Hello Olsqueak.

I'm not sure to be honest but if a dimmer switch is anything like a fan step controller, it may well be that the
Current that runs to the dimmer is always constant, even when you turn it up & down. I'm may be wrong though.

Peace

HAVE PEOPLE BEEN TAUGHT DIFFERENT THINGS OR ARE THEY TAUGHT ABOUT THE SAME THINGS IN A DIFFERENT WAY? THERFORE THE PEOPLE HAVE A DIFFERENT VIEW & UNDERSTADNING OF WHAT REALITY IS ALL ABOUT BECAUSE IT WAS TAUGHT TO THEM, IN A DIFFERENT WAY, FROM WHAT REALITY REALLY IS.

It´s a potentiometer, no switch.
The Hlg-185h-c1400A version have one inside, you can dim from 50-100%.
With he Hlg-185h-c1400B it´s possible to use a external poti, from near 0-100%.

Yes, that´s right.
My cob bars are 15-20cm above the tops.
But be carefull because your cob has more power then mine.

This is a bit of a long video, but interesting. He also shows exactly how to turn up and down the wattage and what parts to use. It may be useful for you

For having better lumens output i must use cxb3590 72v 3500k at 50 watts (8000 lux*4 total 32000 lux with Hlg-185h-c1400a 200watts)
If i order 4 cxb3070for my second driver i can have total aprox 64000 lumens.
Cxb3070 36v 3500k price is 20 dollars if i see well.
Hlg-185h-c1400a is for maximum 2 cxb3590 72v Series.
A member from other place say me than i can connect 4 cxb3590 72v parallel in One driver Hlg-185h-c1400a ? Do you think it's possible ?
Thanks for all your help friendly Olsqueak

It's possible but in case of cob failure you'll need some fuses for protection.

Hello,I can have Vero29 at approximately same price than cxb3070.
They only have 3000K no 3500k.
I know than 3000k is good for flowering.
If I mix 3000k and 3500k is ok for make Grow and Flower ?
Or it's better I use only 3500k ?
Thanks

I would not expect much difference. People at rollitup used to advocate 5000K for vegging but now I think most people use from 3000K to 4000K for everything.
