I think I settled on a middle of the line LED to increase my coverage. I'm currently running 2x Marshydro ts1000 at 150w ea. This worked ok for a 2.5x5 tent. i expanded to a 4.5 x 4.5 space and hope this light will do well. It came down to 320w with 3- qb288 or the 320w and 3 bars with the same LEDs. I'm leaning towards the bars. What do you think?
