1000w vs 600w vs 400w

i am looking to set up a 2000w room with 30 plants
which one should i go with:
2 1000w
3-4 600w
5 400w

with more lights i can cover a bigger area but the lumens differ greatly between these lights...
which one would you say is best?
what would be the difference in yield at the end?

i would choose 4x600w,with yoyo's keeping ur lights 2/3ft above your plants for max lumens..

that is what i would do as well . you get the best lumen bang for your electric buck with the 600 watters

i would go with 2 1000w and a light mover..more lumens is all that matters, and 2 1000w can give u that if i am not wrong...

par watts is what really matters lumans are for humans... fast veg with those 1000s big ass total area with four 6s
