What should I do for lights in my new tank??

[reefwars]

Hey all so I'm thinking about my lights for my new set up, the tank is going to be 48"x48"x20"high it's going to have a center overflow for a full walk around tank with all sides viewable. Coral in this tank is gonna be fairly simple zoa's and some nem's maybe some lps. There will be no canopy so I need it to be clean. How do I go about lighting for all four sides??

I was thinking 6 mh pendants 2 for each side east and west and one for each side north and south but where do I put supplemnt lighting in there if I hang the pendants???

Am interested in any thoughts as I've never set up a tank like this and am a little stumped without spending thousands on lighting??? Thanks guys
