Thanks dude yeah, its a shame the seeds isn't found anywhere now..
No, the hydroton is my top layer only, to prevent evaporation. I grow in soil..
I have a plastic tray in the bottom of my tent which i water in.

Good idea with hydroton ..but you have problem with Tetranychus, low humidity in tent or bad sterilized of soil cause them, want it suitable spraying

Can any of you up to date techies recommend a driver for running 4 vero 18's at nominal current?

Vero 18's Nominal Test Current is 1.05A with a Forward Voltage of 29.5V using about 31W each.

Meanwell HLG-120H-C1050 is good up 150W so you could comfortably drive 4 chips on that driver.

Hope this helps.

Thanks brother @cdgmoney250

Does anyone have any experience running the Vero 29s above nominal drive current ratings? The project I am planning currently will incorporate them running at or near max current rating (4.2A for V6s) and was wondering if anyone had any experience with them and just how much heat they will be putting off. They will be water cooled though so I really dont anticipate heat being a problem. Ive had trouble finding anything on running them hard as everyone seems to like running them well below even the nominal ratings to gain efficiency, but I am far less concerned with efficiency that I am with raw output.

All things vero huh.......

Vero's are fucking hot! minus well run an air cooled d/e yeah?

CXB 3590's running cooler fasho.... CXA 3070's too.

How about the Citizens chips ?!?!??!?

1000W of hps, cmh, osram, cree, citizen, bridgelux, mars, kind, T5, incandescent, a hair dryer, toaster, etc all add 1000W of heat load to a room

minus well'd

V6 and V7 at up to 3A is below. i wouldnt run the V6 to 4.2A but the V7 would do better and would be about as efficient as a 3590 is when run at 3A

Doesnt the voltage of the new v7 vero's matter? I will likely be looking at the ~56v version

@robincnn

will ur site have the new verO? how Much?

did i hear you say all voltage variants will cost the same?

reconsidering citizen in favour of new vero BXRC-40E10K0-C-7X

@weed-whacker
Bridgelux has plenty of distributors already. Hard to buy them direct. I will not be stocking them. Will share an update if i see any at Jerry/Future/Digi.

I hear cost is same for Vero B and D around $21-$23. The 70V Vero C will be more expensive $28-$29
I have not been able to find the 90 CRI spectrum for bridgelux Vero 29. For 80 CRI i will go with Vero 29 instead of Citizen because i do not mind soldering and like the Vero 29 design.

Right is Gen 6, Left and center is Gen 7

Which one is what. find here

yeah those were based on 36V versions. from what i understand is unlike crees the different voltage veros are different die layouts and that 72V one sure looks like a beast

That's what was surprising about Citizen, how happy they were to support small vendors. It was a really nice surprise, especially compared to Cree where Jerry is the unofficial wholesaler, and Bridgelux who as you said seems to like selling to the big guys.

Hopefully we won't see the famous digikey markup on prices.

Supposedly the Citizen die layout is patented, but Bridgelux is cramming them in there just fine. I'm super excited to see these in the wild.

sorry for the interruption,but after hours of reading i cant tell if this one will power a single vero29 driven at 1,4A? they should run at ~51W put the driver only provides 50

No, it can power your single vero29 at 1,5A +-5%. .. So actually 1.425A-1.575A.

i just cant see that number being right...... the 72V data from both the datasheet and the simulator gives some really unrealistic numbers at low currents - like 250 lm/W and above. which would be a serious game changer but i see no reason why it would be so divergent from multiple manufacturers designs (including their own 36V V7 i tested), which converge at low currents. this was generated by simulator generated lumen values, which were equated to par intensity on my readings and finally normallized to ppfd/W

i mean i hope im wrong! but not getting my hopes up. based on the 324 LER of last gen vero at 4000K, if the new simulator was right this $27 72V chip would look something like

W efficiency
10 100%
15 85%
20 77%
30 69%
40 63.6%

low current data def screwy. i mean id love 75% efficiency @ $1/W but not holding my breath

Values used for this simulations, from datasheet i assume; which values do you use, 25° or 85°C case temp? Tc 25 would not be realistic values for use in a real setup. Looks a bit too good to be true although i believe the values will line up with the top numbers in ur comparison.

I can almost guarantee he used 85*C. He was talking just recently about how real world impossible running at 25*C even is.
