Lighting for plants, help!!

I acquired some plants for my 29 gallon tank and I'm having a difficult time finding out which bulb I need. I have a fluorescent strip light on the tank and I'm sure the bulb I have in it now is NOT suitable for these plants. I've got moneywart and anacharis. I would like to get more plants eventually, but not until I get the lighting taken care of. I think I'll need at least 2 watts per gallon....but I can't find any bulbs 6500-6700k with that many watts. Any suggestions without having to change the hood and lighting fixture? thanks
