You could use the FishNeedIt 2 bulb T5HO light, http://www.fishneedit.com/t5ho-3ft--2lamp-aquarium-light.html and get medium light, perhaps low medium light. With that light and CO2 you could grow just about all of the plants you might want to grow. Higher light would likely give you better color of the reddish plants, but not for sure, but the price would be a lot more problems avoiding major algae attacks.
