I have spawned and raised rams in a Dutch tank enjoying 5x30w tubes. Water depth may be a variable (the tank mentioned has 18 inches), and water clarity also (a little healthy tanin will filter out a lot of excess brightness at substrate level). The short story is your rams will be fine, and your tank will look great.
