Would you consider buying a VERO after reading through some of the posts?

Just finished building 2 more, first was 240 watts, second was 243 watts and third is pulling 244 watts, still does not look as bright as the 4000k d version lol

Yeah, it has to be the color temp difference from my cxb 3590's, which are 3500k, the cree's look whiter, which in turn makes em look brighter to em. I have the 2 new vero fixtures over 4 x 4's, swapped out hps se 1000's, we'll see in a couple months how they performed. :)

I need a little bit of help. I built a light with 4 x CXB3590, 3500k running at 1750 mA. My grow closet is 3 x 3. So, the light is drawing about 260 - 280 W at the wall. I'm thinking about adding a couple more COBs to get my power up to around 40Watts per sq. Foot. I'm thinking about using Vero 29. But, I'm wondering what temp. would make sense to augment the 3500K. Should I go 3000k? Or is that just too similar to 3500k? Should I maybe go 2700k or maybe even warmer? Or do I maybe add some blue 4000k? I'm leaning toward the addition of warmer COBs for flower because the 3500k covers me in veg. I have those on a dimmer and the two new COBs will be on a separate dimmer so I can mix the spectrum in different phases of grow. Thoughts?

I would go with some 2700k 90cri should help with flowering.

Do you have a voltage and amperage you like? I know the Veros come in three different volts.

My veros are pretty old gen 5 is what i am running a equal mix of 2700k and 3000k 80 cri. So I have not ran any of the newer ones. Really it depends on how many watts you want to run them. 40watts s/f would be 360 watts total for a 3x3. So it looks like your wanting to add a 100watts.

Well I could use the 38v chip driven at 1400 mA or I could use the 52v chip driven at 1050 mA. But, is it better to drive the Vero 29s harder or softer? I've heard from others on here that Veros shine when driven harder.

I agree with JavaCo. There's some indication that 3000K high CRI is the way to go so mixing some 2700K 90CRI with your 3500K would be a good deal.

That was the mantra back in the day, drive Vero's hard because they were good chips but couldn't keep up with CXBs at low currents. They do have a nice thermal package but will benefit from lower currents just like other cobs. If you're wanting to bump your wattage from high 200s to high 300s, consider running 2 or 3 Vero29 C (67v) at 700ma using an HLG-120H-C700, would give you an extra 90-135 watts, very efficiently.

Ah, okay. Thanks, that makes sense. I think that's the plan then.

Any idea where to get the 2700k higher voltage chips? I looked on all the usual websites and can't find these. I can find the 2700k 38v versions, but not the higher voltage.

Valid point. Digikey is still calling Vero gen7 a "new product" every time I order them and they're still not stocking quantity of the 3000K variants. Plus I counted once and not including the SE variants there are like 107 different Veros to choose from so the odd ones will always be difficult to dig up. I think unless one of the DIY component distributors decides to stock them you will have to use the 38v version or choose a Citi product like the 1212 or 1825.

You have any 3500k gen 7 80 cri C versions available to sell, like 9 of em maybe? Can't find any of those in stock either. BXRC-35E10K0-C-7x

I don't. I have some gen7 3000/80 I could let go of but they're available online as well. I would use them for veg and flower before using 3500, food for thought.

I have a couple 3000k 80 cri c's flower fixtures I just built this week (2 9 cob fixtures).. I wanted to build a 3500k one to compare it to the vero 3000k and my cree cxb 3590 3500k fixtures.

I just ordered 6 3000k gen 7's 80 cri C's and 4 gen 7 3000k 90 cri C's.. going to build a 10 cob mix of 80 and 90 cri and run em at 100 watts each over a 4 x 4, see how that does, doing it this way because I just ordered 1750b drivers to upgrade my cree 3590 fixtures to run at 62 watts each instead of 50 watts and will have the 6 hlg 185 1400b's doing nothing, going to use 5 of them to power this new fixture... should do nicely :)

Vero 29 bin numbers... I noticed there are three bins... 2, 3 and 4. I was looking around for either 3000k or 2700k with the top bin 2 and it doesn't look like anybody has these in stock. Am I missing something? Why am I having such a hard time finding these in stock?

By the way, I am looking for the 90 cri versions.
