Best placement of 4 lights?

I have four 600 watters but dont know which direction to hang them. I have done two renders which should pretty much show you what I'm asking. My aim here is to maximize light spillage and also reflection from the walls. Nothing is to scale here (yet) but each light will be covering about 3.5 feet (1meter) squared.

Which way is correct, A or B?

the 600 watters were a good choice u can put them closer to the plant without burning them and there is a more even distribution of light, my researching is saying figure b is best for reducing light leakage

i would say the first way...it shouldn't really matter tho,i would recommend buying mylar to cover those back walls instead of the stuff you have back there,the mylar would reflect the light so you wouldn't have to worry how your lights are turned, htgsupply.com has excellent prices on mylar,dont know if i helped or confused you lol

Lokkin' good with your light setup. Either way will work.

Thank you everyone! I think I may just go with A because it could be easier to cool.

BTW, There is nothing on the wall yet, those are just 3D renders. But yes, I will be using Mylar (just couldn't get it to look like mylar for my render).
