A Finnex Planted Plus 30 inch light should give you roughly twice what that light gives you, which would very likely be low medium to medium light. If it is a Planted Plus 24/7 light it could be dimmed if you need to do so. (And, later, when you decide you want to use medium light plants it would work for that.) At $85 I agree that it isn't the most economical light.
Incidentally, without actually measuring the light intensity any guess about how much light you have is just a guess. Now it is possible to borrow a PAR meter and find out how much light you really do have. Hint: there is a forum here where you can get stuff like this from other hobbyists.
