Ohh btw Welcome to Tropical Fish keeping!

For a cheap alternative (and one I have successfully been using) is to use clip on desk lamps, with 6500k spiral CFLs. I use one on my ten gallon (clipped to the side and aimed to light the whole tank), but you could even use two clipped onto either the back, or both sides.
I have planted Anubias, Lace Java Fern, Dwarf Hairgrass and Dwarf Baby-tears. I noticed that the Anubias has been thriving, The Lace is fairing well but the ground cover plants are not doing so well.
This tank only has two inhabitants, rather small to the tank(Betta & African Dwarf-frog) I am considering the possibility of there not being enough food for the plants so I am looking into that now as well.
