It's 14 bucks per COB, driven at 1050mA lumens per watt are equal to Vero V29 B gen 7 which is 22 bucks.

I will build all light for veg and flower, do you recommend 3500K maybe?

So, I will drive them with ELG-240-C1050A. I have around 25V space for ... I don't know, far red (660 or 730) maybe? Can you guys give me advice which ones and how to wire them on driver with Vero's?

With that driver you could go 2 strings in parallel consisting of 4 v22b and 1v22d in series. Each string of 5 would run at 525ma and peaks at 228vf. Colors are up to you, my preference is for a mix of 3000k in 80 and 90 cri. That may change after I try others like the lower ccts int he Decor series. You can pick and choose different colors on the same light if you want to hedge your bets.

4x COBs at 1050 mA is enough light for my space, because I have CXB3590 in tent already.
I just want optimize spectrum/light with 25V empty space on driver, so I will not go with 5x COB.

Anyone else opinion?

Anybody used the vero v22? Whats the solderless holder situation like? Thinking of getting 10 together on a big heatsink and run them in parallel and it seems like a lot of soldering for someone not used to it. Can you get them at digikey?

I've been looking at the V22's, did you end up getting them?

Digikey and Arrow should have them in stock. The heatsink depends on how hard you plan to drive them.
With up to 525mA you can get away with a ¼" thick alu plate and a few c-channels glued to the backside.
How many watts do you need for the final light and how big is your tent?

PS. Arrows search engine is a PITA, you need the correct part-numbers eg.
BXRE-30G4000-C-7X for V18, 3000°k, CRI90

I would take 20 Cree XP-E HE photored or Osram Oslon SSL120 horti, hyperred and run two strings of 10 in parallel. That's ~23,5v and each diode would run at 525mA, with ~55% eff. There are still a few volts left but I would leave them for coldstarts.

if your case temp is the same. v22s have smaller footprint than a vero 29 so will always run hotter at a given wattage, which means less light for you

Vero29 B and D have been $22-$23 since day 1

I've been lurking and learning from here, there and pretty well every forum about every MMJ topic for a bit. Information overload, that's what I'll blame it on. I could have sworn that I checked you guys out but apparently I flaked on that. Thanks, likely ordering soon!
