Hi !
I figured I try and build a LED setup for myself to replace a 400HPS in my (2x2, pots are 10 liters) cabinet.
There is not too many ways to do this I guess. It's mainly five components.
COB, Heatsink, Fan, LED Driver, Fan Power
Everything but the cobs seems "pretty" straight forward to me. I realize that driving the cob properly etc. will benefit me.
Chinese stuff seems of, let's say lesser quality and the spec's are overrated. Atleast thats what I see when reading. But they are readily availible and "cheap".
Cree CXA 3070 seems to be a jewel if you can get one from a good bin. This seems very hard? and they are expensive.
Bridgelux has Vero 18 and Vero 29. I've never heard any bin talk about these? They seems availible and great...
Chosing one of these three cob seems like the way to go(?).
Simple comparison around 3000K:
I understand that there are LOTS of other parameters as well like what different wavelengths etc.
To build my setup to sustain myself with the 4 plants. What would you suggest??
I'am leaning towards the Vero 29.
The Vero 18 seems good too but I'm guessing I would need about 8 of those?
I was thinking that with other 100W cobs I could settle for 4 of them (total ~400W LED).
Any advice is greatly appreciated. Telling me that I am on the wrong track is also ok

Simple comparison around 3000K:
- CXA 3070 Z2 bin:103lm/W 7700 lm 2.8 A $46 (in 100 qt.)
- Vero 18: 122lm/W 3780 lm 1.05 A $13 (would need 2-3 to match the others)
- Vero 29: 125lm/W 10100 lm 2.1 A $30
- Aliexpress 125 lm/W 10000(?) lm $30
