its still not in stock anywhere as far as i know. For standard veros just go for digikeys, no moq just make sure you buy for over 50euros for free shipping and be prepped to pay vat on arrival. At least thats the way it works here in spain. I think digikeys handle the whole customs import procedure so thats one less hassle. Dont seem to be that much savings in buying many

 

[OLD MOTHER SATIVA]

i am from Canada too..its 26cents+ a kwh in Ontario..thats why i am trying to get the cob thing going here

 

[DrBlaze]

I can get heatsinks reasonably here in Canada

Cmon share the info

Fuck Yeah I lived there 2 years ago.
Fuck Hydro One....
Prices are going up aparently.
At those prices running at .7ma is well worth the price.

so that could possibly be a wild flower machine?

 

[Rocket Soul]

so that could possibly be a wild flower machine?

I guess. Would have to be tried before anything. Take a look at the vero decor DS, the spectrum is off the charts. Red peak atound 640-650 nm with only a little nipple of a blue bump. Low lums, but the spectrum isnt that bright to start with as it very heavy on red. My idea was to be able to bring it in when strech stopped in flowering, especially since our grow is sog so we be lookin for heavy top colas mainly. But until available for purchase its all just a smoke dream

 

[optzulu]

should be working fine.

305volt output from driver / 67volt(vero29c) = 4,55

Do You think adding a extra citizen clu48-1212 to it will work? I came up in 304.6V in total.
4x67+36.6=304.6

I want to build 3 fixtures and One fixture Will have 3 high cri 1212 in the mix.

 

[medicinalguy]

Trippyness I really appreciate the great input about efficiency, now Im deciding which option would be better when it comes to drivers, Im in Eu and I want to buy them here, because as you said customs are byrocratical piece of greedy shit. Lol I always tried to hassle them, but nowadays its hard especially with carriers like dhl which are waiting for your package just to put fee on it. However I dont know where to buy the new v29s in here and in that version, that you have suggested before (anybody in eu that know where to look Alesh maybe ?) If that would not be an option I get it shipped with low value from KB(does he have the exact version) the prices on drivers he have are great too about half cheaper than they are going here, but I guess it depends on the model of the driver) I would be very thankful If somebody can help me to choose the right driver.
It would be actively cooled by artic +
Thank you guys and have a great day

Hey guys new here.

I have a 5' wide x 5 wide x 8' high tent

I was considering a Cob setup and was looking at building 4 frames that are 2 x 2 feet and placing a cob in each corner of the frame. That would be 4 Cobs per frame which is 16 Cobs.

I was gonna buy Vero29 Cobs at 3000k for these 4 frames and this would be for Flowering and vegging too.

Then i was also gonna build another 2 x 2 foot frame and install 4 Cobs like the other other ones i wanna make, so thats 4 Cobs 1 in each corner but using the Vero29 4000k Cobs. This would be for the main vegging and turn it off when i flower.

Or i was gonna put 5 Cobs per Frame so thats 4 frames only and 5 Cobs.. 4 being 3000k and 1 in the middle is 4000k and run then all through the entire grow.

What do you think and how much heat will this be?
