After 3 years running 20x LT-QB22A on 2x 240W drivers in 4x4 tent (2.8 umol/s, 184 lm/W I think), it's time to go into 5x5 tent.
I am looking for little help with design, I am little out of the league after those years.
750-1000W is what I want.
20-30 strips is what I want.
I found Bridgelux gen3, at 1.4 A they already run better than my old Q's, at 185 lm/W. Because I am "efficiency guy", I want to run them at 1.05 A to get into 190 lm/W or higher. That way I can prolong their lifetime and don't need big heavy heatsinks. Can you help me with number of strips and proper drivers please?
