Bueno Time I found the prices on mouser, sounds like there is no reason to pay more than 60% extra money for 3% efficiency...Thanks!
Looks like I am going to buy 6 Z4's (if I won't find cheaper AB's), any suggestions what driver to choose? Buy a single for every unit? Or one that can support multiple units?
Finally! After 4 years break, can't wait to grow some plants again!
One of the coolest things is that by improving driver efficiency ~5%(based on load) will give you the same as increasing a bin instead of the driver.
Z4's on HLG185's will run about the same as an AB's on LPC or anything in the 86-87% range when driving @1.4a.
So if you count the driver efficiency(your electric meter does)...

Chip efficiency only 6674lm/52.22w...127.8lm/w...÷ by 325(the LER) =
39.32%
On an LPC running 87% efficiency... 52.22*1.13=59w... 6674lm÷59w= 113.12lm/w...÷ by the LER(325)=
34.8%
On an HLG running 94% efficiency... 52.22w*1.06=55.35w...6674lm÷55.35w=120.58lm/w...÷ by LER=
37.1%

On LPC running 87% efficiency... 52.22*1.13=59w... 7140lm÷59w= 121.02lm/w...÷ by the LER(325)=
37.24%
On HLG running 94% efficiency... 52.22w*1.06=55.35w...7140lm÷55.35w=129lm/w...÷ by LER=
39.69%
Just to clarify something...the AB has ~2.47% higher efficiency at 1.4a...BUT that means a ~7% increase in light over the Z4....
7140-6674=466...466÷6674= .0698...or 6.98%. I'm not saying that justifies going AB in your case...but that it is more than a simple 3% increase.
Mouser is a rip off...but they are the only one who has singles...so it's like 15$ beers at a ball game.
Good luck man, I think the 6 Z4's is a smart choice, and in the end will be better if you pair it right, plus you can spread more.
