help with lighting

[EL BIG PETE]

Hi I just started a 150gal build .My plan is to turn it to a sps tank (first time reefer)need help with lighting . My tank is 5ft long X 2ft wide x2 ft deep. I was planing on using some basic reflectors(3) and galexy ballast . Can someone tell me if I really need 2 go with 400 watt ballast or are 250's good enough? :question:
