I've used them for a few years in my 6 gal
. hex, and the plants do very well.
I'm only growing Crypts, Anubis Nanas, and Sunset Hygo, so I'm not dealing with anything very challenging, but then neither are you. You should have no trouble with hornwort and java moss.
Some of the newer CF
's are smaller than they used to be, and are easier to fit into a hood. I've found the "daylight" versions work nicely, and to my eye look better than the "warm white."
