5x5 led strip build V2

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?

I'd use two Meanwell HLG-480H-42AB. Connecting pairs of strips in series for 39.2V is less wiring. Should be about 900 watts. At 11.4A per driver, 10 strips is 1.14A per strip and 12 strips is .95A. You don't need any heatsink at 1.05A and they'll run even cooler on some aluminum angle.


These terminal blocks are slick.

Is there any data to confirm temperatures of strips? I don't find them in PDF of Bridgelux. Because if I can go without heatsinks, I actually save around 40% of build cost. That would be nice. @1212ham

Love this and subbbed literatly doing very similar 4ft bxeb gen3 z boards. In a 6.6x6.5 and a 5x5 scrog.
Had to imporpt em from states lol.
Ive seen 2 arguments 1 saying better efficiency when ran hot 40w guy went from soft to hot..didnt find much on that
... everyone says run softerlike 25 to 30w.
So as i had to order in 20s i got the 480h 42ab drivers x2 at a steal and will run 28 to get 800ma 14 3500k on each driver giving 35w a strip meet em in the middle eh haha

I bugged these guys for weeks and cutter growmau both said dont go 3k and get 3500 straight . I wanted 3k bad .was gona mix 3500 and 3000 But they convinced me even tho its my flower light . Wont notice difference the blue helps thc more and stretching and has better green spec middle. and id see better straight 3500. Kinda bent my head outa whats id learnt best lol so i asked teknik and he said same pluss the boys here god damn i just accepted i was wrong lol

Will stay tuned as mine arrive il make a thred
