[*]Hello , i am new here but follow ledgardener his youtube channel all ready a while .
I bought 2 led bars of chill led the 40 inch , now they tell me that the max is 3500mA by 46v .
When i ask for the best mean well driver for the bars in series they tell me 1750mA because in series you have to divide by 2 (because of 2 bars ) ?
In series the voltage goes up but the mA stays the same yes ? I was looking on the channel
about the QB288 boards of HLG and there is explained like this ?
So i was thinking on the HLG-320-3500C / b , 320 because of the 160W for each bar and the 3500 because of the 3500mA max , but turn the build-in potentiometer a bit down so i don't exceed the maximum . The only problem is the voltage , 2x 46v = 92v and the driver have only 91v (95vf) .
I there a better solution ? and do i am so wrong in my thinking ?
THX for the help .

In series nothing will be cut in half. The current stay the same and the voltage will be added together(doubled in this case).meersie wrote: ↑Wed Apr 20, 2022 5:37 pm[*]Hello , i am new here but follow ledgardener his youtube channel all ready a while .

In parallel, the current will be cut in half(or how ever many parallel strings) but the voltage the same.
What are you trying to light up/do with these bars is what you need to figure out before specing the build.
