U got a point bro. Why waste the 5k inv3sted in that space when i still need 2 more lights. Kinda wasting time . I did get some badass fruit this time but its gonna be better after those 2 more lights. In all honesty even at 4 600s im only using 400 more watts. I hear at 600 watt its still putting out around 90k lumenz. Whereas the 1k does about 30k more i believe only. Im just wondering if the 600s are gonna be enuff 10 ft high room 12 ft long 10 ft wide.
