That all depends on how "bright" you want the tank..
Your tank doesn't need light if you just have fish...But you do for your own visual needs.. So its all about what YOU want the tank to look like..
I would suggest just starting with one and simply adding more if thats not sufficient.. No need to make guesses,etc.. at how many you need.. Buy one.. If its not enough.. buy another.. plain and simple..
I don't even think I'd use the current one if I was in your shoes.. ~$300 is a lot of money IMO to spend on lighting for a fish only tank..
You can pick up "similar" ones for under $100..
