I had Spider Farmer sf1000 . Good Lights! They make some awesome stuff. I just bought the ac infinity Evo 8 for my 4x4 like yours. I can't tell you anything other than this is my first grow with it. I liked the programing side of it and also wanted to give the samsung evo lm301h a try .  I am liking the cloud controller. The Kind is a spectacular light as well. Now a days just flip a coin lol. Good luck BigSarge
