We need to know the information that has been asked before we can fully answer your question.
What is your tank size (gallons, and dimensions are needed)?
Do you have an existing light fixture on the tank, and if yes, what type (fluorescent, incandescent) and if fluorescent, how many tubes and what is their length (this differs usually from the tank length, so we need both)?
There are many, many plants suitable for a gourami aquarium that can be grown with low and moderate light; and I wouldn't have bright light over a gourami tank, they ar sedate fish that live in heavily planted swamps and streams with shade from overhanging vegetation and floating plants. Once we know the above information, we'll easily answer your question.
