I recommend T5HO lights. For plants you want plant bulbs in the 6500K range for optimum photosynthesis. The wattage/lumens needed will depend on what plants you want to grow. I highly recommend researching the plants you want and buy accordingly. Nothing is more frustrating than shelling out your $$$ to find out later that you need something more. Lighting is one of the most expensive parts of this hobby, so do your research first. here is a site that has some info like you will need. It tells you about the plants plus what their needs are.
Aquarium plants, and aquascape plant packages
Look around your local lfs's and see what is available regularly and ask if they can order something specific for you, just in case you find something that you would really like.
Like most everything else in this hobby, my first advice is research, research, research. Then you can make an informed decision. Believe me, your wallet will be much happier.
