It does matter.

Most kits do not have the right light to grow plants.

Can you tell us more about the light you have?
T-8? T-12?
All other info?

Have a look though the lighting forum for a lot more info, but here are the bare-bones basics:

For T-8 and T-12, wpg is not too far off. A 55 is pretty tall, I would aim for at least 2 wpg just for a low light tank. The light needs to be the right color for the plants. They use certain wavelengths more than others. A bulb that is rich in those wavelengths will grow the plants better, though it might make some colors in the tank (like orange fish) look funny.
