yeah you right , 4000k have same red once passed 610-620nm ~ , but lot of more i think ill choose 4000kThere's been a lot of discussion about CRI - the general consensus is that the higher CRI cobs may have a slightly better spectrum, but give up a lot of efficiency in the process. Basically the higher CRI cobs put out less light, so it's better to go with the lower CRI cob that puts out more photons. I don't think the decor series is available anywhere, so that's a problem too.
The Vero 29 3000k v2 puts out a lot of red and will work good for flower - it's what I"m using now, but I supplemented mine with some royal blue 3 watt LEDs since the 3000k v2 is pretty low in the blue spectrum (less blue than the Cree CXB 3000k cobs). The Vero 29 4000k is popular too - it's got a good red spectrum with a bit more blue than the 3000k. If I were to build a light today, I'd probably go with 4000k Vero 29 or 3500k Cree for flowering. If you want an HPS like spectrum, go with the 3000k Vero 29.
like can make veg and bloom without changed lamp .
Thx
