What light to use for planted freshwater tank?

[Absolute2purity]

What kind of a light would be good for plants to grow/sustain themselves in a 75 gallon tank? I have a full grown goldfish w 2 java ferns and i want to get hornwort and different plants.

If you stick with low light demand plants like the java fern you have and the hornwort you are considering then pretty much any aquarium light will suffice.
