Hey guys/gals, i have a 4x4 tent that up till now i haven't really maximized(only upgraded to it this year to begin with) and am getting ready to fill it out this month. I currently have a 135 watt QB and was wondering my best options to fill it out. My first thought is a 260 which should cover 3x3 plus my 135 2x2 and thats 3x4 or just shy of the whole tent which i wouldn't mind since i don't want plants touching walls anyways. If that is my route what 260 is best? Reg/XL/XW? 320 is sold out which im guessing is 4x4? Would just buying 2 more 135 be better than 1x 135 and 1x 260? Trying to concider cost as well as easy to hang for light footprint max. Thanks.

Where I was going with this was that the kits elude to being 320 watt but with the HLG 320H-1750s that I thought they used, you can't hit 320 watts. I suppose I should have bought CV drivers instead to squeeze out a bit more potential. I am building two fixtures with three QB288s each running on the above mentioned driver. I pull 1.767A at 50v, giving me 88.35 watts per board with a total of 530 watts. Perhaps a bit skinny on the wattage for the planned 5x5.

b type driver and a cheap potentiometer? hlg-320h-1750 will output 2 amp.

So with the potentiometer installed, they drop the constant current mode? I am awaiting some on order from rapidLED to install until I add more diode boards and/or strips and go with some sort of controller.
