Rather than thinking about lighting in terms of wattage, it is best to think about it in terms of photosynthetically active radiation (PAR).

Here is a good article written by Hoppy regarding the topic:

You can determine how much light you will have at substrate level using the chart.

It depends on the height of the tank, and the quality of the brand of fixture.

You should find your answers in the article above though^^

thanks for replying guys my tank is 12 deep and my light fixture would be 4 inch above tank.

48 watts over only 16 inches seems like it would make it high light

You will need to specify if you are using T5NO or T5HO as well.

As mentioned, the lighting fixture that you are using will also affect the amount of lighting you have (i.e. whether they have reflectors, etc)

Here is a more up-to-date guide written by Hoppy for your perusal.
