Hi guys

I'm looking into buying QB boards and I have 2 configurations I wanted to check with you all.
I will buy 2 heat sinks, depending on conf they will be either 940mm or 900mm in length.

Each heat sink will have 3 qb boards on them, the difference will be number of white Samsung lm301b and Cree 660nm leds.

The boards are 3500k so little more blue spectrum then 3000k and using extra the Cree 660nm will give more red spectrum for better bloom.


Conf1
2 heat sinks with 3 boards on each with 1512 lm301b leds AND 216 cree 660nm leds, total 1728 leds.
Each heat sink with 3 boards will have one HLG-320H-48B driver.

Conf2
2 heat sinks with 3 boards on each with 1728 lm301b leds AND 48 cree 660nm leds, total 1776 leds.
Each heat sink with 3 boards will have one HLG-320H-54B driver.


So as you can see Conf1 has 216 less lm301b leds BUT 168 more Cree 660nm leds AND total 48 leds more.


So my question is which one would you guys prefer and why?
Would you guys go for more (+216) lm301b leds and only having 48 Cree 660nm but also 48 more leds in total?
OR
Would you prefer having less (-216) lm301b leds but much more (+168) Cree 660nm leds and also 48 less leds in total?


Those of you that are familiar with HLG QB v2 boards, imagine those boards and the layout they have.
Conf1 has 2 leds rows taken out and instead have Cree 660nm in those places (picture 1).

Conf2 has the exact same layout as HLG QB boards but also added 8 Cree 660nm leds in between rows (picture 2).

So they arent quantum boards, how do u know they are lm301b diodes?
Meiku off Alibaba?
