Those lights are negligibly better. As mebbid stated you have a very deep tank so par will be a problem.
And don't worry about the carbon taking the ferts out. Carbon usually exhausts quickly and just becomes another home for BB. I run media in my HOBS for months before making changes.
I would return the bulbs, save the money, do some research on planted tanks. Start with low light plants to get a handle on plant care.
Once you know what direction you want to go in you can start saving toward a fixture that will fit your needs(and your tank).
