You can check Hoppy's charts to confirm, but the Coralife T5NO is not a particularly bright light and the reflectors are pretty poor. I believe you'll be in low light...I actually plan on buying it for my 20L where I intend on growing low light plants and moss. Like somewhatshocked said, if it does end up being a tad too bright, there are very easy ways to reduce the amount of light coming through.
