Though I haven't kept rams, I have just upgraded the light on my 35 gal tank one more time. I am now running 4 20W flourescents and 2 20W compact flourescents. The plants love it, and the apistos don't seem none the worse. I think if your tank is heavily planted enough, it won't bother the fish too bad because there will be lots of shade from the plants.
