Anyone have data for all three types?
Someone told me to divide lm/W with 324... But I think this is wrong. C type driven at 800mA only 59% efficient? No way.

192 lm/W divided by 324 = 59% efficiency

Only 59%? That's pretty good. So what is the K and CRI of the cob in question?

Btw, what is better option for all around COB (for veg and flower)?

3500K 90 CRI (more reds because of higher CRI)
3000K 80 CRI (more reds because of lower K)

Or... something else, like:
- 3500K 80 CRI

The 192 lm/watt looks about right at 800 ma. I have the Vero 29s 3500K/80cri version 6 and they do it all. I'm very happy with that choice.

As for the 80/90 CRI choice...there looks to be a growing (no pun intended) body of evidence that the 90 CRI benefits from the Emerson effect and actually out performs the 80 CRI. If I was buying today I'd be leaning towards the 90 CRI.

Have you already bought them?

No, I am at 90% of buying them.
Will buy Vero 29 gen 7, because they are cheap and the same efficient as 1825 or 3590, but cheaper. Just don't know if I go with 80 or 90 CRI...

BTW, anyone have spectrum graph for gen 7?

I have Vero29 gen7 "30E10K0C726QK05600121652" According to the QR code.
I got them from jerry en he said is the Type C SE Version 3000K.
What is the difference between the SE version and the normal one? Can be CRI?
I need to know the efficiency of this COB at 1400mA, who helps me please :clap:.

I plan to run 2 of these COB at 1400mA, as timber does, to make the 400W whit 4 of them.
Is the wiring in serial or parallel?

Hi
the SE Version has Poke-in connectivity enables solderless, connector free installation. With high ratings for the holder (500V)
The normal Vero you need to solder or a molex connector.

This number(QR CODE) looks strange, do you have allready this Vero 29 gen 7 at home? Normally there is a number under the COB it self at Veros. Th Veros SE have even a number on the Top of the cobholder. Tell us that number and we should tell you what cob you have.

Vero SE gen 7 and normal Vero gen 7 have both same efficiency, if you compare Vero 29 C or Vero SE 29 C.

You don't "need to know efficiency at 1400ma" you already bought the chips...

Get the ~140v hlg 185 or 240 and wire them in series and call it a day.

@Malocan, sorry bro, i type wrong the code, i edit first post.
@Shugglet Man, this forum is about efficiency. I only want to know the numbers at 1400mA with 2 chips on HLG-185-C1400A. And how to connect them.

Thanks to both, this COB is really nice.
I never had a Vero29 in my hands, just

The thing is you already made your purchases so knowing the efficiency is quite pointless. Now I'd just assume you want to justify your purchases to know you made the right choice. You did. Knowing the efficiency changes nothing.

And if you read my previous post I answered the only other question you had... wire them in series and call it a day...

You won't find a definitive concensus for your queston. Sorry bud. I was in your shoes and went with an equal mix of 3500k 80cri and 3000k 90cri. This discussion is far more theory based than anything else and you've already touched on the theory behind it so now you just have to pull the trigger. Either way it will be fine.

The nice part is, you can always swap out cobs on the existing drivers if you're not happy with results.

Can you mix at the same driver 3500K 80 CRI and 3000K 90 CRI?

Wiring in parallel the voltages have to match up but I'll tell you right now you'll have fun finding a driver that will push Vero 29 Cs in parallel

with a cv type of driver...not true with cc there are many options

You can mix and match any LEDs when wired in series... matching up the currents is all you would have to worry about.

So yes.

take thiswith a grain of salt....usually this is the case...but you haveto test. it is not an accurate statement all the time....thermal runawaycan happen in cc mode too

Hola, lo siento por mi Inglés es malo, necesito saber datashets de mazorca llevado vero29 7mA 3000k generación, ahora yo no lo está tanto más cri mejor en este LED 80 ?, que iba comprar cree llevado 3500k mazorca, pero es más spensive de veros, necesito "continuo", 700mA en vege y 1050 en la floración pero no sé Qer, effecienci (%) de C / U (1 unidad) para PPFD calcular con Cree que sé con el mesa, alguien tiene cualquier tabla cómo leds 3500k mazorcas ?.
estafar que la información que puedo calculate PPFD.

I have 2 options for indoor, 2 m2 or 1.44 m2 with 12 cobs in 1.44m2 is very good but for 2m2 maybe i need 16 cobs? but my questions for 2m2 is distribution space for cobs (1 cob use 0.33x0.33cm? is more better 2.00 mts x 1.00 mts? or 1.50 x 1.30

Gracias por ayudarme, y lo siento por mi Inglés.
