And why is is that you feel you need so much? If you wish to light it using
watts as a guide, 2watts per gallon would be sufficient. Most of the
common aquarium plants will respond well to this.

The wattage formula of 2W/gal or 3W/gal is adequate to determine the proper
lighting when using tubes, however I still believe it is necessary to
investigate the Color Rendition Index of said tubes to get at least some idea
of where you're going. In my calls to lighting dealers I have never had much
trouble obtaining this information.
Obviously, Karen has either done that and been there, or got lucky! I doubt
that it is the latter. 8-)
