I havent looked into those that much. I looked over them and went straight to qb288 setups. but i think the issue isnt the wattage but the coverage area during flower? i guess it depends on the number of plants in the tent. i think its like a 3x3 flower foot print. I ended up ordering 6 sets of 240w qb288 to fill out a 4x8 tent. Mostly went with 6 sets so i could improve coverage over 2 per 4x4. ran me just shy of $800 from china.
