I have been flowering with the 3000K vero29 and whichever plant I put under! Lots more stretch! I am thinking 4000K for the Bridgelux would be dominant flowering temperature.

I run 3 5k's and 6 3k's. Love them. Tight buds.

I am extremely pleased with my 4000k for both flowering and veg. The 4000k are also significantly more efficient then the lower K values, more light intensity for the same amount of power.

lol, I've had little stretch using 3000K Veros.
Where does that leave us? This question need some rigorous testing to get an answer. I'm going to guess they all have enough blue to prevent excessive stretching.
Out of 5 strains so far, I have had one with significant stretch but should note that it seems to be an anomaly as I had grown the same strain (from the same mother) with 3350K and had little stretching. Also, that grow with the excessive stretch provided my best GPW to date.
Edit: Worth noting, I don't know what Bridgelux did but the efficiency between color temps in Vero V2 is all very close, minus the 2700K variant.

I'd like to try a 3500K+4000K combo out some day, with a 2:1 ratio.

Indeed Rahz you are correct the newer version seems to have closer output value per watt then the older ones:

5000K and 2700K hold last in efficency in comparison to 3000K-4000K, with 4000K being the most efficient (more blue, less yellow-phosphorus). 5000K didn't get much of a boost, if any at all, with this last version update.
Jindica, you can't go wrong with 4000K for vegetation through flowering. If you looking to try something new and quite possibly more effective during budding, consider a 2:1 ratio of 3500K+4000K.

These are some plants that are vegging under the 4000k. As you can see, nice tight nodes, very bushy, topped the two in back a few days ago. The ones in front just got moved from smaller pots today.
These ladies are from clones, they just got hardcore trimmed two days ago and lights changed to 12/12 on the day of the picture. They were also vegged under the 4000k. They will be flowered under the 4000k as well.
I expect they will stretch out and double in height? We will see this is only my second indoor grow
Pretty happy with how things are looking on these ladies so far.

I agree! U made the right full cycle choice with the 4kThese are some plants that are vegging under the 4000k. As you can see, nice tight nodes, very bushy, topped the two in back a few days ago. The ones in front just got moved from smaller pots today.

I'm not fully convinced on 4000K being ideal in all situations, though I understand there are scientifically proven benefits to both deeper reds and near UV in this regard. I've chosen 3000K because of it's warmth and with efficacy similar to the cooler emitters, though I'm not convinced my opinion isn't biased on a limited data set and theories. To truly answer the question of the OP two lamps with same PPFD would need to be ran against each other several times.
I think a certain amount of stretch is good for maximizing yield if it can get the apical flowers above the canopy, and it's also useful for producing a fast veg. Both of those might be valid concerns in a SCROG for instance. In other situations neither of those may be as relevant. Quality is a different matter, and while I don't have the full range of personal experience, you can't really go wrong with 3000. If there's some difference I guess it will be very small.

It's been expressed several times the similarities between 4000 Vero and 3000 Cree but I've scored some 3500 Vero that'll I'll be flowering next. Originally i had 2700 mixed with 4000 at 1:2 with good results still less stretchy then my ushio setup

With 3500K vero and 3000k cxb in the same room (both 80cri), the vero 3500k is noticeably more blue. I don't think 4000k vero is a good comparison to 3000k cxb. I also have 3000k vero and judging by tinge, it's much closer to 3000k cxb than 3500k.

Would you still consider the 4000k vero 29 v2 good for both flower and veg?

I don't know. I've never tried vero 29 4000k. They all seem to work to me. I don't have enough grows with any one SPD to know which is really the best.

i kinda wondered about this as i don't own any Cree yet but just looking at hue of light seems like a dangerous game i imagine that they can have similar ratios of output while being visibly different

Which version of Veros do you have? Different versions have different spectra.

5000K was the most efficient in the last version for Vero 18 but it didn't get any boost with the version two. I'm going by the LER (334 for 5000K) Supra provided and using the data right off the new datasheet Bridgelux provides.
I didn't do calculations for the other Vero makes (10, 13, 29), so maybe the other makes got a little boosty boost?
