The Amazon Sword would need more light. My experience with them is that they do poorly with low light. Plus they are deep rooters and will need some kind of fertilization. Also be prepared that these can grow huge. Mine are sticking out of the water and no other plant has survived in the aquarium because they have taken up all of the surface and no light can penetrate to the other plants.
But as far as the Java Fern are concerned they can do alright with the light that you have. I have a few Java Fern that I put in my 20 gallon aquarium with strong light and they have filled the whole tank and have taken over. Even after cutting down on the light they are reproducing like rabbits
. I cant figure out whether it is the water in my area (it is very hard water) or the lighting or the fact that there is minimal water changes in that aquarium or that there are few fish (3 loaches, 1 Gourami and 1 red tail shark)or that the fish will not eat or nibble on the Java Fern (even the red tail shark will not).
