tbh I run a very Chinese brand Called Philzion...
they have a 605 true watt 6 COB/diode hybrid with two switches to run at half power...
cost me 370 each light....
claims 2522.8 umol/m²s each light at 18in lol....
6pcs COB, 110pcs 630-660nm, 12pcs 470nm, 12pcs 6500k, 4pcs UV, 6pcs IR...
have been amazing....
run just one at half power with just the COB in my 4x4 for veg and run full power for flower in the 4x4
use two in my 4x5x5.5 room and two in my 4x8 room
