Reef lighting

[rusty]

Hello I have spent a couple hours reading and surfing the net this morning about this question, What are the best lights for my tank? the tank is only 10 inches tall, now the problem I have is I know a could two 250 watt halides over it and my sps will grow great, but I am looking for some thing that will produce the same results for cheaper. The thing with the halides is that I don't like how much power they suck back, does anyone know any articles or test done to see if the same wattage of VHO sucks back as much power? Or would I be better off going with T5's and if so how many would I need to be equivilant to 2 250watt halides? The tank is 45L x 20D x10H just looking for your guys opinion
