Finnex makes a LED bar in their FugeRay line that will fit on a Fluval Chi. Amazon. You will want the 10" version.
I just started up a Chi tank (see signature) and it doesn't have carpeting plants. I would say the light is sufficient for a lot of things but nothing high light like dwarf baby tears. I have a Fluval Spec tank where the light is even dimmer and it will grow Staurogyne Repens. Over time they will spread and looks carpet like. You can pick that stuff up at PetSmart.
Final note. On the Chi you can't put the lights on a timer as the pump and lights all run off the same power. For that reason i dropped the whole filter thing (much to my wife's anger). In its place I used the FugeRay mentioned above and an Azoo Palm Mignon filter. I have just one Mignon 60 on the tank at the moment but getting ready to start up another. Note they do make bigger / stronger versions of the Mignon just not a Dr Foster and Smith.
