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.

mitchfish9 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^^

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